HIPPEASTRUM 



HIPPEASTRUM 



1493 



AA. Perianth-tube short (usually not more than 1 in. long). 



B. Throat constricted or closed by a neck or collar. 



c. Stigma capitate. 



2. pardinum, Dombr. Bulb globular, 2-3 in. diam., 

 with a short neck: Ivs. 5-7, appearing with the fls. but 

 not fully developed until after the fls. are gone, becom- 

 ing 2 ft. long and 2 in. broad, narrowed to the base: 

 scape nearly terete, \Y^ ft. tall, glaucous, usually bear- 

 ing 2 spotted fls. ; perianth-segms. 4-5 in. long, oblong 

 but much narrowed at the base, acute, greenish yellow 

 and much spotted with red, not striped, the lowest 

 inner segm. narrowest; stamens declined, shorter than 

 the perianth. Peru. B.M. 



5645. G.W. 12, p. 654. A 

 handsome species, with fls. 6-7 

 in. across, offered in the trade, 

 and also a parent in the 

 modern spotted hybrids. 



cc. Stigma S-parted. 



3. Forgetii, Worsley. Differs 

 from H. pardinum in the fls. 

 being only partially striped, 

 unspotted, and with narrower 

 segms.: pedicels somewhat 

 longer (about 3 in.); perianth 

 dull crimson (color of H. ruti- 



lum), the segms. keeled in the lower half, the base 

 green, about 6 in. across; stamens not exserted; 

 stigma 3-lobed. Peru; a recent introduction. 



4. aulicum, Herb. LILY-OF-THE-PALACR. Bulb 

 ovoid, 3-4 in. diam., with a short neck: Ivs. 6-9, 

 1-2 ft. long, 2 in. broad, bright green, the end 

 blunt or nearly so, appearing with the fls. : scape 

 scarcely longer than the Ivs., stout, terete, usually 

 bearing 2 large red fls., of which the segms. are 

 green at the base; segms. 5-6 in. long, the 2 

 upper inner ones much broader than the others, 

 all of them obovate and somewhat pointed; corona 

 in the throat green; stamens shorter then the 

 perianth; filaments red. Brazil. B.M. 3311. B.R. 

 444. Gt. 45, p. 417. Gn.M. 2:225. One of the 

 best, and common in the trade. The form known 

 as var. platypetalum, Lindl., B.R. 1038, with broader 

 petals and more robust habit, is in cult. 



5. Ackermanni, Hort., is a garden hybrid, with 

 large crimson fls., near H. aulicum. The var. 

 pulcherrimum, Hort., with crimson, green-striped 

 fls., is best known. 



6. psittacinum, Herb. Bulb 3-4 in. 

 diam., with a long neck: Ivs. with the 

 fls., 6-8, lightly glaucous, becoming 

 nearly or quite 2 ft. long: scape stout, 

 2-3 ft. tall, bearing a 2-4-fld. umbel; 

 perianth-segms. 4-5 in. long, oblong 

 and acute, undulate, the edge crimson, 



the main part green but crimson-striped ; stamens much 

 shorter than the perianth. S. Brazil. B.R. 199. L.B.C. 

 13:1204. Apparently little known in cult., but it has 

 been a parent in hybridizations. 



BB. Throat not constricted. 



c. Stigma capitate or only obscurely lobed. 



D. Tube of perianth %-l in. long. 



7. equestre, Herb. (Amaryllis equestris, Ait.). 



1839. Hippeastrum vittatum. 



9, p. 368. An old garden species, one of the best for 

 winter and spring blooming. There are several garden 

 forms and hybrids, with larger and better fls. Var. 

 splendens, Truff., R. H. 1895:578 (var. Wdlteri, 

 Wittm., Gt. 44, 1418), is larger in all its parts, fls. red, 

 and the pedicels are longer. Var. fulgidum, Hort. (not 

 H. fulgidum, Herb.), has brilliant orange segms. mar- 

 gined with white. Var. ignescens, Hort., is deep clear 

 scarlet, with white throat and white bars on the segms. 

