DIFFERENT FORMS OF THE NECTARIUM. 
ence. This is the case with several plants of the 1st class, and with 
Lecythis in class thirteen ; with all these it is of one petal, in Galan- 
thus it consists of three parallel, notched, obtuse, petal-like leaflets 
forming a cylinder, about half the length of the corolla. Illicium 
has several awl shaped folioles of the same length of the petals them¬ 
selves. Cardiospermum has a four petaled nectary inclosing the 
germ, Hartogia of five petals. Andrachne has five semi-bifid her¬ 
baceous folioles, less than the petals, and placed between them all the 
Grasses, Rice, and Mays, agree in having a nectary of two oblong 
minute leaflets. Melianthus has a one leaved nectary within the low¬ 
est division of the calyx to which it grows. In Musa, one boat 
shaped leaf compressed, pointed, and inserted within the bosom of 
the petal. Ten converging leaflets inclosing the germ form the nec¬ 
tary of Zygopliyllum, each leaflet being fixed to the base of each Ali¬ 
ment. Dalechampia has a broad nectary composed of many ovate 
flat plates in several rows. In many genera with tubular corollas, 
there is a horn or spur at the back of the flower which answers the 
purpose of a recipient, as in Delphinium, &c. In some species of 
Anthirrinum the horn is blunted, and becomes rather a bag which is 
also its shape in Satyrium. In Ophrys, it hangs down from the co¬ 
rolla longer than the petals, and is keeled in the back part; in Sera- 
pius, it is of the same length of the petals, of one leaf concave, stand¬ 
ing on a pedicle and within the lowest petal; in Arethusa, it is of 
one leaf, tubulose at the bottom of the ringent corolla, and connate 
with it, in Cypripedium, is very large and inflated, and in Epiden- 
drum, it is tubulose at the base, turbinate with an oblique bifid 
mouth. Thus it is observed that all the genera of this tube have sin¬ 
gular nectaries, whereas in the third classes (Ifi, 17, 18,) with con¬ 
joined filiments, scarcely any are to be found. The numerous genus 
Carex has an inflated permanent nectary, contracting above and 
toothed at top, where it gapes, but continues to invest the seed, in 
Ruscus also it is inflated, and open at top, it is ovate, erect, and of 
the same size of the calyx: 
In many genera, the nectary takes the form of some well known 
utensil, or other thing; thus in Staphylea it is urceolate or pitcher 
shaped; in Narcissus, it is infundibiliform, or funnel-shaped ; in 
Epimedium it is c.yathiform, or goblet shaped; in Ayenia, it is bell 
shaped, in Cissampelis, it is well shaped, and in Epidendrum it is 
turbinate or top shaped narrow at bottom, and spreading out above. 
The most beautiful of these is the crown shaped; in Diosma, this is 
placed on the germ; in Olax, it terminates the corolla, but in Passi- 
flora, it is a triple crown, the outer one longest surrounding the 
style.
