It has not been possible for me to see the type of 
Hormidium Hiorami. However, a study of the original 
description convinces me that it is very probably refer- 
able to the extremely variable Mpidendrum pygmaeum. 
Until it is possible to examine the type or a photograph 
of the type of H. Hiorami, with some reservation it seems 
best to include it in this species. HLormidium Hiorami, 
was invalidly published since no Latin diagnosis was 
given by its authors. 
This species occurs in southern Florida, Mexico, 
throughout Central America to Panama, Cuba, Jamaica, 
Puerto Rico and northern South America.

An examination of the type of Spathiger Roigi (in 
Herb. New York Bot. Gard.) and a comparison of this 
material with a sheet in the Gray Herbarium of /’pi- 
dendrum ramosum var. lanceolatum (Wright 3333, cited 
by Grisebach Cat. P]. Cub. (1866) 263) shows that these 
two plants are identical. The type of Spathiger Roigi 
is also identical with a sheet in the Ames Herbarium 
(No. 7055) which was compared by Ames with authentic 
material of H. ramosum var. lanceolatum at the British 
Museum. 
Variety /anceolatum differs from the typical form of 
the species (and its other varieties) mainly in the type 
of inflorescence and the somewhat larger flowers. The 
flowers, instead of being borne in a raceme as in the
