 base on a petiole about ^ inch long, entire, 2 to 4 inches long ; 

 stipules caducous : spike-like racemes slender, many-flowered, the

 Lake Chapala ; December, 1889 (u. 2442). Flowers fragrant. 



Randia tomentosa. Branchlets armed at the extremity with

Crusea crdciata. Annual ; stem simple, erect, few-jointed,

 brous : leaves narrowly lanceolate, acuminate, 2 to 2i inches long, 

 the uppermost dilated and ciliate at base, as are also the similar but 

 smaller floral bracts : flowers in most of the axils, the very short 

 pedicels subtended by a circle of bristles ; calyx-lobes triangular-

Spermacoce Pringlei. Annual, erect, sparingly branched, 

 about a foot high, glabrous nearly throughout : leaves oblong-ovate, 

 acute, narrowed below to a short petiole, scabrous on the margin,

 flowers very small, in dense axillary clusters : fruit glabrous, less than
