Trelease (1924, p. 85) wrote “ (Pringle, 74, 355, the type) ” which would appear to make Pringle 355 the type collection number. He also cited Pringle 970, which based on what he wrote on page 85, would make Pringle 970 a paratype. In the caption to pl. 129 a and pl. 129 b on p. 220 he wrote “ The type collections (Mexico, Pringle: a, no 74; b, no 355). Photographed by permission at Dahlem. ” However, in the caption to pl. 130 a on the same page he also wrote “ The type (Mexico, Pringle 970). Photographed at St. Louis. ” If taken all together, our interpretation is that Trelease cited two syntypes for Q. chihuahuensis with one being Pringle 355 at B, now destroyed, and the other being Pringle 970 at MO. We are lectotypifying the name based on the existing syntype at MO. The placement of this species needs additional study, but we consider the type to fall within the variation found within Q. alveolata as broadly interpreted.

Trelease (1924, p. 86) cited Schumann 1310 (p. p.) as the type of Q. chihuahuensis f. tenuis, but on p. 220 in the caption for pl. 131 a, he cited Schumann 1300 (p. p.) as the type at B. The second citation is most likely a typographic error and should have been 1310 (p. p.). The specimens at US of 1310 which we are designating as the lectotype match the description in the original protologue. Quercus chihuahuensis f. tenuis Trel., Mem. Natl. Acad.

794B8792FFF4FFD63E88FF67FD5FFA31.taxon	distribution	Distribution: Belize, El Salvador, Guatemala, Honduras, Mexico (Chiapas, Oaxaca), Nicaragua. The occurrence of Q. segoviensis in Michoacán reported by Villaseñor (2016) is probably incorrect. Quercus sideroxyla Bonpl., Pl. Aequinoct. 2: 39, pl. 85 (1809). Type: — MEXICO, Guanajuato: A. Bonpland 4219 (p. p.) (Holotype: P 00129702!; isotypes: P!, UCSB (fragment)!). Three sheets at P of Bonpland 4219 from Villapando are Q. sideroxyla, the holotype and two isotypes. Collections with the same number but from Santa Rosa are Q. tridens and are not types. Quercus incarnata Trel., Mem. Natl. Acad. Sci. 20: 126, pl. 230 a (1924). Type: — MEXICO, Chihuahua: R. Endlich 782 b (p. p.) (Holotype at B destroyed. Lectotype (designated here): image in Trelease (1924, pl. 230 a)!). No isotypes exist of this species or any of the forms described by Trelease, and the other Endlich paratypes of the species at B were also destroyed. The two Arsène paratypes of Q. incarnata are other species (Arsène 5807 = Q. scytophylla and Arsène 6036 = Q. castanea) so they cannot be used as possible lectotypes. Quercus incarnata f. ampla Trel., Mem. Natl. Acad. Sci. 20: 127, pl. 229 b (1924). Type: — MEXICO, Chihuahua: R. Endlich 782 b (p. p.) (Holotype at B destroyed. Lectotype (designated here): image in Trelease (1924, pl. 229 b)!). One must assume that Trelease’s (1924) pl. 229 b is of a branch from a different plant than the branch shown as pl. 230 a which is of the holotype of the species. Quercus incarnata f. grosse-serrata Trel., Mem. Natl. Acad. Sci. 20: 127, pl. 231 a (1924). Type: — MEXICO, Chihuahua: R. Endlich 782 d (Holotype at B destroyed. Lectotype (designated here): image in Trelease (1924, pl. 231 a)!). No extant original material exists, so we are lectotypifying the name based on the image of the holotype. Quercus incarnata f. longa Trel., Mem. Natl. Acad. Sci. 20: 127, pl. 230 b (1924). Type: — MEXICO, Chihuahua: R. Endlich 782 a (Holotype at B destroyed. Lectotype (designated here): image in Trelease (1924, pl. 230 b)!). Trelease (1924, p. 127) cites Endlich 728 a as the type, but on p. 223 in the caption to pl. 230 b he cites Endlich 782 a as the type. It is likely that the first citation is a typographic error, but in any event the collection at B was destroyed. Because no extant original material exists, we are lectotypifying the name based on the image of the holotype. Quercus omissa A. DC., Prodr. 16 (2.1): 28 (1864). Type: — MEXICO, Sinaloa: B. Seemann 1969 (Lectotype: K 000512899! designated by Trelease (1924, p. 223, pl. 231 b); isolectotypes: BM!, C (as s. n.), G!, GH!, UCSB (fragment from K lectotype)!, UCSB (fragment as s. n. from C)!).

Newberry (1859, p. 28 – 29) cited Q. tinctoria var. californica as a synonym and indicated that he considered it to be neither Q. tinctoria nor Q. coccinea Münchh. although similar to both. He would also have been aware that Torrey (1857, p 138) thought that Q. tinctoria var. californica could be a new species when he wrote “ it is probably a distinct species. ” For these reasons we consider Q. kelloggii to be a nom. nov. for Q. tinctoria var. californica based on the same type (Bartholomew & Almeda 2022). Quercus californica (Torrey) J. G. Cooper, Smithson. Rep. 1858: 261. (1859). Nom. illeg. because Cooper cites Q. kelloggii Newb. (1857) as a synonym which is an older name.

