b}^ the favors of esteemed correspondents. But as it is quite aston- 

 ishing how rarely the legumes are found in our herbaria, an alterna- 

 tive arrangement based upon the color of the flowers is given for the 

 last nine species. But this I do not regard with favor. 



It is evidently natural and even necessary to retain the primary 

 divisions of simple leaved and trifoliate leaved species, but to these 

 I have added another for B. microphylla^ Nutt., which is intermediate 

 in character. In the Trifoliate it is more convenient to form the 

 principal divisions by bringing together species having bibracteolate 

 pedicels as distinguished from those without them ; and again to sep- 

 arate the latter into those species whose inflorescence is terminal and 

 sometimes leafy, and those in which the racemes are pedicellate and 

 opposite the leaves — a distinction which seems to me to be not only 

 useful but of some importance ; and the latter again by means of the 

 legumes. This arrangement brings the allied species together better 

 than any other that I could think of. If space permitted, the alli- 

 ances of some of the species would present interesting features ; but 

 I will only add that specimens from the South and South-west will 

 still be gratefully received and may serve to illustrate some doubtful 

 forms. 



BAPTISIA, Vent. 



§ SiMPLiciFOLK-E, Leaves all simple; no stipules (stipules and 

 leaflets united). 



1. B. simplicifolia, Croom. Leaves sessile or nearly so; flowers in 

 racemes. Quincy, Florida. 



2. B. pcrfoliata^ R. Brown. Leaves perfoliate ; flowers axillary. 

 South Carolina and Georgia. 



var. lobata. Leaves variously sinuate or lobed or even almost tri- 

 foliate. South Carolina. (Ravenel.) 



§§ Stipulate,. Leaves mostly trifoliate, but some of the upper 

 leaflets and even the conspicuous stipules either suppressed or united 

 together, thus appearing simple and sessile. Flowers in short loose 

 terminal racemes. 



3. B. microphylla, Nuttall. (B. sHpuIacea, Ravenel. I cannot but 

 regret the necessity for the suppression of Ravenel's excellent 

 name.) South Carolina and West Florida to Alabama. 



var. axillaris. Flowers axillary from the upper leaflets. Prob- 

 ably a hybrid. Aiken, South Carolina. (Ravenel.) 



§§§ Trifoliate. Leaves petioled, all trifoliate; flowers in ra 

 cemes.
