92 ORCHIDACEM 



emarginate. Flowers solitary, 2.7 cm. across, opposite the leaves. 

 Pedicels slender, about 7 mm. long. Sepals and petals revolute, 

 acute, the lateral sepals broadest. Petals narrower than the upper 

 sepal, oblong-lanceolate. Labellum 3-lobed, about 2 cm. long ; 

 lateral lobes spathulate-obovate ; middle lobe obcordate, emargi- 

 nate, slightly apiculate ; disc with several raised nerves. Clinan- 

 drium 3-toothed, the posterior tooth subulate. Nearly related 

 to D. revolutiim, Lindl., but differing from it in the broad, 

 obcordate Hp and large spathulate lateral lobes. In The Flora 

 of British India, Sir Joseph Hooker has given D. imifiorum, 

 Griff., as a synonym of D. revolution, Lindl. The species is vari- 

 able, and the forms now recognized as distinct may be found to 

 make up one polymorphic species.

Stems slender, branching, about 6 dm. long, jointed, swollen at 

 the joints. Leaves oblong-lanceolate, 3-7 cm. long, 1-1.5 cm. 

 wide, acute, deciduous. Flowers produced on the leafless stems, 

 fasciculate, about 3 cm. long. Sepals oblong-lanceolate, acute. 

 Petals elliptic, about 2.5 cm. long, obtuse. Lip undivided, obo- 

 vate, apiculate. The apical half of the perianth organs and the 

 base of the lip stained and suffused with mauve. In The Gar- 

 dener's Chronicle, 1897, 2 : 121, fig. 34, this species is illustrated 

 with the flowers produced from a leafless stem ; in the Diction- 

 naire Iconographique des Orchidees they are figured as arising 

 from a leafy stem. The former agrees with the specimens I have
