Cryptocarpus (?) capitatus. A scraggy shrub, 10-15 feet high, 

 with rigid divaricate branches aud branehlets, the younger portions 

 finely pubesceut throughout: leaves alternate, entire, mostly broadly 

 obovate, obtuse or acutish, cuneate at base, 1 or 2 inches long includ- 

 ing the slender petiole (3 to 6 lines long) : peduncles solitary, 

 axillary, naked, becoming 6 to 9 lines long, bearing a globose head 

 (4 to 6 lines broad) of cymosely clustered flowers on very short 

 minutely bracteate pedicels ; involucre none : perianth cream-colored, 

 turbinate-campanulate, very shortly and obtusely 5-toothed, a line 

 lone : stamens 5, distinct, the slender filaments exserted ; anthers 

 rounded : ovary obliquely linear-oblong, acute, shorter than the slen- 

 der included style, attenuate to the base; ovule solitary, sessile, erect; 

 fruit unknown. — A single head of flowers was collected in August, 

 but it appears to be a winter bloomer, as the January specimens show 

 an abundance of imperfectly developed flowers. In most of its char- 

 acters, so far as known, the plant is certainly closely allied to Cryp- 

 tocarpus. The fruit and fuller flowering specimens may, however, 

 modify the reference. Near Guaymas. (6-47.)

Amarantus Palmeri, Watson. Varying in habit from procum- 

 bent or ascending to erect and 5 or G feet high, and in the more or 

 less slender or compact spikes, which are often much elongated. It 

 is one of the commonest plants in Sonora and Lower California 

 after the setting in of the rains, in gardens aud cultivated fields and 

 in all bottom lands. It is valuable as a forage plant, and the seeds 

 are largely gathered and sold in the markets for making bread and 

 "attole." The collection includes numerous forms. (76-78, 127- 

 134, 312, 675, 676, 688.) 



Amarantus Palmeri, Watson, var. (?), with very thin-acarious 

 broad perianth-segments, the midvein scarcely reaching to the apes j 

 seeds rather smaller. — On an island in Guaymas harbor, near salt 

 water, prostrate. (3 11 4-.)
