thinly shaded. For a few days after re-potting, until they have made plenty 
of roots, afford water sparingly... The foliage should be syringed whilst the 
plants are growing actively, as Thunias are subject to attacks of red spider’, 
insects. 
EPIDENDRUM. Plants of Epidendrum vitellinum are developing fresh 
roots and any necessary re-potting should be attended to. This Orchid 
_ resents frequent root disturbance. Therefore any plants that are growing 
in pots sufficiently large to accommodate the new pseudo-bulbs, may remain 
in the same receptacle for another season, providing the compost is not 
impoverished and sour. Newly potted plants should be watered sparingly 
until after the young growths are two or three inches high, when moisture: 
should be applied liberally until the new pseudo-bulbs are completed. This: 
species grows well in a light position in the cool house. 
-Epidendrums of the radicans section, E. O’Brienanum, E. Burtonii, and 
E. Boundii, are rooting freely. Plants that have become unsightly and 
require repotting should be attended to at once. These plants, if 
neglected, will grow to a great length, and become unsightly, but may be 
kept dwarf and compact by proper attention. Straggling specimens should. 
be cut through the pseudo-bulbs to a desired length below some of the aerial 
roots. The stems may be potted singly, or several may be placed together 
to form specimens. The lower parts of the pseudo-bulbs from which the 
tops have been removed may be left in their old pots. They will soom 
start growing afresh, and, when the roots are active, may be re-potted. 
EPIPHRONITIS VEITCHII. This pretty bigeneric hybrid, raised from 
Sophronitis grandiflora crossed with E. radicans is very similar in habit to 
its second-named parent, excepting that the influence of Sophronitis has: 
somewhat dwarfed its growth. Like E. radicans this hybrid is continually 
pushing roots from the stem and should be dealt with as recommended for 
that.species.

LyeasteE.—This American genus contains some most useful and showy 
kinds.. For the most part they are natives of Central America, of easy. 
culture, with showy, long-lasting flowers. Obtained from fairly high. 
altitudes, the cool and intermediate houses suit them best. The plants 
should be potted chiefly in fibre, with a little fibrous loam, well drained and 
liberally watered when growing. Though requiring a rest after growth is: 
completed, they should never be allowed to suffer from want of water. The: 
plants are characterised by stout, ovoid pseudo-bulbs, bearing from one to- 
three plicate leaves. In many of the species, particularly in aromatica, 
Deppei, &c., after the leaves fall, two sharp, thorn-like processes are left on. 
the cicatrice at the top of the bulbs. The flowers are carried singly on.
