De Candolle reduced this species in an indefinite way to a variety 
of R. copalliza, while Gray * developed this idea and assigned it a 
range from Florida and the West Indies to Texas, but on different 
materal than that under consideration. The discovery of this spe- 
cies in Florida adds another tree to the flora of the North American 
mainland. 
AYENIA EUPHRASIAEFOLIA’ Griseb. 
This apparently very rare Cuban plant occurs in great abundance 
all over the coral-sand rock ridge from Miami southward. Speci- 
mens were collected at different points from the northern end of 
the ridge to near Long Key (mainland) (nos. 704, 849, 928 and 
886). 
AMMANNIA LATIFOLIA L, 
This West Indian plant may now be included in the flora of the 
North American mainland. Specimens were collected several 
years ago at Key Largo by Mr. Pollard (no. 183), but distributed 
under a different name. In November, 1903, Mr. J. J. Carter 
and the writer collected specimens in the everglades between Cutler 
and Camp Longview (no. 997), and about Boca Ratone Lake, 
below Delray (no. 1053). In March, 1rg04, Dr. Britton found 
plants growing at Cape Florida (no. 314). 
TETRAZYGIA BICOLOR (Mill.) Cogn. 
The discovery of this plant in Florida adds another tree to the 
North American mainland flora. This species was first observed in 
the pinelands about eight miles southwest of Cutler by Mr. J. J. 
Carter and the writer on a trip to Camp Longview, November 9g— 
12, 1903 (nos. 994 and 1106). Dr. Britton collected specimens in 
the same region in 1904 (no. 217), while Mr. Wilson and the writer 
found the species on Long Key (mainland) in May, 1904 (no. 
1649), and in hammocks and adjacent pinelands near Camp Long- 
view discovered it growing as a tree sometimes 25 or 30 feet tall 
(nos. 1696 and 1932). 
PASSIFLORA SEXFLORA Juss. 
This interesting passion-flower was found in hammocks near 
the homestead trail between Cutler and Camp Longview by Mr. J 
J. Carter and the writer on an excursion to Camp Longview,
