136 THE ORCHID REVIEW. [May, 1907. 
Oncipi1ums.—In the Cool intermediate house O. Forbesii, O. varicosum, 
and O. crispum will now have their growth well away, and the necessary 
potting should be taken in hand, using a mixture of equal parts of peat and 
sphagnum, mixed with some crocks and sand. Ordinary pots that can be 
suspended are good receptacles, filling them nearly half full with rhizomes, 
removing any old bulbs. They should be grown suspended, and syringed 
freely overhead whilst flowering. 
DENDROBIUM PHALANOPSIS.— When the growths have attained a height 
of about three inches is the season when the necessary potting, or the 
renewal of the surface material, should be done. Sometimes they are ready 
early in May, but frequently June is well in before the growths have got 
away, and it is good policy to wait. I would not advise disturbing them 
unless the compost is in a sour state, but when they are repotted let it be 
well done, so that they will go for at least two seasons. A suitable mixture 
consists of equal parts of good fibrous peat and chopped sphagnum, with 
some sand and small crocks. Ordinary pots are the best receptacles, using 
a drainage of rhizomes over a few crocks. It is desirable that the pots used 
should be as small as possible, according to the size of the plants. Potting 
should be done firmly and the compost kept low enough to allow of a 
surfacing of chopped sphagnum. After potting, water should be carefully — 
given for some time, and just enough to prevent shrivelling will be ample 
till the new roots have well entered the compost, when the supply may 
be increased, and this course continued till the flowering season is over. A 
very light position in the stove temperature should be given them, and I 
have seen some of the best growths made in an ordinary plant stove. The | 
great point. is when once they have made a good start to grow them as 
quickly as possible. This same treatment is very suitable for D. super- 
biens, and D. atroviolaceum, in fact the New Guinea species generally. 
DENDROBIUM FUSIFORME. 
AN interesting and beautiful Queensland Dendrobium has just flowered in 
the collection of Sir Charles Strickland, Bart., Hildenley, Malton, and has _ 
been identified as Dendrobium fusiforme, a species described by F. M. Bailey 
in 1878 (Proc. Linn. Soc. N.S. Wales, ii. p. 277). It is most like a dwarf 
slender form of D. speciosum, but differs in having fusiform pseudobulbs, 
seldom exceeding a foot long, and very slender racemes, six to ten inches 
long, of white or light yellow flowers, with a number of transverse purple 
lines on the lip. It was originally described as D. speciosum var. fusiforme — 
(F. M. Bail. Syn. Queensl. Fl. 509). It is said to be common on the trees 
of the northern coastal scrubs, and was originally collected at Herberton: 
Sir Charles Strickland’s plant was collected in Queensland, and sent home — 
by his son, Mr. W. W. Strickland. A plant flowered with Messrs. B.- S-
