CYRTOPODIUM

CYRTANDRA (name refers to the curved stamens). 

 Gesneridceae. A large group of tropical shrubs and 

 trees, two or three of which are more or less known in 

 cult, for their fls.; akin to Trichosporum (^Eschynan- 

 thus) ; warmhouse subjects. Lvs. opposite, or alternate 

 by failure of one of the pair, membranaceous, or fleshy 

 or leathery: fls. usually white or yellowish, in fascicles, 

 heads or cymes; corolla-tube cylindrical, the limb more 

 or less 2-lipped; perfect stamens 2, and 2 or 3 small 

 staminodia. Nearly 200 species in the 

 islands of the Indian and Pacific oceans 

 and in China. C. pendula, Blume. Short 

 and stout: Ivs. long-petioled, elliptic or 

 lance-elliptic, acute, gray-blotched above: 

 fls. white with brown calyx, 1^ in. long, 

 the corolla inflated, and purple-dotted on 

 lower side. Java. C. Pritchardii, Seem. 

 Lvs. petioled, elliptic, obtusely toothed, 

 acute: fls. small, white, in 3-fld. cymes. Fiji Isls.

CYRTANTHERA: Jacobinia. 



CYRTANTHUS (Greek, curved flowers; from 

 their pendulous habit). Amaryllidaceae. Tender 

 bulbs from South Africa, known only in a few 

 American greenhouses. 



Flowers umbellate, pendulous or erect, usually red 

 or white w r ith green stripes; stamens inserted in the 

 tube of the corolla; ovary 3-celled, crowded with nu- 

 merous ovules, the seeds flat. Species 20. Their cult, 

 is like that of hemanthus and many other bulbs from 

 the same region. They are suitable for pot culture, or 

 for planting put in summer. The following analytical 

 key gives an idea of the group, and its 3 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., l%-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 Y<Z-\ in. long; style not exserted. Cape Colony. B. 

 M. 1133. L.B.C. 10:947. 



BB. Lvs. linear. (Monella.) 

 Mackenii, Hook. f. Bulb \Y 2 in. thick: Ivs. 2-6, 

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

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

 2 in. long; style exserted. Natal. G.C. 1869:641. Gn. 

 50, p. 63. 



AA. Fls. single, or few 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, 1 ft. long: scape 

 slender, 6-9 in. long; fls. 1-3, bright red, 3-4 ^ in. long, 

 wider funnel-shaped than in the 2 preceding species, 

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

 Var. glaucophyllus, Hort. A form with somewhat 

 glaucous foliage and orange-red fls. 



C. Htittonii, Baker, belongs to Cyrtanthus proper, but its lys. 

 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 Col ny. 

 B.M. 7488. Gn. 50:62. C. inxqudlis, O'Brien. Fls. erect, coral- 

 red, borne in umbels on scapes 1 ft. high; upper segms. of perianth 

 overhanging. Cape Colony. G.C. 111.37:261. C. Jimodii, 

 Beauverd. Umbel 6-9-fld. ; fls. cinnabar, yellow at apex, pendulous. 

 Transvaal. N- TAYLOR, f 



CYRTOCARPA (Greek, curved fruit). TAPIRA. 

 Anacardidcese. One or two Mexican trees, one of which 

 bears a small fruit, likened to a cherry by the natives 

 of Lower Calif. 



Leaves alternate, compound: fls. axillary or terminal, 



Eaniculate, polygamous: fr. an oblique drupe, 1 -seeded, 

 qtro. into S. Calif, by Franceschi. Sometimes united 

 with Tapiria (or Tapirira), from which it differs in its 

 straight embryo and other characters. 



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

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

 pinnate; Ifts. 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, inconspicuous, in 

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

 ent; segms. roundish; petals 5, elliptic; stamens 10; 

 style 1 : fr. the size of an olive, edible. Mex. HBK. 6, t.

CYRTOCERAS: lloya. 

 CYRTOCHlLUM: Oncidium. 

 CYRTODEIRA: Episcia. 



CYRTOMIUM (Greek, a bow) . 

 Polypodidceae. Asiatic half-hardy 

 or greenhouse ferns of rigid 

 habit. 



Leaves simply pinnate, anas- 

 tomosing veins and firm indusia 

 fixed by the depressed 

 center. It differs from 

 Polystichum mainly in 

 venation. Three or 

 four species known. 

 Culture as for 

 Polystichum, to 

 which it is closely 

 allied. 



A. Margins of 

 pinnae entire 

 or slightly un- 

 dulate.

 Smith. Fig. 1199. 

 HOLLY FERN. 

 Pinna? glossy, 

 ovate, falcate; the 

 lower rounded or 

 obliquely truncate at the 

 base, 4-6 in. long, 1-2 in. 

 wide. Japan, India. The 

 large thick glossy foliage 

 makes it an excellent fern 

 for decorations. One of 

 the species used in fern- 

 dishes and one of the few 

 species which can be made 

 to thrive under ordinary 

 house conditions. Plants 

 from the temperate parts 

 of Japan will dp well out- 

 of-doors in the northeastern states if given slight winter 



Erotection. For another illustration, see article on 

 irns. C. Butterfieldii, Hprt., is a form of this species 

 differing in having the pinnae deeply serrate. C. Roch- 

 fordianum, Hoft., recently advertised, is a variety of 

 C. falcatum with fimbriated Ifts. Superficially these 

 two forms resemble C. caryotideum somewhat, but the 

 species are entirely distinct. It has begun to replace 

 the original form in the dealers' stocks. 



F6rtunei, J. Smith. Pinnae dull, lanceolate, opaque, 

 2-4 in. long, J^-l in. wide. Japan.

falcatum.

AA. Margins of pinnae toothed or sometimes lobed. 

 caryotideum, J. Smith. Pinnae larger, 5-^7 in. long, 

 1H~*H m - wide, often auricled on both sides at the 

 base, sharply toothed. India. R. C. BENEDICT.! 



CYRTOPERA: Eulophia. 



CYRTOPODIUM (Greek for curved foot, from shape 

 of lip). Orchidaceas. Epiphytes, grown in warmhouses. 



Stems fusiform, bearing plicate Ivs.: scapes radical, 

 bearing numerous fls., pure yellow or spotted with 

 crimson; sepals and petals equal, free; column semi-
