ney, a nearly universal fluid in Flowers, but not 

 always lodged in any organ, distinct or separate from 

 the Petals (55). When it is so, the Nectary is 

 either an assemblage of Glands f47 : 6), or a tubular 

 elongation of the Petal, or of the Calyx, or a sort 

 of Crown, or variously-formed appendage, to the 

 former. Honey brings insects about flowers, to as- 

 sist in the dispersion of the Pollen (58). 



58. Stamina, the Stamens, internal with respect to 

 the Corolla (54), are essential to every species of 

 plant, in some form or other. Each Stamen con- 

 sists of an Anthem, Anther, usually membranous, 

 of two cells, bursting lengthwise, or sometimes open- 

 ing by terminal pores, rarely by a lid or valve : and 

 of a Filamcntum, Filament, various in length and 

 proportion, supporting the Anther, but not invaii- 

 ably present. The Pollen, or Dust, contained in 

 the Anther, consists mostly of fine grains, bursting 

 with moisture, and discharging an elastic vapour. 

 In some of the Orchis tribe, the Asdepiadece (48 : 7), 

 fig. 185, Mirabilis, 167, and a few others, the Pollen 

 is glutinous, waxy, or elastic and very tenacious. 



59. Pistilla, the Pistils, central, essential, not always 

 in the same Flow r er with the Stamens, but in another 

 of the same species. Each consists of a Germcn * 



* Gaertner, who is followed by the French and some others, prefers 

 the term Ovarium to Germen. But Ovarium is used by anatomists for 

 a peculiar animal organ, unknown in vegetables, and can only lead to 

 error if applied to them. This has been shown long ago.
