1900 SUPPLEMENT—RECENT INTRODUCTIONS, &C, 425 
HEXADESMIA (from hez, six, a, withont, and 
desmos, a bond or thong; in allusion to the six separated 
pollen masses). Orb. Orchidee. A small genus (four 
or five spee’es) of stove, epiphytal, branched Orchids, 
natives of Mexico, Central America, the West Indies, and’ 
Brazil, allied to Scaphyglottis. Flowers small, fascicled 
or racemose. Leaves fleshy. Three of the species have 
been introduced, but they are seldom seen outside botanical 
collections. 
HEXAGLOTTIS. Including Plantia. Flowers 
yellow, three or four in a cluster; perianth cut down to 
the ovary into six sub-equal, spreading segments, twisting 
spirally as it fades; filaments very short, flattened, con- 
nivyent; panicle having few spicate branches. Leaves 
one or two, linear or nearly terete. Rootstock a tunicated 
corm, 
HEXAMERIA. A synonym of Podochilus (which 
see). 
HEXISIA (from evisoein, to be equal or like; in 
reference to the conformity of the lip with the sepals). 
Syn. Euothonza. Orv. Orchidew. A small genus (three 
or four species) of epiphytal Orchids, inhabiting tropical 
America from Brazil to Mexico. Flowers mediocre ; 
sepals nearly equal, narrow, the dorsal one free, the lateral 
ones produced in a very short chin; petals resembling the 
dorsal sepal; lip erect, connate with the column at base, 
the lateral lobes obscure, the middle one lanceolate, 
spreading, equalling the sepals; column short; pollen 
masses four; racemes terminal, few-flowered; peduncles 
short. Leaves narrow, rather rigid. Only one species is 
known in gardens. For culture, see Ornithidium. 
H. bidentata (two-toothed).* ji. bright scarlet, about Jin. in 
diameter; sepals and petals linear, acute ; lip narrow obovate- 
oblong ; racemes short, arising from the nodes. 7. linear-oblong, 
not longer than the joints. Stems constricted at the nodes, the 
pas lin. to ljin. long. Panama, Colombia, 1887. A pretty 
ittle Orchid. (B. M. 7051.) 
HEXORIMA. A synonym of Streptopus (which 
see). 
HEYMASSOLI. 
see). 
HEYNEA (commemorative of Dr. Heyne, a German 
botanist). Orb. Meliacee. A small genus (two or three 
species) of stove trees or shrubs, restricted to India and 
the Indian Archipelago. Flowers rather small, in terminal 
and axillary, corymbose panicles. Leaflets five to eleven, 
opposite, entire. H. trijuga (B. M. 1733) and H. quin- 
quejuga have been introduced, but are probably lost to 
cultivation. 
HIBISCUS. Including Abelmoschus and Triguera. 
Calyx five-cleft or fiye-toothed ; staminal column truncate 
or five-toothed ; ovary five-celled. 
The varieties of hardy Hibiscuses grow well in ordinary 
garden soil, but prefer one that is sandy, deep, and rich. 
A sunny position is advisable, although not absolutely 
essential to ripen the wood sufficiently to enable them to 
earry a good display of blossom each antumn. Propaga- 
tion may be carried on by means of seeds, and if sown in 
March in light soil and placed in gentle heat, they vege- 
tate freely. Cuttings of the current season’s matured wood 
taken in early autumn and dibbled in sandy soil, and the 
pots plunged in warm bottom-heat and kept close, emit 
roots in about a fortnight. They must be shaded from 
the sun on bright days. Layering about midsummer and 
in early autumn is sometimes practised; and grafting on 
stocks of the type in spring in heat, and treated as 
recommended for the Hamamelis, is also successful.
