2. P. pJjAVUM, R. Br. A plant of similar general appearance to the last, only 

 generally more robust. Leaf with a long sheath, and a lamina seldom more than 

 an inch long. Flowers numerous, pale, upper segments united except at the tips, 

 about 4 lines long. Labellum somewhat inflated in the lower half, the upper 

 half curved back, but not bent at an angle, as in P. anstrah ; the upper half 

 narrow, with a slightly wavy margin ; central plate prominent, and extending 

 throughout f of the labellum. Lateral lobes of the column shorter than the

3. P. ELATUM, R. Br. A tall robust plant, of similar habit and general 

 appearance as P. australe, but often 3 feet or more high. Leaf with a long 

 sheath and often a fairly long lamina. Flowers very numerous, rather large, 

 pale greenish-yellow. Outer segments about | inch long, the upper pair more 

 or less united, often free towards their base, the tips usually free. Labellum 

 but slightly curved, principally near the end, margin slightly wavy, central 

 plate very prominent and covering the greater portion of the labellum. Lateral 

 lobes of the column much exceeding the anther, linear, falcate, with a prominent 

 gland towards the base of the anteripr margin. P. australe, Hook.

 P. hrevilahre, verj narrow at the insertion, broad and wavy above ; central plate 

 narrow, not very prominent, not generally extending more than half way, but 

 variable. Lateral lobe of column about as long as the anther, broadly linear, 

 obtuse or obscurely 2-dentate, curved but not falcate, the gland on the anterior 

 margin prominent in some specimens, in others hardly apparent, even in fresh
