ON THE CULTIVATION OF DENDROBIUM.

that are well worth cultivating ; the spikes come out near the top of 
the pseudo bulbs, and opposite the leaves ; it bears only three or four 
leaves at the extremity of the pseudo bulb ; the flowers are yellow, 
but the sepals and petals of a paler colour than the lip, which is 
of a rich yellow ; this requires a rest when done growing ; flowers 
in the early part of the season ; is a native of Nepau.1 ; was 
introduced in 1833 ; and does better in a pot than in a'basket. 
26. Dendrobium sulcatum .—Furrowed. The flowers of this 
are yellow, in spikes like the last, but not quite so large. This 
is an upright growing plant, with from two to three leaves at the 
top of the pseudo : the bulb is compressed and furrowed ; the 
leaves are ovate, and of a dark green ; a handsome species, and 
scarce ; flowers in the autumn : a native of India ; introduced 
in 1837. Does best in a pot ; and requires a cool dry rest. 
27. Dendrobium candidum. —Flowers white. This is a very 
neat species ; a native of the East Indies ; introduced in 1836 ; 
flowers at the beginning of the growing season ; a rare plant; a 
pot or basket does well for it; and it requires a dry and cool rest. 
28. Dendrobium formosum is the most splendid of all the 
species : the sepals and petals are of a yellowish white ; the lip 
is ivory, and very large ; the leaves are ovate and acuminate ; 
hang with the stem or pseudo bulb ; a very scarce plant; does 
best in a basket, as it is a pendent species ; and is a very robust- 
looking plant; requires a dry and cool rest when it has completed 
its growth: a native of the East Indies; introduced in 1837. 
Every person who has a collection, ought to try and get this plant. 
29. Dendrobium aggregatum. —A lovely species, and an abun¬ 
dant flower. When well grown, the spikes will produce as many 
as twenty flowers on each ; and each pseudo bulb will have two 
and three spikes ; and when the plant is large, it will be covered 
with yellow and orange. The sepals and petals are of a bright 
yellow, and the lip is orange ; the flowers are very large ; the 
leaves are thick and rigid, lanceolate, obtuse, or rounded at the 
apex; the pseudo bulbs are small, and only one-leaved. It is not 
like any other Dendrobium, with the exception of Jenkinsii; the 
flowers when first expanded, are very pale, but in a day or two 
will come to their brilliant colour. This is the case with many 
other of the species : a basket or pot suits this best; and it re¬ 
quires a dry rest: a native of the East Indies; introduced in 
1828,
