76 BOTANY. 
Calyx cleft to the middle, segments broadly ovate, acute. Corolla an inch 
in diameter; purple (in dried specimens). Carpels pilose, dehiscing on the 
back from the summit to the base."—(T. & G.) Utah. 
SpHARALCEA F'enpieRI, Gray.—San Francisco Mountains, Arizona and 
Utah. Taller, more branching, with larger leaves, and beaked carpels. 
New Mexico.—Forming a transition in some of its forms into the next. 
S. incana vay. dissecta, Gray, now comes here. 
SPHARALCEA ANGUSTIFOLIA, Spach, “var. foltis lanceolatis, inferioribus 
nunc hastato-sub-trilobatis,” Gray.—Sanoita Valley, Arizona. (634.) The 
plant is erect, somewhat branching at the top; flowers arranged in con- 
tracted racemose panicles on the ends of the branches; leaves with the 
characteristic, eroded margins. A showy plant. My specimens were found 
growing in dry lava soil. (Those of Wright came from alluvial soil.) 
SpHzraLcea Emoryi, Torr. (Pl. Wright. 1, p. 21).—Nevada and 
New Mexico. In Benth. and Hook. Genera Plantarum, we find Malvas- 
trum and Spheralcea in different sub tribes and separated by eleven inter- 
polated genera, yet considering the habit of Spheralcea incana, var. dissecta, 
and the resemblance between S. Emoryi and Malvastrum Munroanum, 
coupled with the broader generalization of Bentham and Hooker under 
head of Spheralcea, as to the resemblance in habit, it may well be doubted 
as to whether the genera should not (in part at least) be thrown together. 
Colorado, New Mexico. 
Hisiscus pENupDATuS, Benth. (Bot. Voy. Sulph. p. 7, tab. 3). (8. involu- 
cellatus, Gray, Pl. Wright. 1, p. 22.)—One or two feet high, with a few 
long, thin branches ; leaves distant, 1-2’ long, $—}’ wide, obtuse, irregularly 
crenate serrate, petioles 3-6’ long; petals light purple, 8-10’ long; bracts 
of the involucel setaceous, 9’’ long ; entire plant, except the flower, densely 
covered with a stellate pubescence. (562.) Cienega, Ariz. (near Tucson). 
THURBERIA* THESPESIOIDES, Gray (Pl. Nov. Thurb. p. 308).—Perennial, 
* THURBERIA, Gray (Pl. Nov. Thurb. 308).—Bracteoles 3, cordate. Calyx truncate. Stamineal 
column produced above [almost to the apex] into many filaments. Ovary 3-celled with a few ovules 
[6-8] in each cell; style club-shaped at the apex. [Stigmatose on the three projecting angles.] Capsule 
loculicidal, 3-valved. Seeds obovoid, angular, minutely woolly, without albumen ; embryo conduplicate, 
cotyledons foliaceons, covered with black spots, much folded, almost including the inferior radical.—Tall, 
smooth herbs. Leavesentire or 3-parted. Flowers white or rose colored, solitary on axillary or terminal 
peduncles.—GRayY in BentHam & Hooker, Gen. Pl]. 1, p. 209. For a much more full description, see 
Gray, Pl. Thurb. 1. c., and fora good figure of this, the only species of the genus, see Bot. Mex. Bound. pl. 6.