Torrey noted that “ The greater part of the botanical collections made by D. J. M. Bigelow, in the Pacific Railroad Survey, under the charge of Captain Whipple, were submitted to me for examination in accordance with the instructions of the War Department. ” Torrey also had available to him other collections which were in the Torrey Herbarium now at NY, including examples of the same oak made during the Wilkes Expedition of 1838 – 42, Frémont’s Expedition to California in 1845 – 47, and the Emory expeditions with a collection by C. C. Parry in 1850. It is clear that he relied on the collection localities of all these specimens when he wrote “ It occurs throughout the valley of the Sacramento, and as far south as San Diego. ” All of these NY specimens are syntypes including the collection J.

Collections cited by A. de Candolle (1864) correspond to Liebmann 3505, some of which were collected in Oct 1841 and some in Nov 1841, but all at the same locality of S. Bartholome. A. de Candolle cites specimens as “ Q. lancifolia Liebm.! in h. Copenh. et DC., non Cham. et Schl. ” Of the six specimens originally at C, one is now at CAS. All six specimens were determined in A. de Candolle’s hand as Q. leiophylla. We have chosen one of the C specimens collected in Oct 1841 as the lectotype which is also the holotype of Q. lancifolia var. monocarpa Wenz.	en	Bartholomew, Bruce, Almeda, Frank (2023): Nomenclator botanicus of Fagaceae in Latin America.

No specimen of Ross 579 was found at M, but there is a specimen of Ross 519 which is the specimen photographed in pl. 62 b. Trelease misread the “ 1 ” as a “ 7 ” which is an easy mistake to make. We have determined the M specimen of Ross 519 to be Q. obtusata. Note that Trelease (1924, p. 62) in the specimens examined statement for Q. obtusata does cite “? Ross, 519 ” indicating that he was uncertain, at least at one time, if Ross 519 was actually Q. obtusata, but he decided that it belonged to his new species Q. panduriformis. Because two different collections were cited by Trelease as the type of Q. panduriformis, one of which is now lost, as well as a typographic error in citing the extant specimen, we are designating Ross 519 as the lectotype of Q. panduriformis.	en	Bartholomew, Bruce, Almeda, Frank (2023): Nomenclator botanicus of Fagaceae in Latin America.

Trelease (1924, p. 49) indicated that “ Liebmann, 156, 3483 ” is the type, so the specimen of Cupulif. Lbm. 156 at C would apparently be the holotype. However, in the caption of pl. 35 a on p. 217 Trelease wrote “ The type Mexico, Liebmann, 156 ” and indicates that this image was taken at B. It would seem more likely that the specimen at B would have had just the number 3483 on it, which is an assigned number for a particular collection, rather than just Liebmann 156 which is an assigned number for individual sheets. Because the specimen at B was destroyed, and the label is not shown in Trelease’s pl. 35 a, it is impossible to know for certain what was on the B label. For this reason, we are lectotypifying the C specimen Cupulif. Lbm. 156.

Quercus toxicodendrifolia Trel., Mem. Natl. Acad. Sci. 20: 48, pl. 33 a (1924). Type: — MEXICO, Hidalgo: J. Berlandier 533 (p. p.) (Holotype at W destroyed. Lectotype (designated here): G 00358149!; isolectotypes: BM?!, P?!, UCSB? (fragment)!). The holotype of Q. toxicodendrifolia was collected on 21 May 1827 and is cited by Trelease (1924, p. 48). Collections of Berlandier 533 made on 19 May 1827 cannot be considered type specimens although G has a specimen from each of these dates. The G specimen of Berlandier 533 dated 21 May 1827 is the one here designated the lectotype. In the case of Berlandier 533 at BM which is undated, it can only be considered to be a possible isotype and now becomes a possible isolectotype. In the case of the P specimen there is a date of 21 May 1827 on the label but no number. Because Berlandier made collections of the same oak species using number 429 on this date, the P specimen can also only be considered a possible isolectotype. In the case of the fragments at UCSB, one of the Berlandier 533 fragments is dated 19 May 1827, so it is not a type collection. Another Berlandier 533 fragment is undated so it could be a possible lectotype fragment, but the leaf size is much larger than those of the lectotype and is probably from the G collection of 19 May, so it is not a lectotype fragment.

DC., Prodr. 16 (2.1): 67 (1864). Type: — U. S. A., California: F. A. Wislizenus s. n. (Nov 1851) (Holotype: MO- 204635 (image)!). The holotype of Q. wislizeni was collected in November 1851 at the American Fork of the Sacramento River near Auburn. It was collected by Friedrich Adolph Wislizenus (1810 – 1889) and sent to A. de Candolle by G. Engelmann. W. Trelease, C. H. Muller, and K. C. Nixon all considered the MO specimen to be the holotype, and the specimen has label information in A. de Candolle’s hand. There is an inconsistency with the A. de Candolle publication which gives the collection locality as being from Chihuahua in the mountains of western Mexico in the vicinity of “ Cosiquiriachi ” (which is likely Cusihuiriachi) at an elevation of 7000 ft. Trelease (1924, p. 205) considered that A. de Candolle had erroneously ascribed that type to the Mexican state of Chihuahua. Certainly, the MO specimen is the species that occurs in California and only ranges into the Mexican state of Baja California. Distribution: Mexico (Baja California), U. S. A. (California). Quercus xalapensis Bonpl., Pl. Aequinoct. 2: 24, pl. 75 (1809). Type: — MEXICO, Veracruz: A. Bonpland 4467 (Holotype: P 00129754! (as s. n.); isotypes: B-W!, P!, P!, UCSB (fragment)!). The holotype at P (s. n.) has a description on it in Bonpland’s hand. The other two specimens at P (s. n) as well as those with the number 4467 at P and elsewhere are all considered to be isotypes.
