DIADELPHIA DECANDRU. 



Root perennial. Ste}n erect or procumbent, scarcely a foot high, and 

 with the whole plant sprinkled with soft hair. Leaves crowded near the 

 summit of the stein, leaflets much dilated in the middle, abruptly arumi- 

 uated, a little scabrous, common petiole 3—4 inches Ion?. Fhtvers in a 

 terminal panicle 1—2 feet long, partial perluncle 2-4 lines long. CaJyx 

 4-toothed, nearly equal in length. Corolla pale violet, nearly white. Pe- 

 ^«/^equal m length. Lo?ncnium 3—4 jointed. Joint, rounded. < 



Ihe stamens m this and the prccecling species are nearly monadel- 

 phous. Tins species is generally considered as tiie H. Glutlnosum of Dr. 

 Muhlenberg and W illdenow, if, however, Willdenow is corre.t, in descri- 

 bing the panicle as arising from tlie base of the stem, which he has twice 

 inentioned, the tvyo species must be distinct. In a specimen of the H. 

 Clutuiosum, winch was sent me by Dr. Muhlenberg, the leaves and pani- 

 cle are unfortunately detached from the stem, as far, however, as thej can 

 be compared to this species, the resemblance is minutely exact.
