78 Mr. MiERs's Description of a 



the flower expands. In the male plant are observed three distant pairs of 

 anther-lobes, of an oval form, suspended side by side from the summit of 

 corresponding cavities in the base of a somewhat three-sided, central, hyaline 

 cone of a fleshy consistence, which, when cut through, exhibits a structure 

 formed of numerous minute, lengthened, adhering cells ; the lobes of the an- 

 thers are opake and white, bursting outwardly by a longitudinal fissure: the 

 pollen is white and somewhat farinaceous. These pairs of anther-lobes pro- 

 bably belong to different stamina, the enlarged connectives of which form the 

 bulk of the fleshy cone ; in which view of the case the stamina would be placed 

 opposite to the segments of the perianthium, and not alternate with them, as 

 they at first sight appear. In the female plant, which in size and habit exactly 

 resembles the other sex, the structure of the perianthium is precisely similar; 

 and in lieu of the central staminiferous cone, there appears an entirely superior, 

 semiglobular mass, consisting of innumerable minute carpels, with rather long, 

 subulate, free-pointed styles : though I could not distinguish any stigma, it is 

 probable that this organ, which is too minute to be seen, is lateral, since the 

 summit of the style is somewhat gibbous. I cannot find a record of any plant 

 bearing a resemblance to the one under consideration, which I believe to be 

 quite new, and may, from the very characteristic subulate processes of the 

 perianthium, be better distinguished by the name of Triuris than by that of 

 Mycopsis, by which I had at first designated it. The following are the details 



of its characters : —
