February; just beginning to blossom. Stems a foot long.

formis, Moricand, Pl. Nouv. Amer. p. 38, t. 25. High and 
dry prairies and sunny declivities, New Braunfels, &c. June, 
August. — Prostrate, in patches, producing very numerous 
slender and branching stems from a perennial and somewhat 
ligneous root. 'These, when young, are beset with long, 
spreading hairs, which are so slender that they often escape 
notice, and are also deciduous from the older stems. Hence 
our Texan plant is doubtless the S. filiformis of Moricand, 
gathered at Tampico by Berlandier. Moricand’s name is a 
little the earlier published; but it appears from Steudel that 
there is a prior S. filiformis of Jacquin, which has been over- 
looked.!

S. fasciculata, Torr. § Gray, Fl. 1, p. 231, which has recently been gathered in 
color, as is also said by Moricand, and the ae tufied stems spring from a stout pe-

Mi CAE igi cd ue A with S. spinosa. Annual? Flowers

shorter, more divaricate, not erect beaks. The seed — through back, not
