92 SYSTEMATIC ARRANGEMENT OE THE SPECIES 
C. Rogovitschiana, Traut. Mel. Biol. II. Mart. 1855, ex descr.—Flowers 1-1J lines long, usually 4-parted or 
4- and 5-parted in the same specimen, only partially glandulous, or entirely destitute of glands ; scales very small, 
bifid, or commonly consisting of small lateral teeth, or sometimes almost abortive. On the lower Wolga, Liemaschko! 
227; Becker! Kiew, Trautvetter ; Constantinople, Boissier! Greece, Zuccarini! Berger! Dalmatia, Stalio! Alex¬ 
ander! Naples, Gussone! Capua, abundant in fields of hemp, Bruni! Syracuse, Insenga! Corsica, Requien! Toulon, 
Quillon! Montferrand, Ramond! Portugal, Weiwitsch! — It is often found in gardens on Basilicum, and is probably 
often propagated and transported with the seeds of that plant. The Basilicum with the parasite is called in the 
gardens about Naples “ basilico con perrucche ; ” just as the old botanists used to call the grapes, to which C. Epi- 
thymum sometimes attaches itself, “uva barbata.” — In France this form has often been named C. Europcea; and 
DesMoulins, Et. p. 67, etc., confounds it with.& suaveolens.

Engelm. C. Cesatiana , Bert.! FI. It. YII. 623. — Flowers 1 \ lines long, 5-parted, without glands ; lobes of corolla 
narrow, longer than the tube ; scales usually exceeding the tube, deeply laciniate and more or less bifid. — Piedmont, 
on Polygonum , Cesati! Cashmere, Jacquemont! 876. —- The strange fact, that exactly the same form should be found a 
native of so widely distant localities, furnishes but another instance of the cosmopolitan habits of this species. — 
Professor Cesati, 1. c., gives the first correct account of the apparent intrastylar dehiscence of the capsule in the 
following words: “ Capsula . . . ob dissepimenti exsiccationem ... hians, . « . hinc capsulam apice dehiscentem 
mentiens 
Yar. g. Cordofana : calyx large, cupulate, longer than the tube of the corolla; its lobes united 
above the middle, somewhat carinate; scales as in var. australis; stamens and style shorter than in any [494 (44)] 
other form of the species. —Fezogl,'Cordofan, Figari! in Hb. Mus. Florent. 
V 40. C. chlorocarpa, Engelm.! in Gray Man. ed. 1 , p. 350 1 ; ed. 2, p. 337. C. Polygonorum , Engelm.! in 
Sill. Journ. XLlII. p. 342, t. 6, f. 26-29 ; DC. Prod. IX. 461, not Cesati. — Along ponds and wet places, mostly on 
different species of Polygonum, and also on other plants of these localities; St. Louis, Missouri, Drummond! Lind- 
heimerl Engelmann! Illinois, Engelmann! Wisconsin, Lapham! Indian country west of Arkansas, Bigelow! eastward 
thus far only in Delaware, Tatnall! —Closely allied to the last species, especially to var. breviflora; the principal 
difference lies in the triangular, acute lobes of calyx and corolla. Flowers usually 4-parted, about 1 line long; scales 
small, bilobed, or oftener consisting of small lateral teeth, —in a specimen from Delaware they are very incomplete, or 
sometimes almost wanting; large ovary filling the shallow tube of the corolla; capsule comparatively large, thin, 
membranaceous, of a greenish yellow color,—whence the name, which I substituted for my former one, referring to 
the plants on which it is often found; this color of the capsule distinguishes it already at a distance from other species 
growing in the same region. Seeds_0.8 line long, oval, compressed, scarcely angled ; transverse hilum rather shorter 
than in the last species. 
{/ 41. C. arvensis, Beyrich! in sched.; Engelm.! in Gray Man. ed. 2, p. 336. — The different varieties of this 
species are characterized by smaller flowers (often less than 1 line long) in more compound clusters, which approach 
in their form to those of the next species; lobes of calyx very obtuse; lobes of corolla almost always longer than the 
tube, acute or usually acuminate, reflexed and with the point indexed; anthers broadly oval or rounded; scales large, 
deeply laciniate-fimbriate, often exceeding the tube ; styles rather slender, as long as ovary or longer ; seeds 0.5-0.7 
line long, oval or rounded, compressed, with a rather short, linear, often oblique hilum. The differences in the shape, 
size, and texture of the calyx constitute the following varieties. 
Yar. a. pentagona. C. pentagona , Engelm.! in Sill. Journ. XLIII. p. 340, t. 6, f. 22-24; DC. Prod. IX. 461. 
C. arvensis , Beyrich! in Hb. C. globularis , Nutt.! in Hb. — Calyx thin and shining; lobes orbicular, as long or longer 
than the shallow tube of the corolla, forming where they join five projecting angles. — Dry barren soil or 
old fields on different Composites or other plants, sometimes also on shrubs ; from Virginia, Rugel! Sulli- [495 (45)] 
vant and Gray! to the Carolinas, Schweinitz! Bose! Beyrich!' Curtis! Ravenel! and to Florida, Rugel!- 
nro. 400, a. and b. 
The western form, with shorter lobes of the less distinctly angled calyx, was formerly distinguished by me as 
var. microcalyx. — In open woods, on dry soil, on Solidago , Aster, Ceanotlius , etc., Illinois, Geyer! Missouri, Trecul! 
Riehl! Nebraska, Hayden! Indian country west of Arkansas, Bigelow!- The latter has often as large a calyx as the 
eastern form. 
Var. /3. verrucosa. C. verrucosa , Engelm.! 1. c. p. 341, t. 6, f. 25 ; DC. Prod. IX. 461. — Calyx shorter than 
the campanulate tube, fleshy and glandular-verrucose. — On dry prairies, often on Petalostemon , but also on other 
prairie plants: Texas, Drummond! III. 247; Lindheimer! 127; Northern Mexico, Berlandierl 2457, to San Luis
