94 DIADELPHIA. DECAXDRIA. 



ventured to consider it a species in the absence of flowers^ 

 it therefore remains to be confirmed in these particulars 

 by some future observer. This species appears to be de- 

 cidedly perennial, and spreads diffusely to a considerable 

 extent'; the petioles, destitute of the long woolly hairs 

 of tlie preceding-, rarely exceed an inch in length, the 

 subulate stipules are only 2 or 3 lines long-, the leaf 

 is attenuated downwards, and arounded at the summit, 

 covered with short and silky hairs, and only about 2 and 

 a half inches long. 



5 other species of this planus exist in Peru, 3 at Monte 

 Video, 6 in the south of Kurope, several of them also 

 common to the Levant, 1 in Ktrypt, 2 of uncertain locality; 

 an entire leaved species at the Cape of Good Hope, not 

 sufficiently distinguished from L. villosus^ but producing 

 a blue flower, and another in Cochinchina. 



493. CROTALARIA. Z.. (Rattle-box.) 

 Vexillum large and cordate; carina acumi- 



natp. Filaments united in one body, with a 

 dorsal fissure. Legnme pedicellate, turgid. 



Herbaceous or shrubby; leaves simple, ternate or rarely 

 digitate; stipules scarcely any, or conspicuous (as in C. 

 saorittaliSf £tc.) and mostly distinct from the petiole: inflo- 

 rescence various, scarcely that of a simple genua, p. j'. flow- 

 ^ers often spiked or racemose, terminal, axillary or oppo- 

 site to the leaves; legume also often short, and 1 or 2 

 seeded, or long and many-seeded. 



Species. 1. CsagittaUs. O 2. parvifora. 3. ovaKs. Pe- 

 rennial, stem hirsute, procumbent; leaves simple, subses- 

 sile, oval; stipules acuminate, decurrent; racemes about 3- 

 flowered opposite the leaves. Hab. In Carolina and Geor- 

 gia; common around Savannah; leaves sometimes desti- 

 tute of stipules, in wliich imperfect state it is described 

 by Mr. Pursh, who does not also appear to have known 

 that it was perennial, and consequently very distinct from 

 the annual C. sajittaliSf with which Michaux associated it. 



This tropical genus of near 60 species is almost exclu- 

 sively indigenous to India and the Cape of Good Hope-
