TYPE: U.S.A. Texas.[ San Felipe de Austin],s.d.[ Apr.1834], T. Drummond II 40 [ LECTOTYPE, designated by Dorr (1990: 48): NY [ NY00221809 ] !; POSSIBLE ISOLECTOTYPES: BM!, E!, G [ G00353067 ]! [“40”], G [ 00353144 ]! [“40”],OXF!) ].

Although this species is presented simply as “ M [ alva] lineariloba ” in Young’s (1873) flora, it is a new combination based on M. involucrata var. lineariloba (see e.g., IPNI 2021; Tropicos 2021). The description published by Young is almost a verbatim copy of the description of the variety published by Torrey and Gray (1838) except that she did not include Torrey and Gray’s parenthetic description of the length of the flowers, and she omitted their note that their description of the carpels was based on immature material. Both floras only cite “ Drummond .” Thus, it appears that Young (1873) provides “a clear (if cryptic) indication, by an author citation or in some other way, that a previously and effectively published description or diagnosis applies” ( Turland et al., 2018; Art. 38.14; emphasis added).

The lectotype is a specimen in the Torrey Herbarium (NY). Apart from “Tex. II” penciled by Torrey on the label, there are no locality data, and there is no collecting date. McKelvey (1955) noted that Drummond visited San Felipe de Austin in August and October 1833 and again in April 1834. Consequently, Dorr (1990) inferred that Drummond collected the type material of this spring-flowering species on the latter trip.

Several herbaria have Drummond specimens of Malva involucrata var. lineariloba from Texas that are no. 40 in Drummond’s “Coll. III.” These include: K [K000659302]! [“No. 40 Third Collection, Texas Drummond , 1835”], K [K000659303]! [“ Texas III n. 40, San Felipe”], K [K000659304]! [“ Texas III, nr. 40” & “San Felipe”], NY [NY00221810]! [“Coll. III. No 40”], and P [P02286260]! [“III–40”]. At least two of these specimens indicate that they were collected in “San Felipe [de Austin].”
