176 Robinson and Greennan—New Plants. 
cinereo-pubescente, columna staminea exserta petalorum longi- 
tudinem dimidio excedente, carpellis nigrescentibus vel subni- 
grescentibus superne in medio sulcatis inferne carinatis.—Col- 
lected by C. G. Pringle, on rocky hills bordering Lake Cuitzeo, 
Michoacan, 20 July and 26 October, 1892 (No. 4132). Stem 10 
to 20 feet high, woody, younger branches at the extremities 
covered with a scurfy cinereous pubescence. Leaves membranous, 
green, cordate; palmately 5-lobed, middle lobe longest, serrate, 
pubescent on both surfaces especially the young leaves, length of 
leaves on specimen 3-33 inches, breadth 3-4 inches, petioles 
14-3 inches long covered with cinereous pubescence. Flowers 
axillary, solitary or at the end of the branches somewhat race- 
mose. Bracts strapshaped, half inch long, shorter than the 
sepals. Calyx three-fourths inch long, sepals triangular or ovate, 
acute, inside the margin cinereous-pubescent. Petals convolute, 
22 inches long. Stamineal tube exserted 14 inches. Styles 10, 
capitately stigmatose. Fruiting peduncles straight, stiff, terete, 
generally slightly bent just below the fruit. Carpels 5, black or 
brownish, black on the back, grooved above, the groove gradually 
passing into a ridge below, third inch long. 
This plant was distributed as Malvaviscus acerifolius Pres], 
of which there is a specimen gathered by Henke in Mexico in 
the Herb. Mus. Brit. J. Pringlei differs from M. acerifolius 
Pres], in its leaves, bracts and flowers. The leaves are much 
deeper lobed in the former than in the latter and in MZ. Pringlei 
the bracts are shorter than the calyx and the petals nearly 3 
inches long; in WZ. acerifolius the bracts are the same length as 
the calyx and the petals an inch long. M. Pringlei differs from 
M. cinereus Bak. fil. MS. in the texture of its leaves and its much 
larger flowers. I have named this very showy plant in honor of 
Mr. C. G. Pringle, who has done so much to further our knowl- 
edge of the Mexican flora. 
Lapruamia Toumeyi Robinson and Greenman. Many-branched 
from a knotted woody base, densely glandular-puberulent ; 
branches about 4 inches long, erect, terete, striated, simple or 
again branched, rather cinereous: leaves spatulate, including the 
petioles 3 to 5 lines long, a line to a line and a half broad; entire, 
obtuse, thickish, cinereous; the petiole channelled above; heads 
discoid, 24 to 3 lines high, equally broad, about 35-flowered, 
terminal upon the branchlets, together forming a pyramidal or 
subcorymbous inflorescence; involucral-scales sub-biseriate, nearly 
equal, acute, the outer thickish, carinate, densely puberulent, the 
inner thinner and flatter: pappus of a single awn: tube of the 
corolla glandular-pubescent: achenes compressed, oblong-linear, 
about a line long, puberulent.—Collected by Prof. J. W. Toumey, 
in the Grand Cafion, 12 July, 1892 (No. 645).
