CELETOSPERMUM 



CHAM^CERASUS 



729 



Chsetospermum bears hard-shelled frs. : Ivs. persist- 

 ent, trifoliate: fls. pentamerous with 10 free stamens; 

 ovary 8-10-celled, with numerous ovules in each cell; 

 cells filled with spongy vesicular tissue; seeds hairy, 

 the cotyledons aerial in germination: first foliage Ivs. 

 opposite. Only one species is known. 



glutindsa, Swingle (Limonia glutinosa, Blanco. 

 jEgle decdndra, .Naves. ^Egle glutindsa, Merrill). TABOG. 

 Fig. 890. Petioles margined; lateral Ifts. small, sessile, 

 scarcely one-third as long as the terminal one; spines 

 slender, straight, sharp, axillary usually in pairs in the 

 axils of the Ivs.: fls. rather large, occurring singly, or 

 in few-fld. clusters on long slender pedicels in the axils 

 of the Ivs.: fr. oblong, 2-3 x l^j in. with a thick 

 leathery rind longitudinally ribbed, 8-10-celled; it con- 

 tains numerous flattened hairy seeds, % to Ain. im- 

 mersed in a watery tissue. Native to the Isl. of Luzon, 

 Philippine Archipelago. 111. Blanco., Fl. Filip. ed. Ill,

 Soc. Bot. Fr. 58, Mem. 8d. pi. 5. The tabog is a 

 rapid-growing tree when young, and in a warm green- 

 house shows a vigorous root-growth. This species is 

 being tested as a stock for use in commercial citriculture. 

 Experiments have shown that oranges, lemons, grape- 

 fruits and kumquats grow well when budded or grafted 

 .on young tabog plants. WALTER T. SWINGLE. 



CHALCAS (from Greek for copper, as the wood has 

 a copper-colored grain). Murrsea of Koenig. Rutdcese. 

 Small spineless trees or shrubs, suggested as a stock for 

 citrus fruits. 



Leaves pinnate, alternate: fls. large, 4-5-merous, 

 solitary or in terminal or axillary cymes; ovary 1-5- 

 celled, with 1 to several ovules : seeds white, woolly or 

 glabrous, cotyledons aerial in germination: first foliage 

 Ivs. opposite. 



exotica, Millsp. (Murrsea exotica, Linn.). ORANGE 

 JESSAMINE. A small tree with pale bark, twigs and 

 petioles usually puberulous: Ivs. pinnate; Ifts. usually 

 5-9, ovate, obtuse or obtusely acuminate, often 

 emarginate, dark green above, paler below: fls. fra- 

 grant, campanulate, 5-parted; petals white; stamens 

 10, free; ovary 2-celled, style deciduous : fr. subglobpse, 

 f-J^in. long, pointed, red. 111. Beddome, Outlines 

 Bot., pi. vii., Wight, Ic., pi. Ind. I, pi. 96. The orange 

 jessamine is commonly grown in greenhouses on ac- 

 count of its abundant and very fragrant fls. These are 

 often to be seen along with the mature red fr., which 

 makes a striking contrast with the panicles of white fls. 

 and delicate foliage. The root-growth of this species 

 is remarkably vigorous under greenhouse conditions. 

 Lemons can be budded on it and make a rapid growth. 

 It is being tested as a stock for the common citrus 

 fruits in situations in which a vigorous root-system 

 is desired. WALTER T. SWINGLE. 



CHAMJEBATIA (Greek, dwarf, and bramble, allud- 

 ing to its bramble-like flowers). Rosacese. A woody 

 plant, grown for its handsome white flowers and for the 

 finely divided aromatic foliage. 



Low shrub, clothed with glandular pubescence: Ivs. 

 alternate, stipulate, tripinnatifid, persistent: fls. in 

 terminal corymbs, white; calyx- tube broadly campanu- 

 late; petals 5; stamens numerous; pistil solitary, with 

 short style and decurrent stigma: fr. a small achene 

 inclosed by the persistent calyx. One species in Calif. 

 Ornamental shrub of agreeable aromatic odor, with 

 graceful foliage and showy white fls. in June and 

 July. It can be grown only in warmer temperate 

 regions, and thrives best in sandy well-drained soil 

 and sunny position. Prop, by seeds sown in spring and 

 by greenwood cuttings under glass. 



folioldsa, Benth. Two to 3 ft.: Ivs. nearly sessile, 

 oval or ovate-oblong, closely tripinnately dissected, 

 1K-2H in. long: fls. white, %in. wide, in 4-8-fld. 



corymbs. B.M. 5171. G. 29:29. B.H. 10, p. 295,

CHAM^BATIARIA (in allusion to the similarity 

 of this plant to Chamsebatia) . Rosacese. Shrub grown 

 for its handsome white flowers and the finely divided 

 foliage; allied to the spireas. 



Deciduous, with glandular aromatic pubescence: 

 Ivs. alternate, bipinnate, with numerous minute segms.; 

 stipules lanceolate, entire: fls. in terminal panicles; 

 calyx turbinate, with 5 erect lobes; petals 5, suborbicu- 

 lar; stamens about 60: carpels 5, connate along the 

 ventral suture, at maturity dehiscent into 2 valves: 

 seeds few, terete, with a simple testa. One species in 

 W. N. Amer. Very similar in general appearance to 

 Chamaebatia, but easily distinguished by the bipin- 

 nate Ivs. and the large dense panicles, and very differ- 

 ent in its floral structure. An upright aromatic shrub 

 with finely cut foliage and white fls. in large terminal

 glutinosa. ( X Yd 



panicles; one of the first shrubs to burst into leaf. It is 

 hardy as far north as Mass., but, like other plants from 

 the same region, it dislikes an excess of moisture, 



Earticularly during the winter, and is likely to be killed 

 y it. It prefers' a sunny position and a well-drained 

 soil, and likes limestone, but grows nearly as well 

 without; it is not a plant for dense shrubberies. 

 Propagated by cuttings of half-ripened wood taken 

 with a heel in August with slight bottom heat; usu- 

 ally by seeds sown in spring, and treated like those of 

 spirea. 



Millefdlium, Maxim. (Spiraea Millefdlium, Torr. 

 Sorbaria Millefdlium, Focke). Shrub, to 3 ft., glandu- 

 lar-pubescent: Ivs. bipinnate, short-stalked, ovate- 

 oblong to linear-oblong in outline, 2-3 in. long, primary 

 segms. linear, deeply pinnatifid, with closely set 

 obtuse lobes about a line long: fls. white, ^T-%IO.. 

 across, short-pedicelled, in terminal panicles 3-6 m. 

 long: carpels hairy. Calif, to Wyo. and Ariz. B.M.
