Parosela lasiostoma Rose, sp. nov. 
Annual with long prostrate branches, glabrous and very glandular; leaflets 18 to 
25, glabrous, obtuse or retuse, 2 to 5 min. long, bearing large glands beneath; gland- 
less above; stipules setaceous; peduncles very short; racemes very dense and spike- 
like; pedicels distinct but very short; bracts ovate, glabrous or slightly ciliate; calyx 
2 to 2.5 mm. long, 10-nerved, glabrous without, bearing one or two large glands 
between the ribs; the teeth very short and broad, hairy within; petals purplish;

Collected by C. G. Pringle on chalky bluffs near Tula, Hidalgo, 1902 (no. 8728, 
type) and at Cieneguilla, Oaxaca, November 1, 1894 (no. 4657); and by J. N. Rose 
and Jos. H. Painter at Tequixquiac, Hidalgo, August 30, 1908 (no. 6623). 
The Oaxaca specimen was distributed as Dalea nutans, from which it must be quite 
different. 
Parosela radicans (8. Wats.) Rose. 
Dalea radicans S. Wats. Proc. Am. Acad. 1'7: 341. 1882. 
Parosela divaricata (Benth.) Rose. 
Dalea diraricata Benth. Bot. Sulph. 12, 1843. 
Parosela minor Rose, sp. nov. 
Perennial, probably procumbent, branched at base and with long slender stems, 
glabrous; leaflets 10 to 20 pairs, glabrous, oblong, 4 mm. long, rounded or retuse at 
apex, thin, glandular beneath; inflorescence a slender many-flowered, spike-like 
raceme, including the petiole 6 to 10 em. long; bracts linear, shorter than the calyx; 
calyx turbinate, strongly 10-angled, glabrous, glandular above; the lobes lance eolate, 
acute, a little shorter than the tube, hairy on theinner face and margins; corolla violet. 
Collected by Dr. I. Palmer at Lodiego, Sinaloa, October 9 to 15, 1891 (no. 1624). 
Perhaps most closely related to P. anthonyi of Lower California, but with glabrous 
leaves, different calyx, ete. It differs from 2. palmeri in its larger and glabrous 
calyx tube, ete.
