compact, }-1 inch in diameter ; flowers fully 3 lines long; lobes of calyx and of cylindrical corolla very acute or 
acuminate ; stamens very short; scales much shorter than the tube, in Humboldt’s specimen broadly oval, in others 
narrow ; styles strongly subulate, as long as capsule ; seeds 0.6 lines long.

t the Bridge of Dingle Peru, Alex. Matthews! 661 in Hb. Hooker.— Very nearly allied to the last, dis- 
tinguished by the loose, few-flowered inflorescence, the small and apparently ad purple (a color not noticed in a 
other species) flowers, the triangular, not imbricate, lobes, the short tube of the corolla, and the still more broadly 
subulate styles. By the styles it is distinguished from C. wmbellata, which it otherwise considerably resembles. — 
Flowers 14-1} lines long ; single seeds globose 
§ 2. Obtusilobee. 
Styles slender, usually capillary ; flowers large or small, usually thin and membranaceous; lobes of calyx obtuse 
in all but the last species; corolla short in the three first, long and cylindric with short laciniz in the four last species; 
scales absent in one (the last) species; styles short in the first, very long in the four last species ; capsule opening late, 
and mostly irregularly ; dead corolla enveloping the capsule except in the first species. 
* Flowers short.

Arizona Territory, south of the Gila River, Chs. Wright! Mex. Bound. Survey, 1623 (541), on some 
Nyctaginea, and 1625 (685) on Ambrosia; fl. Sept. — Glomerules 3-4 lines in diameter, often “strung together like 
beads; 6-12 flowers in each glomerule, 1-1} lines long, of thin texture and white color, on short branched pedicels, 
supported by small obtuse bracts; capsule 1 line in diameter, half as much in height, with a very small intrastylar 
opening ; seeds $ line long, oval, strongly verrucose-reticulate, with a short and broad oblique or perpendicular 
hilum. In aspect this plant resembles somewhat C. arvensis, but is abundantly distinct from this and any other 
species.

Hb. Jussieu. Grammica aphylia, Loureiro! Cochin. 171; ed. Willd. I. 212.—A common plant, as it [480 (30)] 
appears, of the tropical regions of Asia and the ideoks southward, especially Ceylon, extending into 
Candahar (Griffith! 685) and China (in Hb. H. B. Petropol.! as “ C. fimbriata, Bunge,” which name seems to be 
hal), characterized by the strongly carinate rather than sulcate lobes of the thereby 5-angled calyx, with five 
secondary angles at the commissnures; scales rather large, deeply laciniate, and not, as Choisy describes and figu 
them, short said adnate below the throat; styles slender; capsule very thin, enveloped and covered by the corolla, 
opening at base rather irregularly and iis. and therefore often termed “ baccate ;” Loureiro himself describes the fruit 
of his genus Grammica as a “ bacca,” though his original specimen in the Hb. of the British Museum shows the cir- 
cumscissile capsule. Flowers 1-1} lines long; seeds 0.5-0.7 lines long, oval; hilum oblique or usually nearly 
perpendicular. — Lamarck’s original specimen, accidentally raised in the ae aes Plantes of Paris, in 1784, ir 
seeds supposed to have come from China, is preserved in Hb. Jussieu in Mus. P 
C. hyalina, Wight, Ic. 1372; Wallich! Cat. 13201, not Roth, is a Saar a this species, with bifid and rather 
small scales. 
A form from the island of Nassibé, near Madagascar, Boivin! in Hb. Vindobon., has also bifid scales, but is dis- 
tinguished from all other varieties by the capsule being exsert above the corolla, and by the large intrastylar aperture. 
ar. 8. caRINATA, C. carinata, R. Brown! Prod. N. Holl. I. 491, from the tropical parts of New Holland, is 
the same species, with more strongly carinate and more obtuse lobes of the calyx, more obtuse laciniz, and almost 
globose anthers.
