to be unquestionably an Hclogyne probably identical with H. Wehcr- 

 baueri Robinson, Proc. Am. Acad. xlii. 32 (1906). The plant there- 

 fore should bear the name Helogyne straminea (DC), comb. nov. 

 E. Vauthierianum DC. Prod. v. 159 (1836). By Baker in Mart. 

 Fl. Bras. vi. pt. 2, 305 (1876), this species is said to extend from 

 Peru to Panama and Nicaragua. Baker, 1. c, cites certain specimens 

 including Hayes's no. 589 from Panama and one of Tate's from Nica- 

 ragua. These are subsequently cited by Hemsley, Biol. Cent.-Am. 

 Bot. ii. 102 (1881), under E. vitalba[e] DC. As E. vitalbae is a species 

 well known and widely distributed from Peru to Nicaragua, while E. 

 Vauthierianum is decidedly a plant of Atlantic Brazil, by no one else 

 recorded in the Andean countries, there can be no doubt that Baker's 

 note was intended not for E. V autJiierianum but for E. vitalbae, as 

 confirmed by Hemsley's subsequent placing of the same Central 

 American exsiccatae.
