LYCORIS 



LYONIA 



AA. Blooming from Sept. to Nov. 

 B. Fls. orange-colored. 



aurea, Herb. (Amaryllis aurea, L'Her. Nerine 

 aurea, Bury). GOLDEN SPIDER LILY. Bulb 2 in. diam.: 

 Ivs. sword-shaped, 6-9 lines wide, glaucous, produced in 

 May. China. B.M. 409. B.R. 611. G.C. III. 17:263; 



2237. Lycoris squamigera. 



18:545; 47:12, 13. Gn. 47:42. Baker says it blooms 

 in Aug. and has bright yellow fls., but the colored 

 plates show orange-colored fls. 



straminea, Lindl., allied to L. aurea, and probably not 

 in commerce: segms. pale straw-color with pink keel 

 and a few scattered red dots: tube very short. China. 



BB. Fls. bright red (a white form). 



radiata, Herb. (Amaryllis radiata, L'Her. Nerine 

 japdnica, Miq.). Bulb globose, 1^4 in. diam.; neck 

 short: Ivs. 5-6, produced in winter, linear: stamens 

 much longer than the perianth-segms. China and 

 Japan. B.R. 596. A.G. 13:211 The perianth-segms. 

 are more recurved than in other species. The tube is 

 very short, while in all the other kinds here described 

 it is Yi\n. or more long. Var. pftmila, Hort., is much 

 dwarfer than the usual forms. Var. alba, Hort. Pure 

 white shaded cream. S. Japan. 



Recent names in horticultural literature are: L. incarn&ta (Spren- 

 ger, Naples). Scape 1-1 % ft., bearing 6-12 fls., which are large and 

 widely expanded, pale flesh-colored or bright rose and fragrant; 

 segms. scarcely undulate, not much reflexed. Cent. China. G.W. 

 10:489. L. Sprengeri, Comes. Fls. rose-pink or purplish rose, on 



long pedicels, without perianth-tube; spathe-valves short, ovate. 

 Probably Japan. G.C. III. 32:suppl. Dec. 27. G.W. 10:489. Al- 

 lied to L. squamigera, but with shorter less pointed spathe-valves; 



Probably Japan. G.C

 perianth-tube Min. long.

 L. H. B.f 



LYGEUM (Greek, lugoein, to bend). Graminex. 

 Spikelets 1-fld., 1 J^-2 in. long, with a hard, curved beak, 

 2-3 together at the summit of the culms, partially in- 

 closed in a foliaceous sheath: sts. slender, wiry, 2-3 ft., 

 from a hard scaly running rootstock: blades involute, 

 flexuous. Species 1, L. Spfirtum, Linn., of arid parts of 

 the Medit. region. This species, together with Stipa 



tenacissima (which see), forms the "Esparto" of com- 

 merce, which comes mostly from Spain and Algeria.

LYGODIUM (Greek, tunning}. Schiz&acese. CLIMB- 

 ING FERNS. A group of ferns with twining vine-like Ivs., 

 with the sporangia borne singly under overlapping 

 scales on the under surface of reduced portions of the 

 If. Some 30 species are known from all parts of the 

 world. They make an especially attractive growth, and 

 do well when allowed to twine on wires or strings in a 

 large conservatory. For cult, see Ferns, p. 1215. 



A. Sterile pinnules palmate. (Native hardy species.) 

 palmatum, Swartz. HARTFORD FERN. Lvs. 2 ft. or 

 more high, twining, bearing pairs of cordate-palmate 

 pinnules lJ^-2 in. long, on short petioles; fertile pin- 

 nules 3-4-pinnatifid, with the ultimate divisions linear. 

 Mass, to Fla. and Tenn. Requires light moist soil and 

 partial shade. 



AA. Sterile pinnules pinnate. (Exotic glasshouse 

 species.) 



scandens, Swartz. Lvs. many feet long; pinnules 4-8 

 in. long, 2-4 in. broad, with a terminal segm. and 4 or 5 

 on each side, which are simple and usually ovate. India 

 and China. Most of the American material cult, under 

 this name belongs to the next species. 



japonicum, Swartz. Fig. 2238. Lvs. many feet long; 

 pinnules 4-8 in. long, nearly as wide, deltoid, with a 

 pinnatifid terminal segm. and 2 or 3 lateral ones on 

 each side, all unequal and the lowest long-stalked and 

 pinnate in the lower part. Japan and the E. Indies. 

 The common species in cult. 



AAA. Sterile pinnules forked. 



circinatum, Swartz (L. dichotomum, Swartz). Pin- 

 nules practically sessile, once forked, the divisions 

 deeply 5-6-lobed, or sometimes forked twice ; the sterile 

 segms. 4-12 in. long, J^-^in. broad, the fertile segms. 

 very much contracted. Malaysia. 



L. M. UNDERWOOD. 



LYONIA (after John Lyon, who introduced many 

 American plants into England; died .before 1818, in 

 Asheville, N. C.). Syn., Xolisma. Ericaceae. Ornamen-

 and dense foliage.
