a wide range in the western State. The flowers are white 

 with some purple markings; the inner plate of the labellum 

 being tomentose, an olive green in tint, and ending in two 

 raised knuckles just beyond the bend. In stature it is very 

 variable, and specimens were seen varying from 10 cm. (4 

 inches) to upwards of 60 cm. (2 feet). The lateral sepals are 

 very short (considerably less than the lateral petals), and 

 reach only to the bend in the labellum. 



P. cucullatum, Reich, f. 



Western Australia: Porongorup Mts. and Ravenswood, 



Rogers, September and October, 1919. Its distribution 

 appears to be rather localized, but it was found in considerable 

 numbers within restricted areas. 



This is a most dainty and attractive orchid. Sometimes 

 it is single-flowered, but often the flowers are very numerous 

 (40 or 50), constituting a dense blunt spike resembling that 

 of Orchis 'pyramidalis, Lin. The flowers are purple and 

 white and very strongly scented. 



The lateral sepals are the shortest segments of the 

 perianth (including labellum) ; they are connate to their 

 extreme tips, the conjoined lamina being widely dilated and 

 erect with incurved tip so as to form a hood in front of the 

 labellum. The dorsal sepal is dark purple, lanceolate and 

 reflexed. Tlie petals contracted and purple at the base, 

 otherwise white with purple "stripe down centre; rather 

 inflated towards the tips, spreading, and about the same 

 length as the dorsal sepal. The labellum is attached to a long 

 wateh-spring claw and is generally a little longer than the 

 lateral sepals ; it is erect for three-quarters of its length above 

 the claw, the tip being then bent forwards almost at right 

 angles; the erect portion at first narrow but gradually 

 increasing upwards towards the bend; the horizontal part 

 dilated into a semicircular tip with crenulated edges; the 

 lamina with two rather wide raised pubescent lines on the 

 erect part, the lines terminating just beyond the bend in the 

 centre of the horizontal part. The lateral appendages are 

 slightly shorter than the rostellum, oblong-falcate with their 

 falcate tips looking backwards. The anther is much shorter 

 than the rostellum; the caudicle very long.
