b Plumula, the ascending scaly part of the corculum. 
c Rostellum, the descending plain part of the corculum. 
d Arillus, the proper exterior coat or tunic of the seed. 
e Hilum, the eye, the external scar of the seed, where it has been 
fixed to the fruit or receptacle. 
f Cotyledon, the side lobes of a seed, of a porous substance. 
g Corona, a crown, a little cup adhering to the top of the seed by 
which it flies. It is either 
Pappus, a downy feathery cup, assisting the seed to fly. 
Stipulatus, a kind of thread like trunk, elevating the down. 
Capillaris, undivided hairs. Plumoses, feathery hairs. 
Ala, a membranaceous wing, fixed to the seed. 
2. Nux, a nut, a seed covered with a bony epidermis, called the 
shell, having one, two, or more cells. 
3. Propago, the seed of a moss, having neither tunic, nor cotyle¬ 
don, but consists only of. the plumula of a naked corculum, where 
the rostellum is inserted into the calyx of the plant. 
7 and last part of the fructification, Receptaculum, a receptacle, is 
the base which connects the six parts together. It is either 
1. Propium, proper, is that which belongs only to a single fructi¬

a Fructificationis, common to both flower and fruit. 
b Floris, containing the flower, but not the fruit. 
c Fructus, containing the fruit, without the flower. 
d Seminis, a base that fastens the seed within the fruit. 
2. Commune, common, containing many florets and fruit. 
a C. Paleaceum, chaffy scales, which distinguished the florets. 
3. Umbella, an umbel, a receptacle which from a common centre, 
runs out into thread-shaped footstalks of proportionate lengths. 
a U. simplex, when the footstalks proceed from one and the same 
centre of the receptacle. 
b U. composita, when every footstalk of the general umbel pro¬ 
duces a partial one. 
c U. partialis, a partial umbel, a part supported by the universal 
one. 
d U. universalis, composed of many simple umbels. 
e U. prolifera, an umbel, more than decompound. 
4. Cyma, a receptacle, producing many footstalks from the same
