Valerianetta. VALERIAN ACE^E. 45 



# * Indigenous species: corolla white : no corky mass behind fertile cell of the fruit. 

 •I— Fertile cell decidedly larger and broader than the two empty ones, and cross section of the fruit 

 more or less triangular, the empty cells occupying the obtuser angle : tube of the corolla slender, 

 commonly as long as the throat and limb. 



V- chenopodifolia, DC. Stem a foot or two high, with long internodes and few forks : 

 leaves comparatively large (1 to 3 inches long) : glomerate small cymes few and slender- 

 peduncled : bracts broadly lanceolate, narrowly scarious margined when dry : fruit glabrous 

 or minutely pubescent, 2 lines long, ovate-triangular, the cross section triquetrous or more or 

 less rpunded at the sterile angle, two empty cells about as deep but not as broad as the fertile, 

 sometimes confluent into one when old. — Prodr. iv. 629 ; Gray, Proc. Am. Acad. xix. 82, 

 founded on Fedia chenopodifolia, Pursh, Fl. ii. 727, from specimen in herb. Sherard. V. tri-

 grounds, W. New York to Wisconsin, Kentucky, and Virginia. 



V. amarella, Krok. A span or two high, amply corymbosely branched above, bearing 

 numerous and more open cymes : bracts lanceolate-linear, smaE : fruits very small (about 

 half a line long), trigonous-ovate, densely white-hirsute, with rather obtuse lateral angles 

 and that of the empty cells rounded, these decidedly shorter as well as much smaller than 

 the fertile, almost filiform or sometimes almost obliterated. — Monogr. 1. c. 55, t. 2, f. 14 ; 

 Gray, 1. t. Fedia amarella, Lindheimer, ex Engelm. in PI. Lindh. ii. 217. Spec, name from 

 a peculiar bitterness of the herbage. — Low grounds, Texas, Lindheimer, Wright, Hall, Rever- 

 chon, &c. Gibbosity at base of corolla-throat sometimes very prominent and saccate, almost 

 spur-like. 



+- -f— Fertile cell fully as broad as the two introrse and parallel contiguous and more or less 

 inflated empty ones, occupying the whole back of the fruit, apex projecting in a short obtuse 

 tooth of a line long, the cross section quadrate, a conspicuous groove down the anterior face : 

 stem a foot or two high, twice or thrice forked and spreading, the pedunculifonn branchlets 

 bearing one to three glomerate cymes : fruit in same species either pubescent or glabrous. 



V. radiata, Dufr. Fruit ovate-tetragonal, downy-pubescent or sometimes glabrous on one 

 or all sides ; fertile cell oblong-ovate, flattish ; sterile cells as thick as or thicker than the fer- 

 tile, a broad shallow groove between them. — Hist. Valer. 57 ; Krok, 1. c. 64, t. 2, f . 22, not

 gan, Florida, and Texas. Var. leiocarpa is a smooth-fruited form of it. 



V. stenocarpa, Krok. Fruit tetragonal-oblong, commonly glabrous, sometimes pubes- 

 cent; fertile cell oblong, obscurely narrowed upward, flattish and straight, thicker than 

 the linear-oblong approximate sterile cells, and the groove between the latter narrow. —

•)— -)— h— Fertile cell much narrower or smaller than the ampliate empty ones, one-nerved on 

 the back, the fruit of orbicular or round-ovate circumscription, glabrous or with slight sparse 

 pubescence. 



V. W oodsiana, Walp. Habit of V. radiata and V. chenopodifolia. Fruit a line or more 

 long ; fertile cell oblong-ovate or ovate-lanceolate, tipped by a small soft and blunt tooth ; 

 empty cells introrse, either contiguous or somewhat diverging, inflated, with an oblong de- 

 pression in the middle, sometimes an open concavity. — Walp. Eepert. ii. 527 ; Krok, 1. c.

Var. umbilicata, Gray, 1. c. Empty cells ampliate and in age confluent, vesicular by 

 incurvation of circular margin, forming a deep and rounded or obscurely cruciform umbili- 

 cation. — V. umbilicata, Krok, 1. c. 67, t. 3, f. 25. Fedia umbilicata, Sulliv. in Am. Jour.

Var. patellaria, Gray, 1. c. Empty cells divergent and obcompressed-dilated, so 

 that the sterile face becomes open-concave, emarginate at top and bottom, and the whole
