7. Corticated, (corticata), when the external coat 
ishard, and the internal soft; or when the exter- 
nal is spongy, and the inner membranaceous, as in 
Magnolia, Uhicium anisatum. 
Woody, (Jignosa), when the coat is very hard, 
but still bursts in valves. 
The Capsule has different names according to the 
various ways in which it opens, e.g. bursting at the 
top, (apice dehiscens); bursting at the base, (basi de- 
biscens), bursting in the middle, (circumscissa), open- 
‘ing with a lid, operculata, &c. 
- The fruit of the Hepatic Mosses, (Musci hepatict), 
is likewise called a Capsule. They have over the 
Capsule a thin, light, deciduous membrane called 
calyptre, (calyptra). ‘The Capsule bursts in four or 
two valves, (guadri-vel bivalvis), fig. 227. The 
four or more valve-like bodies are called threads, 
(fila). At the seeds are other threads formed like 
a small chain, which are called catenule. In the 
bivalved. capsules there is a slender column on which 
the seeds hang, which is called columnula s. sporan- 
gidium, : | 
The Filices have one or more capsules, in general 
<idney-shaped, which form on some an elevated ar- 
ticulated border: _ This border is called finbria.

The nur, (mux), is a seed covered with a hard 
shell, which does not burst; as the hazle-nut, Cory- 
Jus avellana, the oak, Quercus robur, the hemp, Can- 
nabis sativa, fig. 205. ‘The shell is called Puramen, 
und 1s deseribed according as it is hard (durum), or 
brittle
