APIOS 



APONOGETON 



311 



t. l-'<Jrtunei t Maxim., is occasionally cult, in Japan for its small, 

 ovate, edible tubers. A.Ci. 13:77. A. Pricedna, Rob., native 

 to Kentucky, may be expected to appear in the trade: root a single 

 large tuber, becoming 6-7 in. diam.: fls. pale rose-color: a vigor- 

 ous climber, first described in 1898 (Bot. Gaz. 25:451, with illus.). 



APIUM: Celery. 



APLECTRUM (Greek, with no spur). Orchidacex. 

 A small orchid, with smallish dull-colored fls. in a 

 raceme, on a leafless scape, which springs from a large 

 corm-like tuber. Single species (or possibly two), in 

 woods in the northern states. 



Flower spurless and sacless; petals and sepals similar, 

 narrow; lip 3-lobed and crested, deflexed; fertile anther 

 1, the pollen-masses 4, smooth and waxy; column free, 

 compressed, the anther borne below the top. 



hyemale, Nutt. (A. spicalum, B. S. P.). PUTTY 

 ROOT. ADAM-AND-EVE. Fig. 234. Sends up a pointed 

 green If. 2-6 in. long, which lasts through the winter, and 

 in spring a stalk about a foot high, bearing a raceme of 

 rather large greenish brown fls., which are succeeded by 

 hanging, oblong-pointed pods (Fig. 234). Hardy. May 

 be grown in rich, loamy borders. Interesting, but not 

 showy. L. H. B. 



APLOPAPPUS (Greek, simple pappus). Syn., 

 Huplopappus. Composite. Herbaceous perennials, 

 .-nine-times offered for the hardy border. 



Leaves mostly stiffish or rigid, alternate: heads 

 radiate, many-fld., the rays pistillate; involucre hemis- 

 pherical, with several series of closely imbricated bracts: 

 pappus simple, of many unequal 

 bristles, the achene short and nar- 

 row. A genus of about 115 species 



bell-shaped, with 5 appendages inside; stamens 5, 

 inserted deep in the corolla, the filaments very short; 

 style 0: seeds silky. Tough perennial herbs, with 

 milky juice, chiefly of north temperate zone, with 

 oblong or ovate, opposite Ivs., milkweed-like fls. in small 

 cymes, and slender follicles or pods. About 25 species, 

 10 native to N. Amer. 



androsaemifolium, Linn. SPREADING DOG-BANE. 

 Three ft. or less high, usually glabrous, the branches 

 spreading: lobes of corolla revolute and tube of corolla 

 longer than the calyx: Ivs. oval or ovate, mucronate, 

 short-petioled : cymes loose, axillary and terminal; fls. 

 bell-like, white or pink. N. N. Amer.; common. B.M. 

 280. Sold by dealers in native plants. Useful for the 

 hardy border as it will stand dry open places. Root 

 used in medicine; sometimes gathered by drug-collec- 

 tors for A. cannabinum, but as its action is different, it 

 should not be substituted. 



cannabinum, Linn. Branches erect or nearly so: 

 lobes of corolla nearly erect, the tube not longer than 

 calyx: Ivs. ovate to lance-oblong, short-petioled: cymes 

 dense; fls. greenish white. Northern states; common. 

 Not known to be in the trade, but likely to be con- 

 founded with the above. Root emetic, cathartic, dia- 

 phoretic, expectorant, and diuretic. The tough fibrous 

 bark of the stalks formerly used by the Indians for 

 making twine. L, jj_ jj_ 



APODOLIRION (Greek combination, footless lily, 

 the peduncles not being evident). Amaryttid&cex. 

 Greenhouse bulbs of S. Afr., of which one or two of the 

 half-dozen species are rarely cult. Bulb tunicated: fl. 

 1, borne or hidden in the bulb-neck in the manner of 



235. Aponogeton distachyus. 



of herbaceous perennials, rarely shrubs, mostly from 

 Calif, and Chile. Fls. yellow, in summer and autumn. 

 Separated only by technical characters from Bigelovia, 

 into which it insensibly grades. (Bigelovia has discoid 

 few-fld. heads and pappus in single row.) The only 3 

 species known to have been in the American trade are 



lanugindsus, Gray. Hardy alpine herb, woolly, 4 in. 

 high, from creeping rootstocks: Ivs. soft, narrowly 

 spatulate, or upper linear, 1-2 in. long: rays 15-20. 

 Mts. of Wash, and Mont. Intro. 1889, by F. H. 

 Ilorsford. 



Parryi, Gray. Alpine herb, 6-18 in. high, green and 

 almost glabrous: Ivs. oblong-obovate, 2-4 in. long: 

 fl.-heads about J^in. high, pale yeEow, the involucral 

 bracts oblong and obtuse; rays 12-20, small and narrow. 

 Suitable for rockwork. 



crdceus, Gray. St. about 1 % ft., erect and stout, and 

 with radical Ivs. a foot or less long: cauline Ivs. ovate- 

 oblong to lanceolate, partly clasping: fls. showy, saf- 

 fron-yellow, the rays about an inch long, the inner 

 involucral bracts ragged. Rocky Mts. June Oct. 



A. ericoldes, Hook. A Arn. Shrub, 2-5 ft. high: Ivs. very nu- 

 merous, filiform, those of the dense fascicles, 2 or 3 lines long: fls. 

 very numerous. G.C.III. 20:301. M- TAYLOR f 



APOCYNUM (Greek for dog-bane). Apocyndcex. 

 DOG-BANE. INDIAN HEMP. Native herbs, sometimes 

 planted in borders. 



Flowers small, the calyx with acute teeth; corolla 



crocus, white or reddish:, Ivs. usually not appearing 

 with the fls., narrow. A. Ettae, Baker, and A. lanceo- 

 latum, Baker, are probably best known as cult, plants. 

 The former has a white, tinged red fl. 3 in. long and 

 crocus-like Ivs.; the latter (Gethyllis lanceolata, Linn. 

 f.) has a much shorter fl., white or whitish, and a 

 solitary lanceolate If. appearing with the fls. The 

 apodolirions are prop, by offsets or seeds. 



APONOGETON (Greek name, referring to its 

 habitat in the water). Aponogetonacese. Aquatics, 

 mostly with flat floating Ivs. and emerging spikes of 

 fls. Includes Ouvirandra. 



Submerged herbs, with tuberous rhizomes and 

 fibrous roots: Ivs. long-stalked, oblong or linear, some- 

 times lacking the parenchyma and having a lattice- 

 like character: fl.-characters those of the family (p. 13). 

 About two dozen species of warm countries, Asian, 

 African and Australian. Krause & Engler, Das Pflan- 

 zenrei'ch, hft. 24 (1906). There are two main species 

 in cult., the aponogeton proper with solid Ivs., and 

 the ouvirandra with open-work Ivs. The former is 

 grown mostly out-of-doors; the latter in warm green- 

 nouses. 



distachyus, Linn. f. CAPE POND-WEED. WATER 

 HAWTHORN (from the fragrance). Fig 235. Fls. in 

 twin spikes on the emersed ends of long scapes, 

 wholly naked, but subtended by a double row of 

 petal-like bracts, very fragrant, with purple anthers:
