" Tf Flowers (not on a spadix) in a dense, involucrate head." 



"[[Flowers (not on a spadix) solitary, racemed, spicate, &c." The latter is true 

 here. Refer to (3). 



" 3 Perianth tube adherent to the ovary, wholly or partly."

 pupil reads : 



" * 5 Flowers dioecious or polygamous. Low aquatic herbs." 



' * 5 Flowers dioecious, G-androus. Shrubby climbers." 



" * Flowers perfect" The last is true of our specimens. Refer to the dash ( ), 

 and read, " Gynandrous." 

 " Monandrous." 

 " 3-6-androus." It is 6-androus. Refer the next pupil to (6). 



" 6 Perianth woolly or mealy out-side."

" Stamens 6." The last is true of our plant. It must, therefore, 

 belong to the Nat Ord. AMARYLLIDACKE. Turn to that order, and 



932. DETERMINE THE GENUS, AND SPECIES. Further illustrations are unneces- 

 sary.
