cm. longa. Flores 10-24, sessiles, virides, pediculus per- 

 brevis, Segmenta p€^rianthii glandulosa. Sepalum dorsale 

 erectum v. recurvum, ovato-lanceolatum, concavum, acumina- 

 tum, circiter 5*75 mm. longum; lateralia libera, patentia, 

 leviter apicibus recurva, circiter 7 mm. longa. Petala erecta, 

 anguste oblonga v. lineari-lanceolata, circiter 5 mm. longa. 

 Labellum sessile, basi subgibbosum, ad column am erectum ; 

 deind© recurvum sigmoideum, ad apicem contractum et 

 brevissime ciliatum, marginibus crenulatis ; pars callosa ovato- 

 lanceolata, marginibus anticis ciliatis, paulum ultra primum 

 flexum producta ; pars membranacea latiuscula, alba, inferiore 

 dimidio levis, in superiore dimidio rugosa. Columnae laciniae 

 late oblongae ; apicibus obtusis obliquis ; rostellum in 

 altidudine excedentes. Antliera rostello brevior. 



A slender green plant, 12-24 cm. high. Lamina of leaf 

 dilated at the base, thereafter setaceous or narrowly linear, 

 about same length as the spike. Flowers almost sessile in 

 a loose spike, their very short pedicel subtended by a broad 

 short blunt bract, entirely green, recurved from the axis of 

 inflorescence; ovary 4-5 mm. long, obovate; all segm.ents very 

 glandular. Dorsal sepal erect or recurved, concave, ovate- 

 lanceolate, acuminate, slightly contracted at the base. Lateral 

 sepals quite free, spreading but only slightly divergent, tips 

 slightly recurved, concave on upper surface, narrow lanceolate. 

 Lateral petals erect, narrowly oblong or linear-lanceolate, not 

 very acute. Labellum sessile; rather gibbous at the base, 

 but not protruding between the sepals; proximal part erect 

 against the column, the margins entire until a little beyond 

 the middle; thereafter recurved so as to form a complete 

 sigmoid flexure, laterally contracted towards the apex, the 

 margins crenulate and very shortly ciliate from the first 

 bend to the extreme tip ; the callous portion dark green, 

 ovate-lanceolate, extending from the base to a little beyond 

 the first flexure, its termination concealed by the lateral con- 

 traction of the lamina at that point, its margins shortly 

 ciliate; the membranous part rather wide, whitish, smooth 

 in the erect part, rather rugose anteriorly, very glandular, 

 more or less tomentose towards the tip. Lateral appendages 

 of the column relatively large, broadly oblong, with blunt 

 oblique tips, basal lobes distinct, exceeding the rostellum in 

 height. Anther shorter than the rostellum. 



Named after Mr. A. B. Braine, an ardent collector and 

 student of Victorian orchids.

The new species approaches the green forms of P. fuscitm, 

 but materially differs from it in the much less complicated 

 structure of the labellum and shorter lateral appendages of 

 the latter.
