 raceme 6-12 in., green ; bracts -J in. ; sepals and petals 1 in., green ; lip not saccate

 factorily in Herbarium specimens of the flower (carefully moistened and laid out) 

 between this and flabelliformis.

 ? TENASSERIM, Parish. DISTRIB. Marianne Islands, Timor. 



Lea/ 4-10 in. diam., cuspidate, margin waved; petiole 4-8 in. Flowering stem 

 stout, 6-12 in. ; raceme lax-fid. ; flowers pale green ; sepals -f in. long, linear-lan- 

 ceolate, acute ; petals rather narrower, obtuse ; lip shorter than the sepals, like that 

 of P. carinata, but white, and glabrous. Differs from carinata in the many-nerved 

 leaf; the flowers are not readily distinguishable in dried specimens. In a drawing 

 by Parish the lip is represented as saccate at the base, truncate at the apex, with 

 three green medial nerves meeting in the apex, and many red side nerves. In his 

 specimen the tip of the lip varies to rounded, the side lobes are rounded, not acute 

 as in carinata, and its nerves are not rectangular but ascending. 



DOUBTFUL SPECIES. 



POGONIA No. 1, Griff. Notul. iii. 376; stem 4 in. 1-fld., flower 1 in. long, 

 sepals linear-lanceolate acuminate pale purplish-brown, petals narrower, lip white 3- 

 lobed, side lobes rounded-oblong denticulate, midlobe obovate crisped pubescent white 

 spotted and veined with purple and with 2 green veins and a yellow-green crest from 

 the middle downwards, margins papillose. Fields at Suddyah, in Upper Assam, smell 

 of violets.
