CENTAUElDIUM. See Xanthisma. 



CENTRADfiNIA ( Greek for toothed gland, alluding to 

 the anther glands). Melastomicece. Four species in 

 Mexico and Central Amer., grown in warmhouses for 

 their showy-colored Ivs. and pretty fls. They are herbs 

 or shrubs, with angled or winged branches, petiolate, 

 opposite lanceolate or ovate-entire, ribbed Ivs., and fls. 

 with 4-lohed calyx, 4 petals, 8 stamens, and a 4-Ioculed 

 ovary. The blossoms are pink or white, in axillary or 

 terminal clusters. Prop, by cuttings. Very showy and 

 desirable plants. Stems often colored. Centradenias 

 like rich leaf-mold with sharp sand, and brisk heat. 

 Give a light but shady position. Strong plants are much 

 benefited by liquid manure, and such applications give 

 better colors in both flowers and fruit. Monogr. by 

 Cogniaux, DC, Monographife Phanerogamarum, 7: 116. 



grandiJoUa, Endl. Branches 4-winged : Ivs. ovate- 

 lanceolate, strongly 3-nerved, brilliant red beneath, 

 long-pointed and curving at the end: cymes many-fld., 

 shorter than the Ivs., the fls. light rose, rotate, the 

 petals very obtuse, the stamens unequal. B.M. 5228.— 

 The plantgrows 2 ft. high, and blooms in winter. Very 

 showy. The cut branches hold their color a long time, 

 making the plant useful for decorations. 



floribunda. Planch. Branches obscurely angled, pu- 

 bescent, red: Ivs. narrow-lanceolate, tapering below, 3- 

 nerved, red-nerved below : fls. pink, in terminal pani- 

 cles. F.S. 5:453.-Smaller than C. grandifolia. 



inaequilateraiis, G. Don ( C. rosea, Lindl. ) . Lvs. ovate- 

 lanceolate, unequal-sided, entire, ciliate. reddish be- 

 neath: fls. pink, in terminal corymbose racemes: dwarf. 

 Mex. B.R, 29:20. l. h. B. and H. A. Siebkecht. 



CEHTRANTHUS {Greek, spurred flower). Vaterian- 

 etcew. A few annual and perennial herbs of the Medi- 

 terranean region, with dense clusters of small red or 

 white fls. terminating the branches, and opposite entire 

 or cut lvs.: calyx cut into 5-15 narrow divisions, en- 

 larging after flowering; corolla slender-tubed, 5-parted, 

 spurred at the base; stamen 1: fls. with a pappus-like 

 crest. Of easiest culture. 



rilber, DC. Red Valerian. Jupiter's Beard. Per- 

 ennial, 1-3 ft., smooth and glaucous, forming a compact 

 and floriferous, bushy plant : lvs. ovate to lanceolate, 

 some of them toothed at base: fls. very numerous, deep 

 crimson.— A very handsome old garden plant, too much 

 neglected. It blooms all summer. Excellent for cut- 

 ting. Increased by division; also by seeds. There is a 

 white-fld. form (var. dlhiis). 



macroBiphon, Boiss. Annual, of easy culture in any 

 good soil: 1-2 ft.: lvs. ovate, glaucous, toothed: fls. 

 larger than in the last, red. Spain. — There are white- 

 fld. (var. dlbtis) and dwarf (var. ninus) forms. Excel- 

 lent for rockeries and borders; also good for lawn vases.

CENTROPOGON (Greek kentron. spur, and pogon, 

 beard, referring to the fringed stigma). Campanu- 

 lilcew. About 36 tropical Amer. sub-shrubs or shrubs, 

 often scandent, with alternate, mostly dentate lvs., and 

 long, tubular fls. which are violet, purple, red, or orange, 

 and usually borne smgly on long peduncles : bracteoles 

 very small or wanting. Warmhouse perennial, prop, by 

 cuttings. 



Lucyanus, Honllet. Height 1-2 ft. : stem somewhat 

 wo.hIv: lvs. short-petioled, finely toothed: fls. rose, win- 

 ter; iiiTiiisiilierical, with lanceolate segments recurved 

 at the tips. K.H. 18G8:290.-Said to be a hybrid of C. 

 fasltiosits and Siphocampi/tus betulceformis, but seems 

 to show little influence of the latter, which has longer 

 petioles and peduncles, more coarsely toothed lvs., 

 longer calj'x-segments, and a yellow-tipped corolla. 



fastubsus, Scheidw. Lvs. peach-like, oblong, acute, 

 bordered with glandular teeth, very glabrous, short- 

 petioled: fls. rose-colored, winter ; calyx hemispherical, 

 with 5 lanceolate, denticulate segments. Mex. R.H.

CENTROSfiMA (Greek, spurred-standard) . Legu- 

 mintsce. Butterfly Pea. Twining herbs (at least 

 those in cult.), with pinnate, .3-7-foliolate lvs., and 

 showy white or reddish fls. in the axils. Fl. papiliona- 

 ceous, the standard spurred on the back, the keel broad, 

 and the style bearded at the apex. Species nearly 40 in 

 tropical Amer. and 2 in U. S. 



Virginianum, Benth. Roughish, climbing, 2-6 ft.: 

 Ifts. ovate to linear, shining, stipitate : fls. 1-4 in the 

 axil, 1 in. long, violet and splashed, showy: pod straight 

 and long-pointed, 4-5 in. long. Md. S., in sandy lands.
