 42. (,'. hicaUlata (sp. nov.) — A single specimen of this 

 dainty little orchid was found by Mrs. R. S. 

 Rogers near Kingscot-e on September 20, 1908. It 

 was growing in rather sandy soil near the road- 

 side on the margin of the scrub. Description. — 

 Plant not quite 4 in. high. Leaf linear-lanceo- 

 late, 2-|- in., hairy. Stem slender, hairy, a small 

 lanceolate bract about the middle and an ovate- 

 lanceolate subtending the flower. Flower soli- 

 tary, cream-coloured, with red veinings. Seg- 

 ments of the perianth are very similar to each 

 other, being expanded in the proximal part and 

 then suddenly contracted into rather coarse, 

 cylindrical hair}? caiidte ; each has a dark-red 

 line running down the middle on outer side. 

 The sepals are of equal length (9 lines), and the 

 lateral petals slightly shorter. In the case of 

 the dorsal sepal one-third is dilated ; in the case 

 of the other segments, one-half. The dorsal sepal 

 is slightly incurved over the column, the lateral 

 sepals spreading, the lateral petals divergent. 

 Labellum 3^- lines, marked divergent red veins, 

 recurved, clawed, point rather blunt, margins 

 (except of the erect part) serrated ; calli golf- 

 stick-shaped, in two well-defined rows, extend- 

 ing to within about a line of the tip. Column 

 incurved, widely winged in upper third, narrowly 

 below. Anther point absent in my specimen ; 

 basal glands also appear to be absent. Stigmatic 

 surface just below the anther.
