itself chiefly to trees.* It was dedicated by Beichenbach as a 

 distinct species to the late Mr. James Veitch.f 



Cultural Note. — D'endrobium Infimdibulum and its variety are, botani- 

 cally, nothing more than alpine forms of D. formosum, and they therefore 

 require a cultural treatment consonant with the higher altitude and 

 corresponding lower temperature in which they grow in their native 

 country. The conditions most suitable for them in the orchid houses of 

 Europe are found to be best fulfilled either in the coolest and lightest 

 part of the intermediate or Cattleya house, or still better in the Odonto- 

 glossum house, which many cultivators prefer ; a moist atmosphere is 

 also essential during their growing season. 



D. Japonicum. 



Eudbndrobium — Fasciculata. Stems tufted, 6—12 inches long, slender, 



attenuated downwards. Leaves lineardanceolate, acute, 1 — 2 inches 



long, deciduous. Flowers fragrant, 1J inches in diameter, solitary or 



in pairs, white, speckled with purple at the base of the lip ; sepals 



oblong, acute ; petals similar but broader ; lip ovate-oblong, acuminate, 



reflexed.

 5482. Onychium japonicum, Blume, Bijdr. 328. 



A species with small, white, fragrant flowers, .common throughout 



southern Japan, especially in the Oki group of islets, and .the 



islands in the Corean Channel. It has been in cultivation since 



1860. 



D. Jenkinsii. 



Stachyobium — Speciosce. A dwarf tufted plant. Stems pseudo-bulbous, 



much crowded, ovoid, compressed, with a rib on the flattened sides, f — 1| 



inches long, monophyllous. Leaves oval-oblong, an inch long, leathery. 



Flowers large for the size of the plant, usually solitary on filiform 



peduncles, \\ inches long, orange-yellow with the disc of the lip 



darker ; sepals oval ; petals rhomboid, much broader ; lip with a broad 



claw and orbicular blade, downy on the upper surface.

t The colour of the spot on the lip of Dendrobium Infundibulum varies from cinnabar-red 

 to pale flesh ; it not only varies in different plants, but it has also been observed to vary 

 in the same plant in different seasons. Those plants whose flowers have the red spot are 

 often but erroneously called D. Jamesianum, but the typical Jamcsianum, now seldom seen, 

 may be recognised by the characters indicated above. *
