to grow, for it can be managed successfully in the 

 same greenhouse as the equally popular Cypripe- 

 diurn insigne ; for bouquets, buttonholes, wreaths, 

 etc., cristata, its pure white variety alba, and its 

 Lemon yellow marked form lemoniana, are very 

 suitable, those of the type being quite common in 

 florists' shops during February and March. 



Culture. Being low-growing and shallow-root- 

 ing Orchids, all the Ccelogynes are best grown in 

 pans, rafts, or baskets, where ample drainage can 

 be afforded, and a not too abundant supply of peat, 

 loam, fibre, and sphagnum placed about their 

 roots. Propagation is effected by division of the 

 rhizomes, but whenever a specimen is divided or 

 repotted sufficient room should be allowed for the 



Indian house, in sphagnum and a little peat. The 

 Pleione group require very different treatment, and 

 are referred to under PLEIONE. 



Watering and Syringing. During warm, bright 

 weather Ccelogynes not only need large supplies of 

 water, but they love to be finely sprayed over by 

 means of a syringe : syringing must, however, be 

 discontinued early in the autumn. With the ex- 

 ception of the pretty Indian Crocuses known to 

 most gardeners as Pleiones, but now referred to 

 Coelogyne the members of this genus are ever- 

 green, and at no time of the year should they 

 become dry .at the roots, though it follows that 

 less water is needed when growth has finished for 

 the season than when roots and leaves are in full 

 growth.

CCELOGYNE DAYANA. 



increase of at least a couple of years. Several 

 species that will accommodate themselves to the 

 conditions of the Odontoglossum bouse for the 

 greater part of the year will be most successfully 

 managed if placed in an intermediate -temperature 

 during the growing season ; this applies to asperata 

 and speciosa. Others, like massangeana and 

 dayana both of which have long, depending 

 racemes (those of dayana being sometimes 5' long) 1 

 should be placed in baskets and suspended from 

 the roof in the Cattleya or intermediate house. 

 Few Ccelogynes appreciate great heat, but .there is 

 at least one exception, and that is pandurata, a 

 most distinct and interesting species from Borneo ; 

 it is a strong-growing plant that requires a great 

 deal of raft room and produces handsome, large, 

 pale green flowers, heavily marked on the lip with 

 blauk. This Orchid should be grown in the East

COFFEA. 



Upwards of thirty species are placed in this genus 

 (vrd. Rubiacese). They are tropical, evergreen 

 trees and shrubs, and though not showy are of the 

 greatest value economically. Arabica was at one 

 time the source of much of the coffee of commerce, 

 but liberica has of late years been largely cultivated. 

 The coffee it yields is little, if at all, inferior to the 

 older Arabian coffee, and the plant grows in places 

 where arabica will not ; moreover, it is not so subject 

 to the dreaded fungoid disease. Propagation is by 

 cuttings, which in this country have to be rooted 

 in sand, beneath a bell-glass in heat ; also by seeds. 

 Seedlings are less satisfactory than plants raised 

 from cuttings. Soil, turfy loam and sand. 

 Principal Species : 



liberica, 10' to 16', wh., 



fragrant. 



stenophylla, 10' to 12' ; a 

 valuable coffee yiclder. 

 travaneorensis, 3 to C' f

 both liberica and steno-
