leaves; calyx reddish-brown, with ovate segments; lateral 
staminodia yellowish-white, about as long as the corolla 
segments; lip yellowish-white, spotted with reddish-brown,

Orchidee, A small genus (three species) of stove 
Orchids, with the habit of Habenaria rotundifolia, 
natives of the East Indies. Flowers few in a raceme; 
sepals nearly equal in length, the dorsal one concaye, 
the lateral ones spreading, oblique; petals smaller, nn- 
divided; lip continuous with the column, spreading, 
rather broad, the base produced in a spnr; column yery 
short. Stems having one leaf at the base. For culture, 
see Pogonia,

HEMITELIA. With ver 
require stove temperature, which no doubt accounts for their 
not being more generally cultivated. Most of them are 
strong growers, the trunks in many cases attaining 15ft. 
or more in height; they therefore require large structures 
to enable them to perfectly develop their broad, shining 
fronds, which have an imposing appearance in a fernery 
planted in company with other kinds haying more delicate 
or finely-divided foliage. The beauty of the under-surface 
of the fronds is greatly enhanced by the position of the 
sori, which usually form an almost uninterrupted line 
round the leaflets. 
Hemitelias are not by any means difficult to grow if 
potted or planted in a mixture consisting of about equal 
parts peat, loam, and sand. During the growing season 
they require not only a good deal of heat, but also a 
large amount of moisture at the roots and along their 
trunks, most of which are of a drier and more woody 
nature than those of other Tree-Ferns. 
Propagation is almost invariably from spores, which 
germinate freely, though the plants may also be increased 
by means of lateral offsets, which are occasionally produced 
along the trunks of certain species. Two of the most 
popular kinds are H. capensis (Fig. 444) and H. Smithii 
(Fig. 445). ; 
To the species described on pp. 135-6, Vol. IL., the 
following should be added: 
H. Brunoniana (Brown's). fronds, rachis of pinne often free 
from prickles ; rachis of pinnules beneath more or less erisped- 
pubescent ; veinlets two branicHed very rarely three-branched. 
sori, involucre membranous, reduced before the capsules are 
ripe to a hemispheric cup or sub-patelliform scale.  /. 10ft. 
to 40ft. India. 
H. guianensis (Guiana). A synonym of 7. muiltijlora. 
H. Lindeni (Linden’s), fronds pinnate; pinne shortly stalked, 
thin, 6in. to 12in. long, lin. to ljin. broad, acute, the margins 
cleft into regular, short lobes having their apex directed 
upwards. sori disposed in two or three irregular lines or series 
on the margins of the pinne. Caracas, 1894. 
H. multifiora Parade. /ronds larger than in the type, 
glabrous, bipinnate; rachis wingless, marked with white 
lenticels. sort marginal, copious. Colombia, 1877. Habit more 
robust. (I. H. 1877, t. 280, under name of J. gutanensis 
Parade.)
