472 . ENUMERATION OF LEGUMINOS&A. 
L. Cochinchinensis, (Lonr. Fl. Cochinch. p. 429) has been 
already referred by Wight and Arnott, Fl. Penins. Ind. Or. 
I. p. 187, to Crotalaria retusa, with which plant Loureiro's 
description agrees perfectly. 
L. africanus, (Lour. l. c.) from the East Coast of Africa is 
certainly nota Lupinus, but his description is too short to 
guess at the plant he has so designated, at least, until the 
plants of that country are better known. 
The annual Lupins either indigenous to, or extensively 
cultivated in the Mediterranean region, do not appear to 
extend far enough into the interior from the North Coast of 
Africa, or eastward into Asia, to be included in the present 
paper. . à 
XV. CROTALARIA, Linn. DC.—Chrysocalyx, Guillem. et- 
Perrott.—Clavulium, Desv. 
À very extensive genus, having a very wide range in all 
warm climates, and constantly known by; the beaked carina,* 
combined with the pod always turgid, even when young. 
A few Cape species belonging to the Oliganthe come very 
near to some Lotononides, but even here the line is easily 
drawn, if all species where both characters are combined, are 
retained in Crotalaria, and all those of this set, where either 
the carina is blunt or the pod flat when young, are referred 
to Lotononis. 
The genus has been divided by Endlicher, Gen. Pl. p. 
1262 into five sections, (exclusive of Priotropis and Amphi- 
nomia), according to modifications of the pod, but the diffe- 
rences there given, are in most cases neither so well defined 
nor so conformable to habit as one would be led to suppose 
by examining a few species only of each section, nor have I 
been able to find any other positive character derived from 
the flower or fruit to break up this very natural genus into 
sections. I have therefore endeavoured, after Wight and 
Arnott, to arrange the species into groups only, characterised 
chiefly by the foliage and habit. | 
* The carina in C. purpurea has a short and rather blunt beak ; in all 
the other species I am acquainted with, it is sharply beaked.
