306 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Under the name of Dalea diffusa have been aggregated many of the species with 
pediceled flowers, including such very distinct types as D. nutans, D. submontana, ete. 
| have examined much herbarium material labeled D. diffusa, but very little if any 
of it seems typical. With Moricand’s good figure as a guide this species ought some 
time to be clearly made out. 
Parosela nutans (Cav.) Rose. 
soralea nutans Cav. Te. 8:1, pl. 207. 1794. 
Dalea nutans Willd. Sp. Pl 3: 1339. 1801. 
Parosela minutiflora Rose, sp. nov. 
A delicate erect little annual) much branched, glabrous and somewhat glandular; 
leaflets 6 to 14 pairs, oblong to linear-oblong, 3 to 7 mm. long, truncate or retuse, 
glabrous, glandular on both sides especially at or near the margins; rachis winged 
between the leaflets; stipules scarious, filiform; inflorescence a small raceme of 2 or 
3 flowers, pedicels very distinct; calyx including the lobes 2 mm. long, glabrous, 
angled, bearing large glands between the ribs; keel and wings borne near the middle 
of the stamen tube; stamens 10; style slender; ovary glandular. 
Collected by Mr. C. G. Pringle near Yautepec, Morelos, 1902 (no. 8721). 
A species of the so called P. diffusa group, but quite distinct from any known to 
the writer. 
Parosela submontana Rose, sp. nov. 
Herbaceous and probably an annual, about one meter high with long and slender 
branches, more or less purplish, glabrous; leaves slender; leaflets usually 15 to 20 
pairs, sometimes fewer, glabrous, linear-oblong, the margin somewhat glandular; 
rachis not winged; inflorescence a broad leafy panicle of racemes; racemes elongated; 
somewhat rigid, 8 to 10 cm. long, many-flowered, pedicels very distinct; calyx tube 
glabrous, 2 to 24 mm. long, its teeth ovate, acute, serrulate on the margins; corolla 
violet, 10 to 11 mm. long. 
Sollected by J. N. Rose near Plateado, Zacatecas, September 2, 1897 (no. 2744). 
Other specimens of this species have been seen in herbaria and the species is appar- 
ently common in the Sierra Madre of Northern Mexico. 
The species is clearly of the P. diffusa and P. nutans type, but very distinct from 
either. 
Parosela elongata Rose, sp. nov. 
Perhaps a perennial but lower part of stem not seen; branches elongated, glabrous, 
purplish, glandular; leaflets 3 to 7 pairs, oblong, obtuse, 7 to 12 mm. long, glabrous, 
the margin bearing large glands and the under surface small ones; inflorescence an 
elongated stiff spike-like raceme, often 20 em. long ineluding the pedicel; panicles 
very distinct; calyx strongly 10-angled, glabrous, bearing a row of large glands 
between the ribs, its tube 1.5 mm. long; calyx teeth about as long as the tube, green, 
slightly serrulate; flowers purple; stamens 10. 
Collected by Mr. C. G. Pringle at Jojutla, Morelos, August 30, 1902 (no. 11,365). 
Parosela crenulata (Hook. & Arn.) Rose. 
Dalea crenulata Hook. & Arn. Bot. Beech. 285. 1840. 
D. crenulata, referred in Biologia Centrali-Americana and Kew Index to D. nutans, 
should be restored to specific rank. Hooker and Arnott have well characterized it, 
assigning to it a shrubby habit, purplish stems, short dense racemes, and few leaf- 
lets. To these may be added a terete leaf rachis and serrulate calyx lobes. 
This species has been repeatedly collected in western Mexico in recent years. 
A FASCICLE OF NEW LUPINES. 
Lupinus compactiflorus Rose, sp. nov. 
Perennial, simple, erect, 30 to 40 em. high; pubescence of stems of two kinds, one 
of rather close short hairs, the other of long, more or less spreading hairs; leaflets 8
