ALFRED HERDER.! 



HYPILENE (Greek, to entwine; referring to the 

 fibers of the fruit). Palmacese, tribe Bordssese. Fan- 

 leaved unarmed palms of moderate or tall stature 

 from tropical Africa and Madagascar. 



Caudex robust, cylindrical, ventricose or pear- 

 shaped, simple or forkingly branched: Ivs. terminal, 

 orbicular, pahnate-flabelliform, plicate-multifid ; segms. 

 ensiform, acute or 2-fid, margins induplicate with 

 fibers interposed; rachis short; petiole strongly bicon- 



104 



vex or a trifle flatter above; margins minutely spiny; 

 ligule short, rotund; sheath short, open: fls. dioacious, 

 in relatively deep pits, on the infl., which is partly 

 hidden by the Ivs. About 10 species from Trop. Afr. 

 The Borassus tribe of palms consists of Borassus, 

 Lodoicea, Latania and Hyphsene. In the first two the 

 staminate fls. in the pits of the spadix are numerous; 

 in the last two they are solitary. In the first and 

 fourth there are few stamens; in the second and third 

 the stamens are numerous. 



crinita, Gaertn. (H. natalensis, Kunze). Young 

 fronds 1 to 1J^ ft. long, lanceolate, bi- or trifid at the 

 apex, bright green, clothed on both sides with a white 

 bloom which soon vanishes, plicate, scabrous on the 

 margins and nerves above; petiole sheathed for 1 or 2 

 in., deeply channelled above, rough on the margins: 

 frs. obovate, 2^ in. long, smooth. S. Afr. Cult, out- 

 doors in S. Fla. Does not look at all like Latania. It 

 has long, thick seed-lvs., and, it is said, has withstood 

 the cold in Fla. better than any other palm. It is 

 extremely slow of growth, and cannot be desirable as a 

 house plant. It is probably cult, more in northern con- 

 servatories than in the S. 



H. thebaica, Mart. A showy palm with striking yellow-orange 

 frs.Ts probably a Corvpha. It is little cult, in N. Amer. F.S. 21 : 2152- 

 3. H. ventricdsa,KiTk, is a showy blue-green palm with an immense 

 cluster of Ivs. and a bulging trunk. Congo. Not in cult, in Amer. 



G-C. II. 21=649. N. TAYLOR.! 



HYPOCH(ERIS (old name, of doubtful origin). 

 Composite. Sometimes written with the digraph a?. 

 Perhaps 50 herbs, of the Medit. region, N. Asia and 

 the southern part of S. Amer., allied to Leontodon, 

 scarcely cult. They are annual or perennial, more or 

 less branched, yellow-fld.: Ivs, mostly radical: involucre 

 campanulate, the scales marginless; receptacle with 

 narrow bracts: achenes 10-ribbed, some or all tapering 

 into a beak; pappus of many fine plumose bristles; 

 heads homogamous, the florets ligulate. H. uniflora, 

 Vill. (Achyrophorus helveticus, Scop. & Less.), has been 

 offered in N. Amer.: perennial: radical Ivs. oblong- 

 lanceolate, dentate, hirsute; cauline Ivs. 1-2: st. simple, 

 1-headed or sometimes 2-3-headed under cult.: invo- 

 lucre very hairy: achenes beaked. Mountains of Eu., 

 and useful in alpine- and rock-gardening. L jj j^ 



HYPOCYRTA (name refers to the gibbous or curved 

 beneath corolla-tube). Gesneriacex. Shrubby, erect, 

 creeping or climbing, natives of tropical America of 

 perhaps ten species. They are little known in cultiva- 

 tion; require the handling of Gesneria and similar 

 plants. H. grdcilis, Mast.=Codonanthe gracilis. 



HYPOLEPIS (Greek, a scale underneath). Polypo- 

 diacese. Tropical glasshouse ferns of both hemispheres 

 rarely cult. Allied to Cheilanthes: rhizomes long 

 and creeping, the fronds herbaceous: distinguished 

 particularly by the marginal sori, placed in the 

 sinuses of the If., and covered with the membranous 

 If.-margin. Ten or more species are known. (See p. 

 1215.) 



repens, Presl. Lf.-stalks straw-colored, more or less 

 prickly; If .-blades 3-4 ft. long, quadripinnatifid; lower 

 pinnae 1-2 ft. long, 6-12 in. wide, ovate-acuminate; 

 sori 2-6 to a segm. W. Indies to Brazil. A rather 

 coarse fern, of easy cult., with the general appearance 

 of a cyathea. Like all strong-growing ferns, it requires 

 a large percentage of loam. It likes shade and moisture 

 at all times, and is readily prop, by spores, which it 

 produces in great quantity, being often self-sown. It 

 requires a stove or intermediate temperature.
