('. </.'.';//<. Reichb. f.,a small Japanese species, is offered by 

 importers of Japanese plants. It is the C. cardlophyllum, 

 Franch. & Sav. Fls. very small, not much larger than those of 

 Calypso borealis.C. fasciculatum is offered by importers of 

 Dutch bulbs. The C. fasdculatum, Kellogg, is Californian: 

 2-6 in., bearing a pair of nearly opposite, ovate, somewhat acute 

 Ivs. : fls. solitary or several, greenish, the depressed lip greenish 

 yellow with a purplish margin. OAKES AMES. 



CTBlLLA (after Dominico Cyrillo, professor of medi- 

 cine at Naples, 1734-1799). Cyrillacece. Shrub, rarely 

 tree: Ivs. short-petioled, entire, glabrous, deciduous or 

 nearly persistent: fls. small, white, in narrow slender 

 racemes, 5-merous: fr. a small indehiscent 2-celled cap- 

 sule with 2 seeds. Probably one variable species from 

 N. Carolina to Florida, west to Texas, and in W. India 

 and S. America. Ornamental shrub, rarely cultivated, 

 with handsome bright green foliage, and graceful ra- 

 cemes of white fls., hardy north to New York. 

 Thrives best in humid sandy soil and shady position. 

 Prop, by seeds and cuttings under glass, with slight bot- 

 tom heat. 



racemiflora, Linn. LEATHERWOOD. Shrub, occa- 

 sionally tree to 30 ft. : Ivs. cuneate, oblong or oblanceo- 

 late, usually obtuse, reticulate-veined, 2-3 in. long, 

 bright green, turning orange and scarlet in fall, but in 

 tropical climates evergreen: racemes 4-6 in. long, erect, 

 at length nodding. B.M. 2456. 8.S. 2:51. The variety 

 from W. India has been described as C. Antillana, 

 Michx., and that of Brazil as C. racemifera, Vandelli. 



ALFRED REHDER. 



CYRTANTHUS (Greek, curved flowers; from their 

 pendulous habit). Amarylliddcece. Twenty species of 

 tender bulbs from South Africa, known only in a few 

 American greenhouses. Their culture is presumably 

 like that of many other bulbs from the same region. 

 They are suitable for pot culture, or for planting out in 

 summer. The following analytical key gives an idea of 

 the group, and its three subgenera. 



A. Fls. many in an umbel, pendulous. 

 B. Lvs. strap-shaped. (Cyrtanthus proper.) 



obliquus, Ait. Bulb ovoid, 3-4 in. thick : Ivs. 10-12, 

 strap-shaped, distichous, produced after the fls., 1 %-2 

 ft. long : scape 1-2 ft. long, stout, mottled : fls. 10-12 in 

 an umbel, entirely drooping, odorless, bright red, with 

 more or less yellow, and greenish tips 2-3 in. long; pedi- 

 cels %-\ in. long: style not exserted. Cape Colony. B. 

 M. 1K33. 



BB. Lvs. linear. (Monella.) 



Mickenii, Hook. f. Bulb 1 % in. thick: Ivs. 2-6, ap- 

 pearing with the fls., linear, 1 ft. long: scape slender, 

 slightly glaucous: fls. 4-10 in an umbel, pure white, 

 2 in. long; style ex.serted. Natal. G.C. I. 29:641. Gn. 

 50, p. 63. 



AA. Flu. single, or feiv in an umbel, erect or slightly 



curved downward. (Gastronema.) 

 sanguineus, Hook. Bulb 2 in. thick : Ivs. 3-4, appear- 

 ing with the fls., lanceolate, petioled, 1ft. long: scape 

 slender, 6-9 in. long: fls. 1-3, bright red, 3-4 % in. long, 

 wider funnel-shaped than in the two preceding species, 

 with a throat 1 in. across. Caffraria, Natal. B.M. 5218. 



C. Hiittoni, Baker, belongs to Cyrtanthus proper, but its Ivs. 

 appear with the fls., and it has 6-8 or even 12 pale red fls. about 

 1 in. long, and a much shorter style than in C. obliquus. Cape 

 Colony. B.M. 7488. Gn. 50:1076. W. M. 



CYRTOCARPA (Greek, curved fruit). Anacardiacece. 

 Two Mexican trees, of which one bears a small fruit, 

 likened to a cherry by tin- natives of Lower Calif. In- 

 troduced into S. Calif, by F. Franceschi. Santa Bar- 

 bara. 



procera, HBK. Very tall tree, with slender, terete, 

 dark purplish, resinous branches : Ivs. alternate, odd- 

 pinnate: leaflets 5-7 or 9, oblong, entire, with a very 

 slight silkiness, especially below, very shortly stalked, 

 1 in. or more long, half as wide: fls. white, inconspic- 

 uous, in panicles 1-2 in. long; calyx 5-parted, villous, 

 persistent ; segments roundish ; petals 5, elliptic ; sta- 

 mens 10; style 1: fr. the size of an olive, edible. Mex. 

 HBK. 6, t. 609. 



CYRTOCHlLUM. Referred to Oncidium. 

 CYRTODElRA. See Episcia. 



CYRTdMIUM (Greek, a bow). Polypodiacece. A 

 genus of Asiatic half-hardy or greenhouse ferns of 

 rigid habit, with simply pinnate Ivs., anastomosing 

 veins and firm indusia fixed by the depressed center. 

 Culture as for Polystichum, to which it is closely allied. 



653. Cyrtomium falcatum. 

 (Leaf X Y*.) 



A. Margins of pinnce entire or slightly undulate. 



falcatum, J. Sm. Fig. 653. Pinnae ovate, falcate ; 

 the lower rounded or obliquely truncate at the base, 4-6 

 in. long, 1-2 in. wide. Japan and India. The large thick, 

 glossy foliage makes it an excellent fern for decorations. 



Fortunei, J. Sm. Pinnae lanceolate, opaque, 24 in. 

 long, %-l in. wide. Japan. 



B. Margins of pinnae toothed or sometimes lobed. 



caryotideum, J. Sm. Pinnae larger, 5-7 in. long, \%- 

 2% wide, often auricled on both sides at the base, 

 sharply toothed. India. L. M. UNDERWOOD.
