S8 VANDA. 



south-east Mindanao; V. lamellata occm-s with Aerides Quinque-vulnera 

 near Manila ; V. ccerulea grows near Aerides Fieldmgii on the 

 Khasia Hills ; V. tricolor is mixed with Aerides virens in Java ; 

 and other instances are indicated on the map. 



Cidtural Note. — Tlie cultural routine for the majority of the Yandas 

 is the same as that for Aerides. Special cultural notes are given 

 under the description of those species that are exceptions to the general 

 rule. 



Synopsis of Species axd Yaeieties. 

 Vanda alpiaa. 



Stem hut a few inches high and not thicker than a goose's quill. 



Leaves hroadly linear, 2 — 3 inches long, unequally bi-lobed at the 



apex. Peduncles with one — two joints, at each of which is a 



scarious bract, one — two flowered. Flowers 1^ inch across, vertically; 



sepals and petals light yellow-green, the dorsal sepal spathulate-oblong, 



the lateral two ovate-oblong, the petals linear- oblong, all more or less 



incurved ; lip fleshy, saccate at the base, three-lobed, the side lobes 



triangular, erect, concave, and blackish purple on the inner side ; the 



front lobe cordate at the base, gently reflexed, and with two horn-like

 Griffithii, Lindl. in Paxt. Fl. Gard. sub. t. 41. Luisia alpina, Lindl. in Bot. Reg. 

 1838, misc. No. 101. 



Discovered by Gibson in 1836 at Nungklow on the Khasia Hills^ 



and introduced by him to Chatsworth in the following- year. It was 



subsequently detected by Sir J. D. Hooker and Dr. Thomson on 



the same hills at 3,500 — 5,000 feet elevation, where, in the winter 



months, hoar-frost is formed on the ground and snow has been 



known to fall. It is very near Vanda cristata, of which it may be 



only an alpine form, and to which it is inferior in beauty. We are 



indebted to Mr. R. Irwin Lynch, Curator of the Botanic Garden, 



Cambridge, for materials for description. 



V. Amesiana. 



Stems but a few inches high. Roots numerous and very thick in 

 proportion to the size of the plant. Leaves fleshy, semi-terete with a 

 grooved face, 7 — 12 inches long, narrowed from the base to the acute 

 tip. Peduncles ascending, longer than the leavtjs, dull green dotted 

 with deep purple, racemo.se, rarely paniculate along the distal half.
