﻿536 Underwood : The terxate Species of Botrvchium 



Bourgeau's Orizaba plant, no. 3194, in the same collection, are 

 fairly typical forms as figured in the original publication. A ster- 

 ile plant in the Columbia Herbarium, collected in Orizaba by 

 Muller, is also fairly typical of the species as originally described 

 and figured. Not all the Mexican forms of this group can be re- 

 ferred to the same species. Besides B. obliquum there are, at pres- 

 ent, indications of at least three distinct species from Mexico, and 

 while these are already represented by specimens in our own col- 

 lection, detailed information regarding their characters, habits, and 

 distribution is veiy much desired.

clearly defined species, its alliance being with B. daiicifolium. The 

 type is at Washington in the National Herbarium and duplicates 

 of it are at Kew together with two other specimens both im- 

 perfect ; in the Berlin Herbarium are three fine specimens, two 

 from the Herb. Hillebrand collected by Baldwin and Lydgate, and 

 one collected by Remy ; these with a single imperfect specimen 

 in the Paris Herbarium appear to be the only material acces- 

 sible. The sterile lamina is about 15 by 11 cm., the stem about 

 7 cm. and the petiole of the sterile lamina about 1 1 cm. As it ap- 

 pears to have been rarely collected and little is known of its habit,
