BROADHURST: STRUTHIOPTERIS IN NortH AMERICA 271 
pinnae are sometimes distant. They are like S. pbolypodioides 
in the proportionate length of the lamina and in the more falcate 
pinnae. The other specimens from Grenada fall unquestionably 
into S. polypodioides. 
We find similar intermediate forms in passing northwest from 
Guadeloupe through Porto Rico. One sheet from Porto Rico 
(Hioram 275, Mt. Torresilla, U.S. National Herbarium no. 657235) 
has the texture and the base of S. Plumieri; the other characters 
are all those of 5S. polypodioides. The other (5) specimens from 
Porto Rico are all of the polypodioides type except that none of 
them has black in the rhizome scales. This black median line is 
also lacking in 4 of the 28 Jamaican sheets of S. polypodioides, and 
occasionally so in specimens from Cuba and Mexico.* 
Fée’s description and picture of Lomaria Plumieri can not be 
separated from L. Plumieri Desv., and Fée himself says that his 
figure is given to “complete” Plumier’s figure. Jenman never- 
theless confused Plumieri with exaltata, thus (1) making his 
description of the habit of Plumieri untrue, and (2) leading to 
the establishment of Féei for what he mistakenly considered Fée’s 
Plumieri, the raised-veined form of polypodioides. Christensen 
gives Lomaria divergens Kze. and L. mucronata Fée both as 
synonyms for Plumieri. Neither is synonymous, for L. divergens 
has pinnae with wedge-shaped bases, and L. mucronata is much 
like exalinta in the cutting and the proportions of the lamina and 
the pinnae.
