Western Australia: Lake Chockerup, Mrs. A. Y. Ha^ell 

 and R. S. Rogers, November, 1919. 



The leaves of this rare plant were identified in situ at 

 Lake Chockerup. Some young plants were removed by Dr. 

 A. Syme Johnson and cultivated in Albany, where they 

 bloomed about the middle of November the same year. An 

 opportunity was thus afforded to examine the plant in a living 

 state and so supplement the original description of F. v. 

 Miieller ''from the few dried and much shrivelled specimens 

 hitherto secured." Plant, 18-23 cm. ; tuber oblong-ellipsoidal, 

 about I'S cm. long; membranous, acute, ovate sheath investing 

 the stem below the leaves. Leaves three, light green tending 

 to turn yellow as flower matures, sessile, at or near the base, 

 clasping the stem at their insertion; the lowest ovate- 

 lanceolate, reticulated, coriaceous, about 5 cm. long and 

 2*3 cm. broad, spreading, overlapping the base of the second 

 leaf; latter much smaller, lanceolate, more vertical than the 

 one below it, about 2 cm. long, overlapping the base of the 

 upper leaf; upper leaf very similar to the middle one; 

 sometimes an acute lanceolate bract near the middle of the 

 stem. Flowers 2-4 (in specimens examined) ; on rather long, 

 slender pedicels each subtended by a rather larg^e lanceolate 

 bract; a floral rudiment sometimes arising alongside the 

 uppermost pedicel ; white with pink shading and deep crimson 

 marl^ and dots. Segments of the perianth about equal, 

 + 16 mm, in length in the dried undissected flower (rather 

 longer when dissected and extended). Lateral sepals spread- 

 ing, ob-falcate, the bases very attenuated, 3-nerved, spotted; 

 dorsal sepal erect, much wider, very concave and cucullate, 

 contracted at the base. Lateral petals falcate-lanceolate, 

 contracted at the base, 3-nerved, spotted. Labellum almost 

 obovate with long attenuated base; erect in lower half, 

 gradually recurved forward above the middle; margins 

 crenulated but not fringed; about 12 mm. long (or 13'5 mm. 

 when extended) ; lamina traversed for its entire length with 

 numerous prominent longitudinal nerves, with scattered sessile
