of flowers 9 inches long. ’

Possibly this may be the same as P. flavum. It is a tall plant with the 
habit of P. elatum.

Very near P. macrotys from which it chiefly differs in the form of the lip, 
and in the shorter column-lobes. The species from P. australe to the 
present are tall stout plants, difficult to distinguish and perhaps not speci- 
fically different.

Hab. in Tasmannia; R. Brown; inter rupes, rarum, Gunn, 929. (hab. 
8. Sp.) 
Mr. Gunn informs me that this plant possesses a delightful fragrance 
like the Hyacinth ; some others, as P. patens, have a slight smell, but 
others are inodorous. It appears to vary a good deal in size, and in the 
length of the spike, the flowers of which are however always distinct, aud 
not at all imbricated. I find the lip occasionally a little downy at the 
back.
