15. THELYMITRA, Forst. 
Erect, stout or slender, scapigerous, glabrous herbs. Roots of ovoid tubers. 
Stem with a membranous sheath below the leaf. Leaves 1 or rarely 2, 
narrow, much elongated, thick and coriaceous. Flowers few, spiked or racemed. 
— Perianth spreading. Sepals and petals all oblong ovate or obovate, equal

3-tid ; lateral lobes (staminodia) erect or prominent, cremate or produced into 
feathery appendages; middle small, entire, notched or 3-fid. Anther posticous,

A large Australian aud Tasmanian genus, also found in New Zealand and the lofty moun- 
tains of Java. The species are most difficult of discrimination in a fresh state and impos- 
sible in a dried one ; aud the following all require revision. The only good characters I 
have been able to find are in the length and direction of the lateral lobes of the column. 
Flowers llue or purple. 
Column much longer than its short plumose appendages 1. T. longifolia. 
Column longer than its erect toothed appendages 2. T. pulchella. 
Column as long as its erect 2-toothed appendages 3. T. unifiora. 
Flowers yellowish, few, 1-3. Stems slender. 
Column much shorter than its erect plumose appendages 4. T. Colensoi. 
Column as long as its crenate or fimbriate appendages 5. T. imberbis.
