which little exceed the width of the mid-lobe. Further- 
more, the petals of the variety taper more gradually from 
their tip to their base and the mid-lobe of the lip is some- 
what more elongate than in the typical form. 
Mexico, State of Sonora, greenhouse grown specimen from plants 
collected in 1910 above Alamos. J. N. Rose 10.1102 = 13062 (Tyrr in

The collection, Rose 1533, has lateral lobes of the 
lip which are intermediate between the species and the 
variety. 
Epidendrum arbuscula Lind/. var. radioferens 
Ames, Hubbard & Schweinfurth var. nov. 
A typo labello obscure lobato, laminae venis carinato- 
incrassatis differt. 
Lip indistinctly 4-lobed, nearly orbicular in general 
outline, with the margin crenate-plicate and the radiating 
veins of the lamina strongly carinate-thickened; lateral 
lobes semiorbicular; mid-lobe orbicular-renitorm, divided 
into two rounded lobules, separated from the lateral lobes 
by an indistinct sinus. 
This variety differs from the typical form in having 
the lip less distinctly lobed and the radiating veins of the 
lamina carinate-thickened. 
The Heyde and Lux specimen cited approaches the 
typical form in having a sharp sinus and less crenate-pli- 
‘ate margins.
