i each, (Hooker’s Brit. Flora, p. 26.) Mr. Brown applies 
the term glume to the outer covering, or calyx of Hooker,

this case the proper involucre receives the epithet of general, 
or universal. See Fig. 19, par. 324. ; 
301. The spatha is a sheath completely enclosing the 
flowers before their expansion, and bursting longitudinally 
to make way for them, as in Snowdrop (Galanthus nivalis), 
Daffodil (Narcissus), Onion (Allium), and Wake Robin 
(Arum maculatum). In the latter example it encloses a 
spadix, and some restrict the term to this case. It is a sort 
of bractea or floral leaf, and Sir J. Smith gives it this name 
in the bulbous genera mentioned above. Many of the 
Palms have a spatha of a woody consistence. See Fig. 20, 
page 94, the Wake Robin. 
302. The cup (cupula) in the Cupulifere, in which the 
fruit rests, consists of a number of adhering bractem, as in 
the Oak, the Hazel. 
303. The glume or husk is something between a bractea 
Fig. 14. and a calyx, and is found in Graminee — 
and Cyperacex, which are destitute of 
proper calyx, This term is most gene- 
rally applied to the outer and thicker 
set of scaly leaves next to the sexual or-

seales (glume or calyx), and the inner 
seales (corolla), with the awn attached. 
The stamens and pistils are removed. 
The bristly spiral appendage, called 
Arista or Awn, is attached to the inner

inner coverings as ealyx and corolla; and the former applies 
the term glume or valve to the individual pieces or leaves 0 
_ and considers the thin inner covering as the true p
