Colubrina texensis (Torr. & A. Gray) A. Gray, Boston J. Nat. Hist. 6:169. 1850 View in CoL .

Rhamnus texensis Torr. View in CoL & A.Gray,Fl. N.Amer.1(2):263.1838 (“ R.?Texensis View in CoL ”); M.J.Young, Familiar Lessons Bot.204.1873 ( “ Texensis View in CoL ”).

TYPE: U.S.A. Texas. Sine loc. ,s.d., T. Drummond II 67 ( LECTOTYPE, designated here: NY [ NY00415024 as image!] ; POSSIBLE ISOLECTOTYPE: G [ G00440908 as image!] [“67”] ).

Rhamnus drummondii View in CoL is one of four species of Rhamnus View in CoL L. recognized by Young (1873).She lists it simply as “ R. Drummondii View in CoL . ” No author is given nor is a collection cited. Interestingly, her description comes very close to being a verbatim copy of the second paragraph of the protologue of R. texensis View in CoL published by Torrey and Gray (1838) with simply the omission of the phrase that begins this paragraph, viz. “ Texas, Drummond ! (coll. 2. no. 67).”

Rhamnus texensis View in CoL was also accepted in Young’s (1873) flora.In this instance, her description is a verbatim copy of the first paragraph of the protologue of R. texensis View in CoL published by Torrey and Gray (1838) with merely the parenthetic and speculative phrase “(flowers solitary?)” omitted (and, of course, the second paragraph suppressed in its entirety).

Johnston (1971) effectively designated a lectotype for the name Rhamnus texensis View in CoL when he stated that the holotype was a specimen at GH. However, the specimen he selected was from the third (III), not the second (II) collection of Drummond and thus does not agree with the protologue and can be superseded. Moreover, the GH specimen was acquired well after the publication of the name and cannot be considered original material. Specimens of R. texensis View in CoL from the third collection can be found in the following herbaria: BM [BM000838445 as image!] [“III, 67”], GH [GH00139465 as image!] [“III 67”], K [K000729226 as image!] [“Third collection, No 67”], P [P01818876 as image!] [“III, 67”], and US [ US 00094445]! [“III 67”].
