ORCHIDACEJ<: 



the bases of the upper leaves and at the apex of the stem, pellu- 

 cid in the dried specimen ; perianth segments connivent, con- 

 cave. Lateral sepals about 3.7 mm. long, 3.7 mm. wide, broadly 

 triangular-ovate, oblique, obtuse or acute, forming a deeply sac- 

 cate mentum, three- to five-nerved. Dorsal sepal about 3.3 mm. 

 long, 2.5 mm. broad across the middle, broadly ovate, acute or 

 obtuse, three-nerved. Petals about 3.2 mm. long, 1.8 mm. wide, 

 ovate, acute, three-nerved. I^ip connate with the column foot, in 

 natural position parallel to the column, sharply decurved near 

 the base, about 4-4.5 mm. long, about as broad across the lat- 

 eral lobes when spread out, spatulate-flabellate in outline, three- 

 lobed; claw broad, concave-involute, abruptly spreading into the 

 lamina; lateral lobes erect, oblong-rounded, porrect-spreading; 

 middle lobe reflexed, subequal to the lateral lobes, subc^uadrate, 

 broadly truncate shallowly retuse or bilobed ; a transverse, fleshy, 

 shallowly bilobed callus extends between the lateral lobes. 

 Column short, provided above with a fleshy wing which is 

 broadly truncate with a narrow apicule, extended below into a 

 broad saccate unciform foot. 



Collections from Mount Kinabalu show variations from the 

 type; for example, in Clemens 128 there occurs a much greater 

 sized flower with large middle lobe which lias divergent lobules. 

 Plants generally stouter and apparently much taller than the 

 type and with a similarly large middle lobe are shown by Clem- 

 ens 304. 



In vegetative characters Dcndrobium kiauense is very like 

 D. anceps Sw., but has a markedly distinct labellum. D. xipho- 

 phyllum Schltr., while a near ally, is distinguished by its petals 

 and far smaller lip with a four-lobed callus. D. lobatum (Bl.) IMiq. 

 is a more slender plant with differently proportioned flowers.
