entire and lanceolate or divided into two lobes. Anthers erect. Pollen- 

 masses granular, attached to long caudicles. — Terrestrial herbs, with a creeping 

 rhizome and weak ascending leafy stems. Flowers in terminal spilces, loose in 

 the Australian species, dense and one-sided in the typical northern ones. 



The genus is generally distributed over the tropical and temperate regions of the Old Worlds 

 Of the two Australian species one appears identical with an Asiatic one, the other, as far as. 

 known, is endemic.— i3m(ft.

 vi. 318. Stems ascending from 6in. to 1ft. Leaves on rather long petioles^ 

 dilated at the base into a loose searious sheath, the lamina ovate-lanceolate or 

 ovate-oblong, acute or shortly acuminate, sometimes slightly cordate at the base,. 

 1-J- to Sin. long ; and usually 2 or 3 empty searious bracts above the leaves.. 

 Flowers rather distant,, in a spike of 2 to 4in.,the bracts broad, membranous, 

 subulate-acuminate, often as long as the ovary. Dorsal sepal and petals B to. 

 4 lines long, the petals broader and more obtuse than the sepal, and usually 

 cohering to it ; lateral sepals obliquely lanceolate. Labellum as long as the 

 sepals, broadly ovate, very concave, rather copiously fringed inside with short, 

 cilia near the base. Eostellum divided into linear-lanceolate erect lobes as long 

 as the long acuminate anther, stigma pouch-like, almost truncate. — Keottia

2. G. polygonoides (Polygonum-like), F. v. M. Fraijm. viii. 29; Benth. FL 

 Austr. vi. 313. Stems from a creeping rhizome ascending, about Sin. long 

 including the raceme. Leaves petiolate above the loose searious sheath, oblong- 

 lanceolate, \\ to Sin. long. Spikes with peduncles 9in. high, pubescent, the 

 flowers small on a long ovary attenuate upwards. Bracts lanceolate, about as 

 long as the ovary. Sepals and petals about 1\ lines long, ovate or ovate- 

 lanceolate, the sepals acute, the petals thin and adnate to the dorsal sepal. 

 Labellum not very broad, acutely acuminate, rather longer than the sepals, very 

 concave, without hairs or appendages inside. Column short, the stigma, 

 membranous, large concave and undulate, but not pouch-like. Eostellum 

 lanceolate, undivided, with an almost gland-like appendage on each side at the 

 base on the margin of the membrane connecting the stigma and anther. Capsule 

 ovate, |-in. long.

29. HET^RIA, Blume. 

 (From its being near to Goodyera.) 

 (BampJddia, Lindl.) 

 Flowers reversed. Lateral sepals erect, broader at the base, forming a hood 

 over the labellum ; dorsal sepal and petals reflexed. Labellum erect, sessile, 

 undivided, concave. Column very short, with a narrow appendage on each side 

 connecting the base- of the anther and stigma into a cup. Anther erect. Pollen- 

 masses granular. Eostellum bifid, as long as the anther. — 'rerrestrial herbs, 

 with a creeping rhizome and ascending leafy stem. Flowers small, in a slender 

 terminal point. 



The genus is spread over East India and the Archipelago, the only Australian species having 

 nearly the range of the genus.
