ORCHIDACE^ 



raceme, below sheathed by the petiole, which in turn is envel- 

 oped by a lanceolate membranaceous sheath, above suberect or 

 somewhat arcuate, slightly pubescent, provided with tubular 

 lanceolate appressed sheaths which are remote. Raceme 7-10 cm. 

 long, becoming loose with age. Rachis finely pubescent. Floral 

 bracts up to 1.9 cm. long, 6 mm. wide, reflexed-spreading, lance- 

 olate, acuminate. Flowers medium-sized for the genus, becoming 

 long pedicelled and reflexed in course of development. Sepals 

 pubescent without, margins more or less involute. Lateral sepals 

 about 1.05 cm. long, 4.5 mm. wide, oblong oblanceolate, some- 

 what oblique, acuminate, upper portion somewhat thickened. 

 Dorsal sepal about 1.15 cm. long, 4.4 mm. wide above, oblan- 

 ceolate to very narrowly elliptic, obtuse or subacute, concave. 

 Petals about 1 cm. long, 3 mm. wide above, narrowly oblanceo- 

 late, subacute. Lip adnate to the apex of the column, deeply 

 three-lobed, about 7 mm. long and 1 cm. wide across the horizon- 

 tally spreading lateral lobes, pluri-tuberculate at the base; lateral 

 lobes about 5 mm. long, 2.5 mm. wide, oblong, broadly rounded 

 at the oblique apex, which is sometimes apiculate; middle lobe 

 about 5-5.5 mm. long and nearly or quite as broad near the apex, 

 cuneate, retuse, anterior portion irregularly papillose-thickened, 

 erose especially on the lateral margins, sparsely pubescent be- 

 neath ; spur small, about 4.8 mm. long, stout, straight, pubescent 

 without. Column about 3.5 mm. long, stout, clavate, densely 

 pubescent or villous on the upper part. 



This plant differs from Calanthe kinabaluensis Rolfe in having 

 a far longer scape, shorter raceme and different middle lobe of 

 the lip. It is distinguished from C. abbreviata Lindl. by the rela- 

 tively small flowers and very hairy column.
