bristles resembling: the peripheral ones but shorter, whereas in 
the latter the bristles on the faces are very short. or almost sup- 
pressed. The former is represented in the Kew Herbarium from 
Jalisco only, and the latter from Morelos only. The reasons 
given by Mr. Watson* for uniting the two species do not seem 
adequate.

r. Watson cites numerous specimens from San Luis Potosi, 
Vera Cruz, Chiapas, and Guatemala in addition to the type, 
which is Linden 2065 from Tabasco. Mature fruit of the Tabasco 
plant is not known, and it is therefore difficult to determine 
whether the specimens from Guatemala are really conspecific. 
An allied species from Chontales, Nicaragua, is represented in the 
Kew Herbarium. This differs from the Guatemalan plant in 
the much smaller capsule, only 8-9 mm. wide including the 
bristles, and with a broadly elliptic body, rounded above, and a 
shorter stipe. These differences are not due to age, as the seeds 
are ripe in both cases. The Nicaraguan plant may be dis- 
tinguished from H. appendiculatus (both Tabasco and Guatemala 
specimens) by the indumentum of the lower surface of the leaf, 
which has numerous relatively large fulvous stellate hairs forming a 
second tier above the fine greyish tomentum. It may be known 
as H. chontalensis.
