kable for vigour, and all well set with flower sheaths. In flower were good 
examples of Coelogyne cristata and C. c. Lemomiana; a noble plant of the fine 
white Chysis bractescens, some beautiful forms of Lycaste Skinneri, Cattleya citrina, 
Odontoglossum citrosmum, with many spikes, and several others. 
“ In the third division, the collection of Cypripediums, Phalaenopsis, Angrae- 
cums, Vandas, Dendrobiums, etc., were in fine condition, with some in bloom, 
among which we noted Phalaenopsis Stuartiana, P. Schilleriana, Dendrobium nobile, 
and a plant of Aganisia cyanea, with its large sky-blue flowers, which last, being 
a difficult plant to manage successfully, bespeaks the Doctor's skill in Orchid 
culture, for he manages the plants himself. ”

them in pots. Besides which these plants do not generally attain such a size as 
Vandas, and their repotting therefore does not present any difficulty.

The propagation of caulescent Orchids, of which we now come to speak, 
may be effected very easily by sections of the stem. It is better, and more 
convenient, to select a piece furnished with roots. The. section should be made 
a short distance below a root, and the cut part should then be dusted with a 
little powdered wood charcoal to make it heal. The piece should then be potted 
in the ordinary way, and be placed for some time in a shady spot. The plant 
thus deprived of its apex will soon grow again, by producing lateral growths. 
The lateral growths which are produced from the base, or at various heights 
along the stem, may also be propagated in the same way. 
Fragments of stem not furnished with roots may also be propagated, if 
potted and placed in a shady house, in a warm and very humid atmosphere. 
The cutting may also be placed under bell-glasses in a thick bed of sphagnum 
moss. The roots will appear later, and the plants may then be potted and placed 
under ordinary conditions.
