The flowers of this are very short-lived; they open rather late in the morning, and 
by evening they have withered. They appear singly at intervals of two or three 
weeks, and the raceme continues growing for several years. In colour the sepals and 
petals are yellow and the lip is speckled with red. In the Malayan countries the 
rachis often attains a length of many inches. As the bracts persist, the flowering rachis 
has a pectinate appearance. ; |

Siem pendulous, slender, woody, sheathed, 3 to 6 in. long. Leaves decurved, narrowly 
oblong, obliquely bifid at the apex, slightly narrowed at the base into а short stem- 
clasping sheath; length 3:5 to 7 in., breadth ‘65 to -85 in. Racemes pendulous, opposed 
to and usually longer than the leaves, many-flowered, their peduncles short and with a 
few short broad bracts. Flowers lax, “5 in. in diam.; floral bract minute, lanceolate, the 
stalked ovary very slender. Sepals sub-equal, narrowly obovate, blunt, the lateral pair 
slightly falcate. Petals smaller than the sepals, oblong, sub-acute, slightly faleate. Lip 
jointed to the foot of the column, narrowly infundibuliform, contracted below the slightly 
bulbous tip, slightly constricted also at the mouth; the side lobes small, oblong, their blunt 
apices pointing backwards; apical lobe very short, truncate. Column very stout, slightly 
dilated towards the apex, its foot strongly introflexed, as long as and running almost 
parallel to itself; rostellum short. Anther depressed, 2-celled; pollinia broadly ovoid, their 
‘apices divergent, attached by a thick short caudicle to the small gland. Sarcochilus
