DIFFERENT FORMS OF THE NECTARIUM. 
375 
In Garidella, the nectaries are five bilabiate ones. Trollius lias 
nine linear flat bent bodies, perforated at the base on the inside; 
Isopyrum has five equal tubulose short nectaries, with a trilobate 
mouth inserted into the receptacle within the petals. 
In Arum, the nectaries resemble the Aliments of stamens, only 
that they thicken at bottom ; they come out in two rows from the 
middle of the spadix ; in Peganum, the Aliments themselves are di¬ 
lated into nectaries at the base; in Fevilea, they consist of Ave com¬ 
pressed bent threads placed alternate with the stamens; in Trichilia, 
the nectary is cylindric and tubulose, formed out of the ten Aliments 
shorter than the petals with a Ave toothed mouth. By this time it 
will be observed, that many nectaries already mentioned have an in¬ 
timate connexion with the germ, it is a situation so common with 
this part of the Aower that some persons have suspected the sole or 
principal use of it is to supply and foster the germ. Accordingly 
there are several other genera in which it is thus placed ; in Mira- 
bilis, it is permanent, globose, and incloses the germ ; in Cissus, it 
is a ring sounding the germ; in Cynanchum it is cylindric with a 
five-toothed mouth ; in Apocynum, Asclepias, and Stapelia it is 
made up of Ave bodies, which in the second, and last entirely con¬ 
ceal the stamens and pistils, and in the last also forms a double star, 
all of them about the germ, in Gaultheria; it is made up of ten 
short awl shaped crest bodies surrounding the germ about the sta¬ 
mens. 
It must not be dissembled, that of whatever use these bodies may 
be to the germ when they adhere to it, or are near it, they are fre¬ 
quently found on other parts of the fructiAcation. Many instances 
of this have already occurred, and to these we may add, that they are 
found on the petals in Bromelia, growing to each of the three above 
the base; in Berberris in two roundish orange coloured bodies at the 
base of each ; in Hermannia each petal having a little membrane, alto¬ 
gether forming a cowled tube; Hydrophyllum, in Cumina or plates 
growing to them, and in Myosorus being Ave awl shaped bodies. 
The nectary is a globose gland on the exterior tip of the anthera; in 
Adenanthera, at the base of them; in Ainbrosinia, on the Aliments, 
in form of glands; in Dictamnus, in form of scales; in Zygophyl- 
lum placed horizontally on the Aliments; in Plumbago, and lastly, 
the nectaries are not unfrequently placed on the receptacle as in 
Clutia, and some others ; but these are so close to the germ, which 
takes its rise from the same base that they may very well be supposed 
to be placed there for its use. 
But what shall we say when we And the nectary in the incomplete 
staminiferous Aowers, which have no germ, as in Salix, where it cer¬ 
tainly cannot be of any immediate use to the germ, which is not only 
on a distinct Aower but on a different plant; -this however being the 
most important part of the vegetable, since it is destined by nature 
to produce a new one of the same kind, and all the other parts of the 
flower being subservient to this, in some measure, whatsoever is im¬ 
mediately useful to these may fairly be said to be immediately ser¬ 
viceable to the germ.
