The original description of the species was based upon a 
specimen collected at Manila by Cuming, and according to Mr. 
Rolfe 3 the type plant flowered in the garden of Mr. Bateman 
in 1840. What is considered to be the same species was de¬ 
scribed as a Phalaenopsis ( P. fugax), but the structure of the 
flower is far from being that of a Phalaenopsis.

This is the third time that Sarcochilus unguiculatus has come 
to the attention of the junior author during a period of four 
years, and while in the beginning he suspected that the species 
was separable from the true S. pallidus (Bl.) Reichb. f., addi¬ 
tional data have convinced him of its distinctness. The flowers 
of S', pallidus last for a couple of hours only, opening early in 
the morning and generally wilting before noon, while records 
of the flowering of S. unguiculatus show that the flowers re¬ 
main in good condition longer, opening the first day and wilting 
on the third day. It flowers from May to July. 
Sarcochilus unguiculatus is distinct from S. pallidus, not only 
in the habit of the plant, but also in the following features. 
The leaves are disposed horizontally and are more rigid and 
tinged with purple on the lower surface. The racemes are 
decidedly shorter, the flowers are much smaller, the lateral
