1924] Penland,—Notes on North American Scutellarias 73 
represent the range and habit of the variety. E. Hall, no. 458 (P); 
J. Reverchon, nos. 440, 2059, 771 (M) and 2126 (M); G. W. Letterman, 
Texarkana, October 15-24, 1894, and Dallas, August, 1882. 
This form was first given recognition by Dr. Gray as a variety of 
S. integrifolia, but was later raised to specific rank. It is, however, 
merely a variety of S. resinosa. An inspection of the range of S. 
integrifolia shows that it has no representative in Texas except 
var. hispida. Finally, the nutlet of S. brevifolia is an exact duplicate 
of that of S. resinosa. Although with leaves somewhat longer than 
those of the ordinary S. resinosa (about 1 em.) a quirk in the nomen- 
clatorial rules gives to this plant the somewhat paradoxical name of 
S. resinosa, var. brevifolia. Originally connected with S. integrifolia, 
the application of the name was apparent. 
13. S. DRumMonp1 Benth. Fic. 11. Stems many, erect, branching 
at the base, villous-pubescent, mostly 1-2.5 dm. high: leaves slightly 
petioled or subsessile, oblong-ovate or oval, entire, 1-2 cm. long, or 
commonly less, undulate-crenate: calyx villous, frequently tinged 
with purple: corolla short, 8-12 mm. long, bluish purple or violet; 
the lower lip exceeding the upper, flaring, notched, violet-spotted: 
nutlets yellowish to dark brown, or blackish with age, with conical 
or frequently laminate processes.—Lab. Gen. et Sp. 441 (1832-1836). 
—S. Helleri Small, Fl. So. U. S. 1024 (1903).—Mostly on rich plains 
or in open woods throughout Texas, in adjacent Oklahoma and New 
Mexico, and running into Mexico. The following sheets are repre- 
sentative. New Mexico: C. Wright, nos. 1539 and 1540. OKLAHOMA: 
G. W. Stevens, nos. 695 and 1078. Texas: S. M. Tracy, no. 7994; 
G. Thurber, San Antonio, April, 1853; F. Lindheimer, nos. 1095 and 
143; E. Hall, no. 456; B. F. Bush, no. 627; E. J. Palmer, nos. 9685 
(M) and 13482 (M); G. Jermy, no. 101 (M); W. M. Canby, no. 201 (M); 
J. Reverchon, no. 2065 (P); H. A. Pilsbry, New Braunfels, April 
17-19, 1903 (P); A. A. Heller, no. 1503 (P); H. C. Hansen, no. 542 
(M). 
Somewhat variable in the size of respective parts, this species is 
yet constant enough not to warrant any breaking up into subdivisions. 
The shape of the corolla is especially constant. The nutlets serve to 
indicate a connection with the S. nervosa—S. parvula group. 
14. S. CARDIOPHYLLA Engelm. & Gray. Stems slender, upright, 
branching, 3-6 dm. tall, puberulent, often purplish-tinted on the 
lower part: leaves petioled, deltoid or subcordate, mostly obtuse, 
crenate, 1.5-4 cm. long: inflorescence loose, leafy-bracted: corolla 
slender, 12-17 mm. long, blue: crest of calyx commonly purple: 
nutlets black, tuberculate with truncate processes, never merely 
granular as in Š. resinosa.—Pl. Lindh. i. 19 (1845).—Arkansas and 
Texas, on gravelly hillsides or sandy woods. The following sheets
