Epiblema. 

 E. grandiflorum, Br. 



Western Australia: Albany District, A. G. Hamilton, 

 1902; Chudalup Plains, E. H. Sutton, December, 1912; 

 Balbarrup, E. H. Sutton, March, 1912; Granite Bar (S.W.

Tliis remarkable species bears a strong superficial 

 resemblance to a Thelymitra, especially T. ixioides, Sw. Tlie 

 leaf is basal, narrow-linear. The flowers are blue. The 

 segments of the perianth are veined and much alike in shape 

 (elliptical or elliptical-lanceolate). The lateral petals are, 

 however, dotted along the lines of the longitudinal nerves. 

 The labellum is somewhat similar in shape to the other 

 segments and like them is traversed by parallel veins or nerves, 

 but in addition it is clawed and the lamina has a few worm- 

 like appendages at the extreme base. 



It is a late bloomer and apparently flowers well into the 

 hot weather. 



Calochilus. 

 C. Rohertsoni, Benth. 



This species appears in Mueller's Second Census with a 

 Western Australian habitat, but the writer has never received 

 it from that State.

The habit of this plant is suggestive of 

 D. pedunculata, Br., but the colouring is very different. The 

 upper-surface of the flower is a golden yellow, with a wall- 

 flower colouration at the base of the labellum around the 

 ''raised lines." The lower-surface is beautifully marked with 

 wall-flower veinings, parallel or divergent stripes on a yellow 

 ground. Flowers 2-4 in a raceme. Lateral sepals stout, 

 linear-lanceolate, very little longer than the labellum, 

 sometimes hardly as long ; dorsal sepal hiardly more than half 

 as long as the other segments, ovate-triangular. Lateral 

 petals golden-yellow above, wall-flower below, orbicular or 

 elliptical, on a claw about two-thirds the length of the 

 labellum, almost as long as the lateral sepals. The middle 

 lobe of the labellum is very wide and more than twice as 

 long as the lateral lobes, which are fringed or toothed along 

 the border and separated from the middle lobe a little above 

 the base. The two raised lines are situated widely apart on 

 the base of the lamina. There is a good deal of variation in
