CYRTOSPERMA (Greek, curved seed). Ardcex. 

 A handsome warmhouse tuberous foliage plant, with 

 large, hastate red-veined leaves resembling an alocasia, 

 but easily distinguished by its spiny stems. 



Herbs with tubers or long rhizomes: If.- and fl.-stalks 

 often spiny or warty: Ivs. hastate or sagittate; petioles 

 long, sheathing at the base. Cyrtosperma has 10-12 

 species, remarkably scattered in the tropics. Cult. 

 presumably same as alocasia. 



J6hnstonii, N. E. Br. (Alocasia Jdhnstonii, Hort.). 

 Tuberous: petiole 2-2% ft. long, olive-green, spotted 

 rose, covered with fleshy, spine-like warts: Ivs. sagit- 

 tate, depressed in the middle, 1^-2 ft. long, olive-green, 

 with prominent and beautiful red veins above. I.H. 

 27:395. G.W. 15, p. 340. Intro, [from the Solomon 

 Isls. as Alocasia Johnstonii, but when it flowered it 

 became evident that the plant is a Cyrtosperma. 



C. ftrox, Lind. & N. E. Br., is a second species of this genus, 

 fagured in I. H. 39: 153, but not known to be in the American trade. 

 It has narrow-sagittate Ivs. on slender, very prickly petioles: spathe 

 rather large, reflexed, greenish white. Borneo. 



GEORGE V. 



CYRTOSTACHYS (Greek for a curved spike). 

 Palmacese, tribe Areceas. Three or four palms of the 

 Malayan region of stately habit, but little known in 

 this country. 



Stem spineless, slender and tall, crowned by a grace- 

 ful cluster of pinnately divided Ivs.: Ifts. narrowly 

 lanceolate, a little oblique, at the apex somewhat bifid : 

 spadix short-peduncled, the branches more or less com- 

 pressed, alternate, sometimes pendulous; fls. monoe- 

 cious, the two kinds in 1 spadix; stamens 6, rarely 12 or 

 15: fr. small, elongate-ovoid, tipped by the persistent 

 stigma. For cult., see Areca. The small and young 

 Ivs. of C. Renda are effective but old plants are not 

 very attractive and scarcely known. G.C. II. 24:362. 



Renda, Blume. Height 25-30 ft. : Ifts. linear or ensi- 

 form, obtuse but somewhat obliquely bifid, delicate 

 gray beneath, the petioles dark, brownish red: spadix 

 3-4 ft. long, the branches nearly alternate, about 18 in. 

 long. Sumatra. Var. Duvivierianum, Pynsert. Lf.- 

 stalks brightly colored. Malay Archipelago. 



Lakka, Becc. Petioles green, not over 4 in. long: Ivs. 

 broad, boldly arched, 33^-4^ ft. long, the Ifts. nearly 

 18 in. long, 1% in. wide, obliquely bifid at the apex, 

 pale beneath. Borneo. N. TAYLOR. 



CYSTACANTHUS (Greek for bladder Acanthus, be- 

 cause the flowers are inflated) . Acanthacese. Evergreen 

 herbs of Burma and Cochin China, with showy, sessile 

 fls. in the axils of bracts, the entire infl. more or less 

 crowded into a terminal panicle or thyrse. Corolla- 

 limb spreading, unequally 5-lobed, the lobes short- 

 rotund; stamens 2; style filiform, the stigma 2-toothed: 

 Ivs. entire: caps, long and narrow, almost 4-sided, many- 

 seeded. Doubtfully distinct from Phlogacanthus. 

 One species is cult. This is C. turgida, Nichols. B.M. 

 6043 (as Meninia turgida). It comes from Cochin 

 China: 2 ft. or less high, with prominently jointed sts. 

 and opposite, elliptic-lanceolate Ivs.: fls. white, yellow 

 in the throat and pink-reticulated on the lobes. April. 

 Cult, as other warmhouse acanthads. (See Aphelandra 

 for example.) Prop, by cuttings of young wood. There 

 are 4 or 5 species of Cystacanthus in farther India. 



CYSTOPTERIS (Greek, bladder-fern). Polypodid- 

 cese. Native ferns, with delicate foliage; deserve to be 

 planted in the hardy fern garden. 



Sori round, covered by a delicate indusium which is 

 attached under one side and opens at the other, becom- 

 ing hood-like in appearance and finally disappearing. 

 The 5 species are native in the north temperate zone. 

 Of easy cult, in shady, rich borders. 



bulbif era, Bernh. Lvs. 8-24 in. long, dark green, 3-5 

 in. wide, widest at the base, long tapering, tripinnatifid, 

 bearing on the under surface of the rachis a series of 

 bulb-like bodies, which germinate and prop, new plants. 

 Canada to N. C. Thrives best on lime-bearing rocks. 

 Exceptionally useful and attractive on damp rocky 

 banks. 



fr&gilis, Bernh. Fig. 1200. Lvs. clustered, gray-green, 

 4-^8 in. long besides the slender stalks, tripinnatifid, 

 widest above the base. Widely distributed over the 

 world at all altitudes. L. M. UNDERWOOD. 



CYTISUS (Greek name for a kind of clover). Legu- 

 minosse. BROOM. Woody subjects, chiefly grown for 

 their profusely produced yellow or sometimes white or 

 purple flowers. 



Mostly low shrubs, rarely small trees: Ivs. trifoliolate, 

 sometimes unifoliolate, rather small, alternate, decidu- 

 ous or persistent, sometimes few and minute and 

 branches almost leafless: fls. papilionaceous, axillary 

 or in terminal heads or racemes, yellow, white or pur- 

 ple; stamens 10, connate; style curved: pod flat, dehis- 

 cent, with few or many seeds; seeds with a callose 

 appendage at the base. About 50 species in S. and 

 Cent. Eu., Canary Isls., N. Afr. and W. Asia. For a 

 monograph of the genus see Briquet, Etude sur les 

 Cytises des Alpes Maritimes (1894).
