is Tribe contains those Monocotyledonous Vegetables, in which 
the floral Envelope, e often green and small, is never of a trul 
— or chaffy texture. In eal Genera, its three outer 
parts are calycine and not staminiferous, while its three inner parts 
are petaloid and staminiferous. In ot thers, the Stamina are inserted 
in the Receptacle, quite detached from the floral Envelope, and this 
even when the Pericarpium is inferum, Galanthus for instance. In 
more Stamina are inserted higher up in the floral Envelope, like

Clas. 1. SPADICIFERÆ. 
No two Classes of ' Dicotyledonous and diede Vegetables 
yet discovered, are in my judgment so nearly allied to one another, 
foetid eadaverous smell. In a rich Peers at Er ae, that of Arum 
Muscivorum measured tw abr evo inches in leng and Hvwsorpr 
records one of an Aristolochia large enough to make children’ s Hats. 
The similarity of Foliage in the two Classes moreover is striking, 
I do not yet know any exclusive definition of Spadicifere, and they 
trust be illustrated by Rrcuarp, who has examined and made 
n 
a vast many other Monocotyledones, but the structure of that part 
differs here even in Genera of the same Order, Richardia for instance, 
so nearly akin to Calla, has a Cotyledon somewhat com and 
quite a different. aperture wedge-shaped, forming a pgs exactly 
like that of Dioscorea, which I = as an approach to a second
