Triplaris vestita Rusby (1927: 236–237)

Type (designated by Brandbyge 1986):— BOLIVIA. [La Paz Department, Cañamina, on the] Meguilla [River], 3000 feet, July 1921 (fr), H. H. Rusby 2175 (lectotype: US [ US 102488!], isolectotypes: GH [ GH 36853, digital image!], K [ K 585006, digital image!], NY [ NY 324258, digital image!]).

Notes:— The isolectotype NY 324258 reports a different elevation (“ 3250 ft ”) and a different locality (“Cañamina on the Meguilla River”) than the other duplicate specimens. The protologue by Rusby (1927: 237) mentions “Meguilla” but not Cañamina. Meguilla is not a known habitational location in Bolivia, being the name of a tributary of the La Paz River. Cañamina is a known camp site of the Mulford Exploration, on which this specimen was collected. Thus, “Cañamina on the Meguilla River” seems the proper specification of the type locality.

Triplaris weigeltiana (Rchb.) Kuntze (1898: 270) ≡ Blochmannia weigeltiana Rchb. (1828: 163) ≡ Triplaris surinamensis Cham. (1833: 138) . Type (of Blochmannia weigeltiana , further designated here):— SURINAME. 1827 (fr), Weigelt s.n. (lectotype: B [B 10-0250409,

digital image!]; isolectotypes: B [ B 10-0250408 , B 10-0250410 , digital image!], BR [ BR 5288083 , BR 5314157 , digital image!] ,

G [G 437659, digital image!], MO [MO 216276, digital image!], NY [NY 00324213(fragment), digital image!]).

Notes:— This name was validly described by Reichenbach (1828: 163) as a name on Weigelt’s Exsiccatae “Pl. Sur. exsicc. 1827” as Blochmannia weigeltiana (see Art. 30.8 of ICBN and Nicolson 1980).

Brandbyge (1986) correctly designated a B specimen as the lectotype. However, since there are three Weigelt specimens at B, Brandbyge’s (1986) proposal represents an initial but incomplete lectotypification (Art. 9.17 of ICBN). We here further narrow the lectotypification to consider B10-0250409 as the lectotype of B. weigeltiana . B10-0250408 and B10-0250410 are isolectotypes.

The G437660 and MO216275 specimens, among the other important specimens, do not display the same label and information as the rest of the type specimens. Brandbyge added a label that indicates they are probably isolectotypes. We mention them here, but do not include them in the list of isolectotypes as we cannot be certain of their origin.

Blochmannia weigeltiana was later moved to Triplaris by Kuntze (1898), who referenced Weigelt’s specimen and description. Confusingly, Brandbyge (1986) designated the same specimen as type of both T. (B.) weigeltiana and T. surinamensis (see discussion under T. surinamensis above).
