ACTINOTUS (from actinotos, furnished with rays. ; re-

lian genus of greenhouse herbaceous perennials. Flowers 
shortly pedicellate, numerously disposed on simple umbels; 
petals none. Leaves alternate, petiolate. They thrive best 
in loam and peat, and are increased by root division and 
seeds. The latter should be raised on a hotbed, in spring, 
and in May the seedlings may be transplanted out in the 
open border in a warm situation, where they will flower and 
seed freely.

ADA (a complimentary name). ORD. Orchidacee. 
A genus of evergreen orchid, very closely allied to Brassia, 
from which it differs chiefly in having the lip parallel with, 
and solidly united to, the base of the column. Some 
authorities now refer the plant to the genus Mesospi- 
nidium. It requires to be potted in peat and sphagnum, 
in equal parts. The drainage must be perfect, and, during 
summer, the water supply profuse. Although in winter 
far less will suffice, the plant should not be allowed 
to become dry—indeed, it must never be “rested.” 
Propagated by divisions as soon as the plant commences 
growth. 
A. aurantiaca (orange).* jl. orange-scarlet, in long terminal 
nodding racemes, each bearing from six to ten blossoms. Its 
elongated petals are streaked with black inside, Winter and

bulbs, which taper upwards. This species lasts a considerable 
time in perfection. See Fig. 25.

Sawifragacee. A small genus of Hydrangea-like greenhouse ~ 
evergreen shrubs, having many flowered terminal corymbs « 
flowers, and opposite, petiolate, oblong-lanceolate, serrated

sand; and cuttings will root readily in a similar compost, 
under a hand glass.
