The receipt of an excellent photograph of the type of 
Stelis floribunda and some of the dried flowers of this 
specimen from the Muséum d’Histoire Naturelle at 
Paris show beyond question that it includes the concept 
described as S. insignis Ames. 
The latter species diverges from S. floribunda in its 
somewhat greater vegetative size—the stems are up to 
about 19 cm. tall (contrasted with a maximum of about 
10 cm. in S. floribunda); the leaf-blade is up to about 
13 cm. long and 8.5 em. wide (contrasted with a length 
of about 8.2 cm. long and a width of about 2.9 em. wide 
in S. floribunda). Its sepals also vary from obtuse to 
subacute. 
It appears that the shape of the typical leaf of 8. florv- 
bunda is oblong-elliptic, but a Colombian collection 
( Lehmann 6921), which is correctly referred to that spe- 
cies by Kriinzlin, has leaves varying from narrowly ellip- 
tic-oblong to narrowly oblong. 
A series of Peruvian collections referable to S. flori- 
bunda differ from the typical form in having leaves which 
sometimes attain a width of 4cm., in having commonly 
but a single inflorescence instead of two to four in a clus- 
ter, and in having flowers which are described as greenish 
white instead of violet (as cited for S. floribunda).
