This Dalea has considerable affinity with the Mexican D. 

 mutabilis, Cav., (Z). bicolor, Willd.); but that has much shorter 

 spikes and a calyx free from those oblong black glands, which 

 are so conspicuous in the present individual. D. Mutisiif 

 Kunth, approaches still nearer to it; only that there the mucro 

 of the bractea, and the teeth of the calyx, are vastly longer, 

 and the leaves are characterised as hairy. D. Onohrychis, 

 again, of De Candolle, a Peruvian plant, has the spikes ovato- 

 cylindrical and villous.

The present plant belongs to a tribe of the extensive genus 

 Astragalus, having the stipules not adnate with the petiole, 

 but united opposite to the leaf at their base; thus being bi- 

 dentate. Of this groupe, three are natives of Peru; A. Gar- 

 ba7icillo, Cav., A. bidentatus, Humb. et Kunth, Nov. Gen. 

 Am. V. 6. t. 584, and A. unifultus, L'Herit. and De Cand. 

 Asti'ag. t. 10. These have a great affinity the one with the 

 other; and the present plant of Mr. Cruckshanks, though 

 not exactly agreeing with any one of them, I dare not con- 

 sider as really disthict, especially from the former of the
