two fine spikes; P. Schilleriana alba and P. S. striata, P. Stuartiana var 
nobilis and P. S. punctatissima, P. speciosa vars. Christiana and Imperatrix, 
P. Vallentini, of the Boxallii section; P. tetraspis, P. sumatrana vars 
ochracea and sanguinea, P. x Veitchii and var. brachyodon, P. violacea 
Schroederiana, and the allied Doritis Wightii. 
The Odontoglossums occupy two north houses, and are grown to perfec- 
tion. Raised shades are used to protect them during summer; the floors 
are of cement, and the benches of stone, and water-tight, so as to hold an 
inch of water for evaporation. The following were among the best noted : 
-—QO. x Andersonianum and its varieties Ruckerianum and hebraicum; O. 
cirrhosum Klabochorum, O. Corningianum, O. coronarium, O. crispum, and 
varieties flaveolum (true), Chestertoni, guttatum, Rothschildianum, 
Shuttleworthii, Walkerianum, and virginale, O. Dawsonii, O. Denisoniz, O. 
x elegans, O. Hallii, O. hystrix magnificum, O.lyroglossum, O. mirandum, 
O. X mulus, O. nebulosum, O. nevium, O. Pescatorei Shuttleworthie, O. 
P. roseum, and others; O. polyxanthum, O. prestans, O. preenitens, O. 
purum, O. radiatum, O. ramossissimum, O. Sanderianum, O. x tentacu- 
latum, O. tripudians vars. aureum, O. t. Harryanum, O. triumphans, O. 
Vuylstekianum (type), O. Wallisii, O. x Wilckeanum and var. pallens. 
There are also some very fine specimens of Miltonia vexillaria, two or more 
feet across, with twenty to thirty-five spikes of bloom, and many of the 
growths eighteen inches in height. 
Many other genera might be mentioned, such as Lycaste, Maxillaria, 
Calanthe, Phaius, &c., but the above mentioned will serve to give an idea of 
the extent and richness of the collection.

ONCIDIUM REFRACTUM. 
We have now evidence for the first time of this excessively rare species 
being in cultivation, a plant having just flowered in the collection of M. 
Alfred Van Imschoot, of Gand. It was described by Reichenbach in 1854 
(Bonplandia, ii. p. 12), from specimens collected by Purdie, ten years 
before, at St. Sebastian Nevada, Santa Martha, New Granada. Wagener 
also obtained it at San Pedro, in the province of Ocafia. It belongs to 
Lindley’s group, Microchila exaurita, and is allied to O. zebrinum, Rchb. f. 
Nearly all the species of this group have a straggling inflorescence, and the 
flowers being mostly small, they are chiefly of botanical interest. The 
present species is remarkable for the much reflexed column, and front part 
of the lip. The flowers are light greenish yellow, barred with dusky brown, 
the sepals and petals being undulate and much acuminate. We have no 
record of the introducer of the present species, nor yet how long it has been 
in cultivation.
