84 ORCHIDE^, HYDROCHAR1DES. [CI. 4. 



long, with 3 principal ribs, or angles, each opposite 

 to a Calyx-leaf; Style, fig. 78, b, united, more or 

 less, with the Stamen, sometimes very short ; Stigma, 

 fig. 78, c, c, oblique, facing the Lip, concave, moist, 

 accompanied at the summit or sides with one or two 

 glands, fig. 72, g, either naked or in a membranous 

 pouch or pouches, serving to attach the discharged 

 Pollen. Capsule shaped like the Germen, of three 

 valves, splitting for the most part at their sides only, 

 between the ribs. Seeds very numerous and minute, 

 mostly tunicated with a loose membrane ; which is 

 wanting in Vanilla, where they are imbedded in pulp. 

 "Albumen the shape of the Seed." Gcertn. Embryo 

 minute, simple, central, near the Scar. — " The Flow- 

 ers of the Orchidece have their lower part, or Lip, 

 naturally placed inwards, but by a twist in their 

 Stalk, or base of the Germen, they are mostly turned 

 half round." Brown. 



They all, as far as hitherto known, belong properly 

 to Gynandr'ia Monandria of Linnaeus, Cypripedium 

 only being referable to Gynandr'ia Diandria. They 

 are well distributed into sections, by the three different 

 forms of the Anther, as above described ; the texture 

 of the Pollen being used by Mr. Brown for further 

 distinctions. The Genera are distinguished accord- 

 ing to these improved principles, in Comp. Fl. Brit. 

 ed. 2, 3 and 4, Engl. Fl. v. 4, and by Brown in Ait. 

 H. Kew. ed. 2, where they are greatly increased in 

 number.
