In the discussion of tliis species from the outlying basins in south- 

 western Missouri^ I have stated at length uiy reasons for accepting Broun's 

 name as the proper designation of this form, in preference to the name given 

 to the larger form by Germar. The material in the present collections pre- 

 sents a number of fine examples, which I refer to this species, although 

 they show rather less tendency to dissection than appeared in the others. 

 The photographs seen in PI. L, Fig. 5 and Fig. 6, an enlargement of which 

 is given in PI. LI, Fig. a, show undersized specimens of this beautiful spe- 

 cies. As was remarked in the report above mentioned, the form, not rare 

 in America, is quite different from that with long leaves and with nerves 

 not confluent at the base and sparsely forking, figured by Schimper," 

 Coemans and Kickx,^ Weiss,^ von Roehl,^ Renault," and Renault and 

 Zeiller,'' while I have seen but a single specimen, from Ohio, representing- 

 the type of Grermar.^ The plant illustrated by Raciborski" tinder this 

 name would seem to be more closely related to the S. Fontaineamim Miller. 



Splienophyllum inajus is represented in the Lacoe collection in the U. S.
