ORCHIDACE^ 



2. Malleola transversisaccata A.8^S. sp. nov. Herba cras- 

 sior, arcLiata. Radices numerosae, fibrosae, rigidae. Caulis vaginis 

 coriaceis foliorum omnino obtectus. Folia disticha, late patentia, 

 elliptico-oblonga vel linearia, apice oblique bilobata, ad basim 

 complicatam angustata, coriacea. Pedunculi circiter tres, oppo- 

 sitifolii, simplices. Rachis densissime multiflora. Bracteae inflo- 

 rescentiae triangulares, acuminatae,reflexae. Flores parvi, in sicco 

 pellucidi. Sepala lateralia late ovata, obliqua, obtusa. Sepalum 

 dorsale ovatum, cucullatum, apice rotundatum. Petala ovata, 

 acuta. Labellum conspicue calcaratum ; lobi laterales inconspicui, 

 retrorsum extensi ; lobus medius conspicuus, adscendens, angus- 

 tissime triangularis ; calcar cylindraceum, ad apicem in saccum 

 transverse ovoideum dilatatum. Gynostemium parvum, malleo- 

 liforme. Anthera pileata. Pollinia duo ad summam stipitis cune- 

 ato-dilatati. 



Plant rather stout, arcuate. Roots numerous below, fibrous, 

 rigid, flexuous, conspicuously sulcate, sparsely branched, 1-2 mm. 

 thick. Stem merging into a root-like portion below, about 15- 

 26 cm. long (but broken off at the base; a dwarf plant has stem 

 6.2 cm. long), entirely concealed by the leaf sheaths, zigzag. Leaf 

 sheaths — the lower becoming fibrous, the upper loose — infundi- 

 buliform, laterally flattened, coriaceous, striate-nervose. Leaves 

 eight to ten, distichous, widely spreading, about 8.5-10.6 cm. 

 long, 1.25-2.35 cm. wide, at intervals of ±1.5 cm., lance-oblong, 

 elliptic-oblong or linear, rounded at the apex and very obliquely 

 bilobed with vertically semi-orbicular lobules which are minutely 

 erose, obliquely narrowed to a complicate sessile base, coriaceous, 

 many-nerved with the mid-nerve more or less sulcate above and 

 prominently carinate beneath. Peduncles about three, slightly 

 shorter than or little surpassing the leaves, puncturing the middle 

 or upper sheaths opposite the leaf-bases, spreading-arcuate or de-
