 Vanda Vipanii, Rchb. in Gard. Chron. XVIII. (1882). p. 134. 

 Discovered in Burmah by Captain J. A. Vipan a short time 

 previous to the publication of the name. It is still a very rare and 

 little known species in cultivation. The above description was taken 

 from a plant that flowered in our houses in the summer of 1887.

SACCOLABIUM. 



Bliime, Bijdr. p. 292 (1825). Benth. et Hook. Gen. Plant. III. p. 538[(1883). 



Saccolabium includes upwards of forty species, most of which are 

 plants of dwarf habit bearing racemes of small flowers offering but 

 little attraction to the cultivator. By far the greatest number of the 

 Saccolabiums inhabit British India, where, in some localities, they are 

 among the commonest of orchids; a few other species known to 

 science are scattered over the Malay Archipelago. Sir J. D. Hooker 

 has distributed the Indian species, including several previously referred 

 to Lindley's Acampe, into seven series each distinguished by some 

 common character observable in the structure of the flower, or in the 

 vegetative organs.* 



Of the nine species described in the following pages, two, Saccolabium 

 giganteum and 8. violaceum, are aberrant ; the first was brought under 

 Saccolabium by Lindley but afterwards removed by him to Vanda ; 



* Fl. Brit. Ind. VI. p. 55. All the Malayan species known to us may be referred to one or 

 other of these series (sections).
