experiencing a check. A few early-flowering hybrids are also in bloom. 
Plants of Ccelogyne cristata are now a picture of loveliness, also the 
brilliant Sophronitis grandiflora. Lycaste Skinneri is flowering freely, also 
the beautiful Trichopilia suavis, while Miltonia vexillaria, some of the 
‘Oncidiums, Cymbidium eburneum and Lowianum, and numerous others 
-are rapidly approaching the flowering stage. 
In the Warm house Dendrobium nobile, D. Wardianum, D. x Ains- 
‘worthii, and other hybrids are producing a fine display of bloom, and the 
beautiful D. thyrsiflorum is developing its flower buds. The winter-flowering 
Cypripedes are not yet quite over, while C. Lawrenceanum, barbatum and 
‘others are coming on to take their place, also the charming little species of 
the C. bellatulum group. 
A good dea: of attention will now be required in the matter of shading 
and ventilation, to prevent violent fluctuations of temperature, for the sun 
ds gaining considerable power, yet is often accompanied by cold drying 
winds. The ventilators on the shady side of the house should be chiefly 
utilised, and the pipes should be kept as cool as possible on all bright days. 
A moist genial atmosphere should be maintained by damping down the 
walls, floors and stages as often as necessary. A sharp watch must also be 
‘kept for the appearance of insect pests, and any necessary measures for their 
eradication promptly taken. 
There will be plenty of potting and topdressing to attend to, and it will 
‘be remembered that the proper time for this operation is generally soon 
-after new growth commences and young growths are beginning to push, so 
that they may be able to utilise the new compost at once. For these 
details, however, the amateur is referred to the Calendar of Operations for 
the month. ; 
DENDROBIUM SMILLI& is a rare and interesting Australian Dendrobium 
which was exhibited at the R. H. S. meeting held on March 8th last by Sir 
Jeremiah Colman, Bart., Gatton Park, Reigate (gr. Mr. Collier). It belongs 
to the section Pedilonum, and has rather dense racemes of white flowers, 
tipped with green. It recalls D. secundum in habit, but has much larger 
flowers. The species was described by F. Mueller, about 1867 (Fragm. 
Phytogr. Austral., vi. p. 94), from specimens collected at Rockingham Bay, 
‘Queensland, by Dallachy, and according to Reichenbach appeared in 
cultivation in 1879, having been introduced by Mr. Bull from North 
Australia (Gard. Chron., 1879, i. p. 106). It is well figured by Fitzgerald 
(Austral. Orch., i. pt. 7, t. 2) under the name of Ccelandria Smilliz, that 
author regarding it as distinct from Dendrobium. Messrs. Sander also 
lowered it in 1900, the plant having been introduced by them with other 
Australian Orchids.—R. A. R.
