This var. differs from var. flavida Reichb. f. (Ref. Bot. ii. t. 79) 
in the flowers being much smaller. 
In examining material in connection with our work we noticed 
that Lindley had included under Stelzs set Anon Sw. no. 
1025 of Schomburgk’s collection in British Guiana (Hook. Lond. 
Journ. Bot. ii. 670, 1843). The specimen, however, under that 
number in Herb. Mus. Brit. is quite unlike Swartz’s specimen. 
It differs also from the three species known from Roraima, viz. 
S. tristyla Lindl., S. grandiflora, Lindl., and S. > soem Rolfe, 
and from S. Heyli idyana Focke ceca and S. zonata Reichb. 
f. (Guiana). It may be described as follows :— 
homburgkii. Ca ules dete ceespitosi, erecti, 1- 
articulati. Folia satis coriacea, lineari-ligulata, apice obtusa, basi 
in petiolum longe attenuata, caulibus longiora. Racemi solitarii,
