and supports both the stamina and pistillum. The 

 orders are nine, viz. 



ORDER I. DIANDRIA*, comprehending such 

 plants as have two stamina. The flowers of this or- 

 der have a most singular structure, answering to the 

 following description. 



Characters of the Order DIANDRIA, of the Class 

 GYNANDRIA. 



The gerrnen is always contort (like a screw.) The 

 petals are five; of which the two inner ones .usually 

 approach; and form a galea or helmet ; the lower 

 lip of which becomes anectariurn, and serves also for 

 a pistillum and sixth petal. The style grows to the 

 inner margin of the nectarium in such a manner, as 

 to be with its stigma scarce either of them distinguish-* 

 able. The Filaments are always two, supporting as 

 many antherae ; which are narrower downwards ; 

 naked, or without tunic, and divisible, like the pulp 

 of a Citrus. These last are covered by. little cells, 

 that are open underneath, and grow to the inner 

 margin itself of the nectarium. The fruit is- a cap- 

 sule, that is unilocular, trivalved, and splits in the 

 angles under the carinale, keel-shaped ribs. The 

 seeds are scobiform (like saw-dust) numerous, affixed 

 to a linear receptacle in each valve. 



ORDER I. DIANDRIA, comprehending such plants 

 as have two stamina. This order contains eleven 

 genera, viz. Orchis, Satyrium, Ophrys, Serapias, 

 Limodorum, Cypripedium, Epidendrum, Arethusa, 

 Gunnera, Disa and Forstera. 



ORDER II. TRIANDRTA, comprehending such 

 plants as have three stamina. This order contains 

 four genera, viz. Sisyrinchium, Ferraria, Salacia and 

 Stiiago. 



* This order is a natural one, the genera differing only in 

 respect to the nectarium. This part Linnaeus considers as a 

 mark of distinction for these genera, far preferable to the root, 

 though not received as such by former botanists.
