CATALOGUE. _ =e 
Annual, stem erect, smoothish, or with a few scattering hairs; lower leaves 
small, roundish, crenate ; stem-leaves long, petioled, thin, irregularly deeply 
cleft or strongly halbert-shaped; flowers axillary, sky-blue, 4—}' in diam- 
eter (apparently resembling A. parviflora, Cav.). Calyx-lobes twice as long 
as the tube and distinctly bristly hirsute.. Much against my will, I am 
obliged to retain this still as a variety, there being, so far as I can dis- 
cover, little deviation from the typical form save in the size of the flowers. 
Camp Crittenden, Southern Arizona, at 5,200 feet altitude. (666.) 
Var. PARVIFLORA, Gray.—A_ low annual, 3-6’ high, with a few ovate, 
crenate leaves on long petioles, was collected by Dr. Loew at some locality 
in Arizona. (165 a.) 
SpA HEDEREACEA, Torr. (in Pl. Fendl.p.23).—Loew. New Mexico, Utah. 
Sipa Lepmpota, Gray (Pl. Wright. 1, p. 18).—A much-branching, 
prostrate species, from a descending root; leaves petioled, triangular- 
cordate or somewhat hastate (quite variable), at first densely covered with 
a stellate pubescence below and seurfy above; peduncles axillary, bearing a 
single purple flower 8” in diameter. Carpels with a short, obtuse beak. 
Deer Spring, Ariz., 6,000 feet altitude. (188.) 
Sipa Fiuirormis, Moric. var.—Stems thin, wire-like, procumbent or 
ascending, with long white hairs scattered along the stem and on the calyx; 
petioles 3-1’ long; leaves 6-12’ long, lanceolate to oval, usually crenately 
serrate and more or less densely covered on either side with a short, stellate 
pubescence; calyx angular, lobes acuminate, nearly as long as the yellow 
petals; carpels moderately beaked. (665.) Sanoita Valley, Arizona. 
From Camp Bowie, I have a form which is much more hairy, has leaves larger 
in all respects, and almost beakless carpels. (470.) I have a full suite of 
specimens, and am unable to connect these forms. Hence, I believe they 
will, as we know them better, be regarded as distinct. 
SPHARALCEA ACERIFOLIA, Nutt. —‘Minutely roughish-tomentose, with 
a stellate pubescence; leaves 5-lobed, somewhat cordate; the lobes acute, 
toothed, unequally serrate; peduncles aggregated, terminal; carpels 12-14, 
pointless—Stem much branched. Leaves 2-24’ long, and about the same 
in width: petioles about 4 of the length of the lamina. Flowers 3-4 
together at the summit of the branches. Bracteoles linear-lanceolate.
