 with long spreading hairs mixed with shorter sometimes glandular ones as in

 always 1-flowered. Leaf lanceolate, the small sheathing bract usually green. 

 Flower blue. Sepals and petals oblong-lanceolate, 5 to 6 lines long. Labellum

 glabrous, the basal ealli or appendages 2, linear, flattetied, clavate at the end, 

 rather shorter than the column, very shortly united at the base. Column nearly 

 as long as the labellum, broadly winged but the wing not produced on the anther.

44. CALOCHILUS, E. Br. 



(From halos, beautiful ; cheilos, a lip.) 



Dorsal sepal erect, rather broad, concave ; lateral sepals about as long, broadly 

 lanceolate, spreading ; petals much shorter, broadly falcate. Labellum as long 

 or longer, undivided, contracted at the base, the margin and whole surface 

 densely fringed except a narrow terminal point or ligula. Column short, with a 

 rather broad wing more or less produced behind the anther but not beyond it. 

 Anther bent forward at the base, usually recurved towards the end, obtuse or 

 obtusely acuminate or rostrate. Pollen-masses granular. Rostellum much 

 shorter than the anther. — Terrestrial glabrous herbs, with ovoid underground 

 tubers. Leaf usually solitary, long and narrow, but usually 2 or 3 erect almost 

 leaf-like sheathing bracts on the stem. Flowers few in a terminal raceme, green 

 or yellow, with more or less of purple especially the labellum. 



The genus is limited to Australia. 



Anther rostrate. Column-wing quite open' in front, with a gland on each 



Bide -within its anterior angles or lobes 1. C campestrls. 



.Anther very obtuse. Column-wing without any gland, open in front. 

 Labellum with 2 short longitudinal intramarginal erect plates or auricles 

 near the base . . 2. C. paludosus.
