À large genus of very variable plants, confined, so far as is at present known, to Australia and the New Zea- 
land Islands. The species may readily be recognized by their coated bulbs, which are not pedicelled, solitary fistu- 
lar leaves, and spike of small flowers, which have the labellum above. Mr. Archer has made a detailed study of the 
Tasmanian species, and 1 have gladly availed myself of his arrangement and characters of the species; these 
appear to me good, though I must own it is not possible to find in all the dried specimens of any species all the 
characters we agree in considering to be the diagnostics of that species : still the difficulties are not nearly so great in 
this genus as in Microtis and Thelymitra. The genus Genoplesium, founded by Brown upon a drawing of Bauer's, 
we have included in Prasophyllum, with an amended character, Bauer appearing to us to have confounded the 
petals with the staminodia, though we must confess that it is difficult to understand how he came to do so; as 
however the different views of these organs, as represented by Bauer, are not consistent with one another, we are 
unavoidably compelled to suspect some error.—(Name from rpacov, a leek, and $vAXov, a leaf.)
