This looks like a gigantic 7’. Arachnites, Reichb. f.; I found a 
plant somewhat like it on rocks of Kedah Peak, but the flowers 
were not open.

Evidently a common plant, but seldom collected as it is not 
often found in flower. Sarcochilus borneensis, Rolfe, in Illustr. 
Hortic., xxxix. (1892) p. 99, t. 161, looks like a finely-grown 
plant of this species.

This is near 7’. longicauda, Ridl., from Borneo, but has longer 
and narrower leaves, closely approximated as in Tl’. Arachiites, 
Reichb. f., of which the plant has much the habit. It differs 
from that species, however, in its much longer and narrower 
leaves, much larger flower, and different colouring. It is the 
prettiest species I have seen.
