HYPHSENE. (DOOM, DOOM, or GIXGICC- 

 BBBAD PALM.) 



Fan-leaved Palms (ord. Pahnee), needing a stove 

 temperature. Thebaica is the 'principal species 

 in cultivation, and even >this is not' at all common. 

 The stem is noticeable for its brandling habit, 

 quite unique amongst Palms. The wood is very 

 hard, and is employed in Upper Egypt and Nubia 

 for making domestic utensils. Propagation, by 

 seeds, which have to be imported, and are some- 

 times very slow an'd irregular in germination. 

 Soil, loam two parts, well-rotted cow manure one 

 part, and road scrapings one-sixth. 



HYPOCALYMNA. 



Greenhouse evergreen shrubs (ord. Myrtacese). 

 Cuttings of the young shoots may be rooted in 

 spring in a close frame, and the plants do best in 

 loam two parts, peat one part, and sand. 



Principal Species :

HYPOCALYPTUS. 



A genus of three species only (ord. LeguminosEc), 

 several species formerly included in it being now 

 referred to Podalyria. Obcordatus is an ornamental 

 evergreen shrub, that may be increased by cuttings 

 of the side shoots in April in a close frame, without 

 much heat. Soil, peat and loam in equal parts, 

 with one-sixth of sand. 



Principal Species : 



obcordatus, 1' to 2', Je., Jy., grh., pur. (syn. 

 Crotalaria purpurea of Botanical Magazine 3894;. 



HYPOCYRTA. 



Stove shrubs (ord. Gesneraceas), about ten species 

 in all. Not much cultivated. They answer to the 

 same cultural treatment as Gesneras; in brief, 

 propagation by cuttings rooted in heat, and for 

 soil, loam and leaf mould in equal parts, with sand. 



Principal Species : 

 glabra, 8" to 10", Je., 



Jy., sc., yel., stems pur. 



HYPODERRIS. 



A small genus (ord. Filices) of two species 

 of stove Ferns, closely allied to Woodsia. They 

 are of easy culture, may be raised from spores, and 

 like a compost of one part of loam and two parts 

 of sandy peat, with plenty of water during the 

 summer. They like a deeper shade than most 

 Ferns, and do well planted out in the warm fernery. 



Only Species : 



Brownii, fronds 10" to 12" Seemannii, fronds l.Vloug. 

 long, ev. 



HYPOESTES. 



A rather large genus (ord. Acantliacejc) of stove 

 herbaceous perennials and evergreen shrubs, not 

 often grown. They need similar cultural treat- 

 ment to Jacobinias and Justicias. 



Principal Species : 



sanguinolenta, l>" to 12", pale pur., wli., herba- 

 ceous. 



Other Species : 



aristata, 2' to 3', Feb., ro., involucrata, 1.',', Jy.,Aug., 

 pur., herbaceous. wh.

strigillosa, 2', My., sc., 

 yel., solitary. 



HYPOLEPIS. 



Stove and greenhouse Ferns (ord. Filices) closely 

 related to Cheilanthes, but stronger growing, and 

 with creeping rhizomes. The latter afford a capital 

 method of propagation, for very small divisions will 

 grow. Spores also germinate freely, and the plants 

 grow quickly ; indeed, Hypolepises are apt to 

 become weeds in the fernery, and choke up spore- 

 lings of more tender kinds. .Some of the species, 

 notably repens, make elegant basket plants. Soil, 

 loam and leaf mould in equal parts, with sand. Of 

 i.isect pests snowy fly is the worst, and once it 

 gains a footing, it is difficult to get rid of. 



HYFOXIS HEMEROCALLIDEA (see p. 437). 



Principal Species : 



bergiana, fronds 1' to IV 

 long, 0" to a" broad, 

 stems woolly, grh. 



distans, fronds 12" to 15" 

 long, 4" to />" broad, 

 grh., resembles a var. 

 Other Species : 



of Asplenium 

 fcrmiiia. 

 repens, fronds 3' to 4' 

 long, pendent, much 

 cut, st., grh.: good for 

 baskets or rustic work. 



Uypodcmatium 



ania uroraehis, fronds 3' 

 long, 2' broad, grli. 



iiiithiiscifolia (of gar- 

 dens, not anthriscifolia 

 of Preslau), fronds 6" 

 to 7" long, nearly hdy., 



good for baskets ; a 

 pretty, lace-like Fern.

ra'liata (*.'///. Adiantojisis 

 radiata, now Clii'ilan-

HYPOLYTRUM. 



Sedge-like plants (aril. Cyperaceai) of little 

 horticultural value, save the stove species lati- 

 folium. It injiy be propagated by seeds, or by 

 cuttings taken whenever they can be obtained, and 

 it revels in plenty of heat and moisture. Soil, 

 sandy loam and peat in equal parts. All the 

 species of Hypolytrum are tropical or sub-tropical.