 Var. major, Hort., has very large, bright orange fls., 

 with a green central star. B.R. 234. H. Roezlii, Regel, 

 H. pyrrochroum, Lem., I.H. 11:420, and H. spathaceum, 

 Sims, B.M. 2315, are regarded by Baker as forms of 



this species. There are double- 



fld. forms. 



8. reticulatum, Herb. Bulb 

 nearly globular, with a short 

 neck: Ivs. appearing with the 

 fls., rather short and broad for 

 the genus, being oblanceolate, 

 1 ft. long and 2 in. broad, thin, 

 and bright green: scape about 

 1 ft. tall, nearly terete, bear- 

 ing 3-6 tesselated or check- 

 ered fls. 4-5 in. across; fls. 

 bright mauve or purple-red, with cross lines and 

 bars of crimson, the segms. obovate and much nar- 

 rowed below; stamens shorter than the perianth, 

 declined. S.Brazil. B.M. 657. R.H. 1912:448. 

 G.W. 5, p. 187. Var. striatifdlium, Baker, has 

 still broader Ivs., with a white keel or stripe. B.M. 

 2113. B.R. 352. G.C. III. 4 :477 Handsome. 

 Blooms normally in late summer. 



9. styldsum, Herb. (Amaryllis maranensis, Ker- 

 Gawl). Bulb globular, 3 in. diam., with a short 

 neck and pale coverings: Ivs. 4-6, mostly appear- 

 ing with the fls., bright green, becoming nearly 2 

 in. wide: scape 1-2 ft., bearing 3-8 light red or 

 flesh-colored fls. 4 in. across; perianth-tube J^in. 

 long; segms. oblong-acute, less than 1 in. wide, 

 tawny pink or flesh-red; stamens somewhat ex- 

 serted, the style much so (whence the specific 

 name). Guiana and Brazil. B.M. 2278. B.R. 719. 

 Apparently not much cult., but it has been a 

 parent of hybrids. Var. nftdum, Worsley. Sta- 

 mens much exserted and spreading. 



DD. Tube mostly very short (or scarcely any). 



10. Reginae, Herb. Bulb globular, 3 in. diam.: 

 Ivs. developing after the fls., 2 ft. long and 1^-2 

 in. broad, green: scape 10-20 in., bearing 1-4 red 



declined fls. ; perianth-segms. 4-5 in. long, 

 obovate and acute, the lowest innermost 

 one narrower, all bright red, a large 

 whitish star in the throat; tube sometimes 

 nearly or quite 1 in. long; stamens shorter 

 than the perianth. Mex. to Peru and 

 Brazil. B.M. 453. An old garden plant, still much 

 cult. There are double-fld. forms: Amaryllis Alberti, 

 Lem., I.H. 13:498, Baker considers to be one of these. 

 H . Grainnse, Melaz., is a hybrid resembling this species 

 (Amaryllis Graveanaf). G.W. 5, p. 187. H. Spectdbile, 

 Hort., is a hybrid near H. Reginae. L.B.C. 159. 



11. Leopoldii, Dombr. Bulb globular, 2-3 in. diam., 

 with short neck: Ivs. with the fls. or nearly so, often 

 2 ft. long: scape stout, 1^-2 ft., nearly terete, bearing

BARBADOS LILY. Bulb globular, 2 in. diam., producing about 2 large; very regular and parti-colored fls., meas- 



offsets freely, with brown scales and a short neck: Ivs. 

 6-8, developing fully after the fls., 12-20 in. long and 



uring 6-7 in. across; perianth-tube without any corona 

 or constriction at the throat; segms. obovate, 2 in.

white, the intermediate part bright red, with a forked 

 white mark at the base of each, and a green-white 

 throat; stamens declined, mostly exceeding the peri- 

 anth, the filaments white; style exserted. Peru. G.C.
