304 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Parosela delicata Rose, sp. nov. 
Annual; stems erect, very delicate, somewhat branched, glabrous; leaves narrow; 
leaflets 7 to 15 pairs, minute (2 mm. long), narrowly oblong, glabrous, retuse; 
stipules minute; rachis slightly winged; racemes slender, axillary, 3 to 6 em. long 
(including the petiole), 4 to 9-flowered; bracts ovate, glabrous, infolding the flower 
buds, glandular-dotted and glandular-serrate, caducous; pedicels short but distinct 
(L mm. or less long); calyx strongly 5-angled, the angles cinerous-pubescent, the 
spaces between glabrous and bearing a few large brown glands, 5 mm. long, cleft to 
near the middle; lobes ovate, acute, serrulate; corolla purplish, the longer petals 
7 mim. long. 
Collected by C. G. Pringle on dry hills near Iguala, Guerrero, altitude 780 meters, 
September 14, 1900 (no. S442). 
A very delicate little plant suggesting P. dijfusa, but with pubescent calyx, sepals, 
ete., and otherwise very different. 
Parosela palmeri Rose, sp. nov. 
Shrubby, about one meter high with long weak branches, glabrous or nearly so; 
leaflets about 25 pairs, oblong, 2 mm. long, retuse at apex, glabrous, somewhat 
glandular beneath; inflorescence an elongated loose-flowered raceme; rachis and 
bracts glabrous; calyx tube turbinate, strongly 10-angled, pubescent on the angles; 
corolla purplish. 
Collected by Dr. KE. Palmer near Alamos, Sonora, September, [890 (no. 739). 
This species was distributed as Dalea parryi, but although similar in some respects 
it is abundantly distinct. 
Parosela neglecta (Robinson) Rose. 
Dalea neglecta Robinson, Proc. Am. Acad. 29: 329, 1894. 
Parosela procumbens (DC.) Rose. 
Dulea procumbens DC. Prod. 2: 246. 1825. 
Parosela holwayi Rose, sp. noy. 
Probably biennial, but sometimes appearing as though perennial, diffuse and per- 
haps prostrate; branches many, slender, glabrous or slightly hairy towards the tips, 
purplish; leaflets 4 to TL pairs, oblong, glabrous or nearly so, glandless; rachis 
slender, sometimes slightly pubescent; peduncles slender; flowers clustered near the 
top of the peduncle in a head-like cluster, but distinctly pediceled; calyx strongly 
l0-angled, hairy on the angles, bearing one row of glands between every two ribs; 
calyx lobes Lim. long, half as long as the tube, obtuse, green, ciliate; wings obtuse, 
Violet-colored, 4 mim. long; keel violet-colored except a yellow patch on the lower 
side; both wings and keel attached to stamen tube a short distance above its base; 
banner small, mostly yellowish. 
Collected by Kk. W. D. Holway near Iguala, Guerrero, November 3, 1903 (nos. 48, 
type, & 5139) and near Cuantla, Morelos, October 23, 1908 (no. 18). 
This species is perhaps nearest P. procumbens, but certainly very distinct. 
It vives me great pleasure to name this beautiful little Parosela for Mr. Holway, 
not only as a reminder of our association in Mexican work but also in recognition of 
his most unselfish devotion to botanical research.
