labellum is rounded and toothed with semi-obovate lateral lobes. The sepals and 
petals are white, the lip having a yellow centre. A2. B2. Cl. D1. El. (ed) F4. 
Variety majus. Sepals and petals a more milky white — flower more regularly 
shaped, labellum more deeply coloured—flower lasts better and is larger in size. 
DENDROBIUM LOWII. Native of Borneo. 
A species which somewhat resembles Dend. draconis in habit and form. Stems up 
to about 16 inches in height, erect, the upper part of the stem having a number of 
ovate-oblong leaves with an obliquely-bilobed apex in length about 34 inches by 
about } inch in width. The bases of these leaves sheath the stems, and are covered 
with short black hairs. The racemes come from near the top of the stems, and 
carry from 4 to 6 pale buff-yellow flowers which are somewhat funnel-shaped. 
The petals are rather longer and half as wide again as the sepals. The labellum is 
pale yellow in colour and has six raised purplish lines furnished with brown hairs 
down the centre. It is longer than the petals, the middle lobe being spathulate 
(tongue-shaped) while the side lobes are oblong and somewhat ligulate. Frag- 
rant in middle of day. Al. B1. Cl. D1. E2. (ed) F4. 
DENDROBIUM LUTEOLUM. Native of Lower Burma. 
A pretty species with slender, extended, fusiform stems up to about 2 feet in 
height, the upper parts of which are furnished with ovate-oblong, obtuse, bi- 
lobed leaves i1bout 4 inches long and 1} inches wide. The short racemes come 
from the upper part of the newly matured stems and carry 2-4 flowers. Sepals 
and petals primrose-yellow, the labellum being the same but marked and lined 
with reddish-purple lines. A2. B2. C2. D2. El. (ea) F4. 
Variety chlorocentrum. Sepals and petals pale yellowish green—disk ornamented 
with green hairs. Flowers rather firmer in texture and slightly larger than the 
type. 
DENDROBIUM LYPERANTHIFLORUM. Native of New Guinea. 
A distinctive species with slender, firm, 20-inch stems, evergreen, and with short 
inter-nodes. Leaves are ovate and about 2 inches long. The racemes are short, 
and grow from the lateral nodes on the upper part of the stems. The dorsal sepal 
is hooded, while the lateral sepals are broadly triangular and falcate. The petals 
are narrow, pointed and falcate, the points being deflexed. The labellum is tri- 
lobed, but the lateral lobes are minute while the middle lobe is oblong-rhomboidal 
in shape, the margins having three or four prominent. teeth while the apex is tri- 
angular pointed and sharply deflexed. In colour the flower is white or cream with 
yellow stripes. Flowers in December. A2. B2. C1. D2. El. (eb) F4. 
DENDROBIUM MACCARTHIAE. Native of Ceylon, etc. . 
A magnificent species, but unfortunately difficult to obtain, its exportation from 
Ceylon being prohibited. It has long, pendulous stems, bulbous at the base, terete, 
and with the nodes purplish or crimson spotted. The leaves are scanty andi are 
narrow and pointed and about 4 inches in length. The racemes are short and 
144 .
