Mag. IX. 490. The A. aurantlaca D. Don, Gard. Mag. IX. 622. ; and the A. versicolor R. % P., 

 Gard. Mag. X. 71. If all these be but one, A. versicolor R. % P. is the earliest name, and, con» 

 sequently, that to be preferred. 



Derived from Mr. Low of the Clapton Nursery ; to whom it 

 was imported, from Chiloe, by Mr. Anderson. In habit it 

 approaches A. pulchella ; but probably will always be a much 

 smaller plant. Stems 1^ ft. high. Perianth orange-coloured : 

 segments spreading ; the lower and the three outer of a nearly 

 uniform colour, occasionally with one or two deep orange- 

 coloured streaks ; the two others more yellow below the apex, 

 and having many such streaks down to their yellow nectariferous 

 bases. (Bot. Mag., Sept.) 



CCXL. Orchidea. Dr. Lindley and Mr. Allan Cunningham 

 (whom he quotes) have given, in the Botanical Register for 

 Sept., t. 1699., some suggestions incentive to the more success- 

 ful cultivation of such exotic species of Orchideas, whether epi- 

 phytal or otherwise, as require the stove and green-house in 

 Britain. The spirit of the remarks is, that various species, even 

 in some instances species of the same genus, differ so much in 

 their constitution and native habits, that they will not thrive 

 equally under one common treatment ; and that, consequently, 

 a knowledge of the constitution and native habits of any species, 

 and the causing of the artificial conditions to be as identical as 

 possible with the native ones, are necessary to the successful 

 cultivation of it. 



We quote the given instances of anomalies : — Dendrobium. 

 speciosum languishes in situations where the stanhopeas are in 

 their greatest splendour ; and the Chinese bletias almost perish 

 by the side of Eulophia and Zygopetalum. This arises from 

 the great difference in their respective constitutions, which are 

 each adapted to distinct conditions of life. ... In the genus 

 Oncidium itself, where almost all the species are of tropical 

 habits, O. nubigenum is only found on the cool mountains of 

 Peru, at the height of 14,000 ft.; it will, therefore, require a 

 treatment altogether distinct from that of the mass of the genus. 

 Dendrobium moniliforme and catenatum, again, occur only in 

 Japan, as far north as 37° or 38°, or the parallel of Lisbon, and 

 are periodically subject to a very low temperature. In New 

 South Wales there are two or three species, which grow on 

 trees or rocks, whose natural constitution should suggest to 

 English cultivators of them a mode of treatment different from 

 that uniformly adopted for epiphytes generally in our stoves ; 

 namely, that in which high temperature and considerable humi- 

 dity are employed. Dendrobium se'mulum Br., Cymbidium 

 caniculatum 2?r., Dendrobium undulatum i?r., are three instances. 

 The first is uniformly found upon the rugged trunk of Eucalyp- 

 tus resinifera, or iron-bark tree, in the open very dry forest 

 grounds of the older colony at Port Jackson. The second has
