1588 CXXVII. OECHIDE^. [Poyonia. 



Flowers 2 or 3 ia the raceme, nearly lin. long. Labellum quite entire, .» 



broadly obovate, the disk smooth 3. P. Ballacliyana. 



Flowers few, 3 to 4 lines long. Labellum entire, obcordate, glands in 



few rows ... 4. P. 



1. P. uniflora (single flowered), F. v. M. l<ragm. v. 201 ; Benth. Fl. Austr. 

 vi. 310. Flowering stem very slender, under Bin. long, with few rather long 

 loose sheathing scales and terminating in a single flower, blue' according to" 

 Dallachy, pink according to F. v. Mueller. Pedicel very short, the junction with 

 the stem marked by a small bract, wanting on some specimens. Sepals and 

 petals 6 to 7 lines long, linear, rather acute, the lateral sepals somewhat broader 

 or linear-lanceolate. Labellum nearly as long as the sepals, 8-lobed, the lateral 

 lobes broadly triangular and obtuse, the middle lobe at least as long, ovate- 

 oblong, obtuse, much contracted at the base ; disk with a papillose lipe, narrow 

 and double at the base, expanded upwards and extending partially on to the 

 middle lobe. Column very slender at the base, broadly 2-winged upwards. 



Hab.: Eockingham Bay, Dallachy. 



2. P. holochila (lip prominent), F. v. M. Fragm, vi. 200 ; Benth. Fl. Amtr, 

 vi. 810. Flowering stems slender, G to lOin. high, with a few rather long 

 sheathing scarious bracts, the upper ones sometimes almost leafy at the end. 

 Flowers 2 to 6, on slender pedicels of 1 to 8 lines, apparently pink, but lil^e those 

 P. uniflora said by Dallachy to be blue. Bracts linear, rather long. Sepals and 

 petals 7 to 8 lines long, the lateral sepals oblong-linear, the dorsal sepal and 

 petals narrow-linear, the petals more contracted at the base. Labellum nearly as 

 long as the S3pals, broadly ovate, shortly sinuate-3-lobed, the lateral lobes broadly 

 rounded, the middle one smaller, rather broader than long ; disk with a bearded 

 line extending to halfway along the middle lobe. Column slender, very shortly 

 winged at the apex.

 Vi. 810. Stems -about Gin. higb, with 2 or 8 long loose sheathing scales. 

 Flowers 2 or 8, on short pedicels crowded at the end of the stem. Bracts linear. 

 Sepals said to be reddish, nearly lin. long, narrow-lanceolate, acuminate, the 

 petals rather shorter and narrower. Labellum about fin. long, broadly obovate, 

 quite entire, contracted and embracing the column at its base ; the disk without 

 any raised papillose or bearded lines. Column 3 to 4 lines long, dilated and
