st:\*^vs, but also to emphasize the rathev close teiulency of some forms to bridge 
the gap between CyphoJophus ami Bochmcria on one hand and P)piurn!< and 
Potizol-ia on the other, with respect to this very character.^ 
Since its segregation by Woddell. no one has proposed to reduce riplurufi to 
any otlier genus, and certainly I liave no sncli intention. Nor, so far as I can 
ascertain, iias any recent writer wrongly referred to it any spctdes belonging 
elsewhere, although this discussion has arisen through my own reference tu 
Pouzolzia of a species which I now believe to !)e a Pipturu.'i. lint upon what 
character are these genera to he held distinct? Apparently, none can l>e drawn 
from the pistillate perianth, and even without going outside of Pouzohkt, there 
are species where that has been alleged to be adnate to the ovary, even as is 
the ease with Piptiirm, while I have failed fo find it so in either genus.- There 
remains the fleshy receptacle, so obvious to every observer in the field, so im- 
perfectly shown in the herbarium, although the early sUges even there have 
evidently been sudiciently indicative. This T believe to bo the correct solution. 
"Thero has been time to compare not*s with Mr. J. J. Smith, who has been 
able to make a further examination of Piptnrns rei^r^dm. He finds that its 
fruitin.^ perianth as well as its flowering one is thick and very succulent and 
replete with a viscid sap. The fruiting perianth is hardly longer than O.e 
flowering one, but the color, at first grass-green, changes into a dirty green His 
results have led to yet another e.vamination of P. arhore^cem, with full confirma- 
tion of the above statements regardi.ig it. The utmost concession that can be 
made is that the i)erianth is kept moist by the very succulent receptacle. 
The net result of the two series of observations would seem to 1;^ t^'"^J;^'^ 
nature of the perianth is not the same in all species of the genus, mt that they 
agree in the nature of the receptacle. Staminate receptacles are less perfeeth 
developed tVinii the pistillate.
