240. CONAMOMUM SERICEUM, n. Sp. 



Rhizome large, supported on stilt-roots. Leafy stems 8 

 feet tall. Leaves oblong-lanceolate, 18 inches long, 7 inches 

 across, narrowed at the base, shortly cuspidate at the apex, 

 glabrous except on the edges of the tip, dark green above, paler 

 beneath ; petiole short, grooved ; ligule \ inch long, oblong, 

 truncate, silky. Peduncles stout, 6-7 inches long, covered 

 with 5 large, glabrous, ribbed, truncate sheaths, about 2 inches 

 long. Spike cylindric, stout, 4 inches long, dense-flowered. 

 Rachis hairy ; pedicels half an inch long. Bracts urceolar, 

 subulate, with an acuminate cusp, pale, papery, silky, containing 

 2 flowers on short pedicels, the second enclosed in another and 

 smaller bract. Outer bract i inch long. Calyx tubular, thin, 

 papery, prolonged at one side into a cusp, glabrescent, half an 

 inch long. Corolla-tube short, hardly as long as the calyx; 

 lobes elliptic, oblong, white, shorter that the stamen, obtuse. 

 Lip 3-lobed, ovate ; lobes not deeply cut and subequal in length, 

 yellow, darker on the mid-lobe, base and side-lobes spotted 

 with pink. Anther oblong, crest 3-lobed, central lobe oblong, 

 truncate or rounded, side-lobes oblong, truncate or curved, 

 slightly acuminate, white tinted and spotted with pink. Fruit 

 not ripe, elliptic, ribbed when dry, glabrous. 



Gunong Tahan, in damp woods in the Gully and in the 

 woods bordering the streams in the Padang. Common. 



This species is allied to C. citrininn, Ridl., of the Taiping 

 Hills, and Bujong Malacca, differing in the papery, cuspidate, 

 pubescent bracts, the form of the lip (which is much more 

 distinctly lobed), silky ligule, etc. 



*24i. Geostachys elegans, Ridl. op. cit. p. 331. Com- 

 mon in the drier part of the woods on the upper slopes above 

 the streams. Also collected by Robinson. In many plants 

 the leaves are of a brilliant purple beneath, very attractive. 

 The corolla is yellow, the lip darker in colour, and there is a 

 pair of short linear crimson staminodes at the base. There are 

 two flowers in each bract, which I find also in some, at least, 

 of the type-form from Mt. Ophir. 



The only other localitv for this plant at present known is 

 Mt. Ophir. 



AMARYLLIDE^.. 



242. CURCULIGO LATIFOLIA, Dryaiid. ; antea, p. 59. 

 Narrowed-leaved form. Wet woods of the Teku, 4,600 feet 

 elevation. 



Distribution. Burmah, Andamans, whole Peninsula, and 

 Malay islands ; common, but seldom at any great altitude. 



BURMANNIACE^. 

 *243. BuRMANNiA LONGIFOLIA, Becc. ; Ridl. op. cit. p. 331 ; 

 antea, p. 59. Abundant in damp shady spots all over the 

 Padang, and along the ridges from about 4,000 feet upwards. 

 The flowers are white with blue corolla and calyx-lobes. 



Distribution. From Borneo (Sarawak) all over the Malay 

 Peninsula at an altitude of 3,000 to 6,000 feet. Absent from 

 M^ Ophir.
