BOTANY. 
HYDROPHYLLACEZ. 
PHACELIA INTEGRIFOLIA, Torr. in Ann. Lyc. New York, 2, p. 222, t. 3. Delaware creek to the 
Pecos; March. Barely commencing to flower. 
Puacetta Popet, (n. sp.; Plate X): vicosely pubescent, hispidulous with spreading hairs ; 
leaves bipinnately parted, or pinnately cut, the circumscription linear-oblong ; segments oblong, 
pinnatifid ; the lobes 5-9, short and obtuse ; spikes corymbose, densely flowered ; segments of 
the calyx spatulate, about half the length of the campanulate corolla, and a little longer than 
the globose capsule ; stamens somewhat exserted. On the Llano Estacado and Pecos, in grav- 
elly soil; March and April. Stem four inches to a foot high from a biennial root, hispid, as 
are the branches, &c., with rather small and weak bristly hairs. Leaves 2-4 inches long ; the 
primary divisions 3-10 lines long, or the lower ones more reduced in size, on the radical leaves 
barely a line or so in length, clothed with a minute and almost viscid pubescence, with stronger 
hairs intermixed ; the lobes oval or oblong, very obtuse, entire or 2-3-toothed, Spikes an inch 
or more in length, not much elongated in fruit, dense; the flowers sessile, or nearly so. Calyx 
viscid-pubescent and hirsute rather than hispid; the segments spatulate, obtuse, a line and a 
half long, little increased in fruit. Corolla apparently white, about five lines in diameter when 
expanded ; the rounded lobes entire or obsoletely crenulate ; the ten appendages at the insertion 
of the filaments reduced to very short and rounded teeth. Filaments naked, at first slightly, 
at length considerably exserted. Style nearly naked. Ovary hirsute-pubescent. Capsule a 
line or a line and a half in diameter. Seeds four, oval, with the inner face strongly bilunate; 
the central keel very prominent. Albumen conformed to the testa. Fruiting specimens of this 
very distinct Phacelia are in Wright’s collection, (No. 1578.) An abundance of flowering spe- 
cimens were gathered by Dr. Garrard, as well as by Captain Pope, whose name we desire the 
species to bear.
