PRINCIFIA 
3d. Stamineous nectaria, such as attend the stamina, 
and are either seated upon the anthers®, as in adcnunt.hcra; or 
hpon the filaments, as in laurus , dictamnus, campanula, Sic. 
4th. Pistillaceous nectaria, such as accompany the 
pistillum and are placed upon the gennen, as in hyacinthus, 
butomus, cheiranthus, hesperis, &c. 
5th. Receptaculaceous nectaria, such as join to the 
receptacle, as in polygonum, sedum , sempervivum , &c. 
6th. Nectaria that crown the corolla,that is,when placed 
in a series or row within the petals, though entirely unconnected 
with their substance, as in passiflora, lychnis, silenc, &c.; and 
in this situation it often resembles a cup, as in narcissus, Sic. 
7th. Nectaria of singular construction, being such as 
cannot properly be placed under any of the foregoing dis¬ 
tinctions, as in amomum, curcuma, salix, urtica, &e. 
III. The STAMINA, (threads or chives). These are the 
males of the flower, proceeding from the wood of the plant, 
each stamen consisting of two parts, (viz.) the filament and 
the anthera; and in most flowers are placed upon the recep¬ 
tacle, within the corolla, and round the germen ; and are 
chiefly distinguished by number. 
The Filament (from filum, a thread) is the thread-shaped 
part of the stamen, serving as a footstalk to elevate the 
antherae, and is sometimes found to have jags or divisions, 
(lacinise) which are either two, as in salvia; three, as in 
fumaria ; or nine, as in the class diadelphia* They are also 
distinguished by their form or figure, as awl-shaped, thread¬ 
shaped, hair-like, spiral, revolute. Sic. - also by their pro¬ 
portion, as equal, unequal, irregular, long, or short; also by 
their situation, being generally opposite to the leaves or 
divisions of the calyx, and alternate w r ith the petals ; that is, 
when the divisions of the calyx are equal in number to 
the petals, and to the stamina.* In flowers of one petal 
* By this rule it may generally be known whether calyx or corolla be wanting, 
when there is a deficiency in either. But in aletris the stamens are an exception
