GYNANDRIA. 351 



insensible gradation from one to the other, of which 

 we have pointed out other instances in treating of 

 this subject ah'eady, occurs in Diiirls^ ^. 8, 9; while 

 in some Orchidece the leaves all partake more of 

 the habit of a calyx, and in others of a corolla. 

 Even the lip in Thelymitra, t. 29, assumes the 

 exact form, colour, and texture, of the rest of the 

 flower ; which proves that a dissimilarity between 

 any of these parts is not always to be expected in 

 the family under consideration. Vahl appears by 

 the preface to his Enumeratio Plant arum to have 

 removed the Scitaminece to Gynandria, because the 

 stamen of Canna adheres to the style. This, if 

 constant, could only concern that genus, for the 

 rest of the Order are in no sense gynandrous. 



Diandria, To this Order Ci/pripedium, EngL 

 Bot. t. \y must be referred, having a pair of very 

 distinct double-celled anthers. See Tr. of Linn. 

 Soc. V. 1. ^. 2, 3. Here we find Forstera, so well 

 illustrated by Professor Swartz in vSims and Konig's 

 Annals of Botany, v. \. 9>9\, t.6; of which genus 

 Phyllachne, t. 5 of the same volume, is justly there 

 reckoned a species. Of the same natural order with 

 Forstera is Stylidium ; but that having, I think, 

 four anthers, belongs to the fourth Order of the 

 present Class. Gunnera, placed by Linnaeus in 

 Gynandrla Diandria, is not yet sufficiently well 

 understood.
