“Perianthium quadri-dentatum, tribus minimus, singulari ampliore, produc- 
tiore, rostrum uncinatum efficiente. Ab altero alae latere denticulus unus; leg- 
umen latum, ab altero latere carinatum, ad apicem declinatum, rostratum. 
Semina reniformia, plurima, compressa. Habitat silvis maritimis.” 
Bentham (Mart. Fl. Bras. Addenda 15: 326) guesses Vellozo’s plant to be 
Canavalia gladiata (L.) DC. We can not agree, but think that the plate is a 
fairly good representation of Canavalia brasiliensis Mart. It has nothing at 
all to do with Clitoria brasiliana L., which is Centrosema brasilianum.

In a long discussion Rodrigues compares his plant with C. maritima (C. 
littoralis Vell.) and emphasizes that it is a climber and blooms in February, 
while the seashore plant flowers in August. C. maritima, however, is always 
a climber if it can secure support, as in common cultivation, and as is often 
seen on the coast of Florida. The shape of the leaflets of C. versicolor as fig- 
ured differs from all forms of the variable C. maritima known to the writer, 
which leads us to regard Rodrigues’ species as valid. 
CANAVALIA ENSIFORMIS ALBIDA DC. Prodr. 2: 404. 1825. 
This is based on Mocifio and Sessé’s unpublished plate of a Mexican plant 
and described simply as having the flowers and seeds white. C. ensiformis 
is, in our experience, always a red-flowered plant, but a white-flowered vari- 
ant would not be strange. 
WENDEROTHIA Schlecht. 
DESCRIPTION OF THE GENUS. 
Herbs or shrubs, mostly twining; leaves pinnately trifoliolate; petioles sul- 
cate above; petiolules rather fleshy; stipules caducous, thin, not striate; pe- 
duncles axillary; flowers numerous, in raceme-like thyrses, two or more short 
pedicels often arising from each prominent pedicellar gland; bracts minute, 
caducous; bracteoles mostly orbicular, caducous; calyx tubular-campanulate, 
bilabiate, the upper lip large, entire, the lower small and three-lobed; stand- 
ard large, reflexed, without basal auricles, bearing two callosities toward the 
base; wings free, narrow, auricled; keel falcate, produced or rostrate, some- 
times spirally coiled at tip, the petals partly united; stamens monadelphous,
