not yet named, has a Calyx in 10 divisions, 10 Petals, 

 and an indefinite number of perigynous Stamens ! 

 Another, Diplolana, found originally by Dampier, 

 and figured in his Voyage, v. 3. 110. t. 3. f. 3, bears 

 a double Involucrum, containing many decandrous 

 flowers, with Stamens and Pistils proper to the Order, 

 but only a few irregularly-placed scales in the place 

 of Perianth and Petals ! 



Jussieu's first Section undoubtedly constitutes a di-

 Metianthus, to whatever it may belong, (surely not, 

 as Jussieu hints, to Tropceolum^) has little affinity to 

 Diosfnece, or Zygophyllecs. 



Whether O.valis may be admitted into the former, 

 as being", in theoccasionallvlobed Filaments, elastic 

 Arillus, acid flavour, and number of parts, allied to 

 Boronia and Eriostemo?i, I merely beg leave to sug- 

 gest, till it can be more decisively placed elsewhere. 

 What has commonly been taken for an elastic Aril- 

 lus in the Diosmece or true Rutacea may, as in Eu- 

 phorbia, be only the inner coat of the Capsule, ac- 

 cording to the opinion of Jussieu and Richard. 



Ord. 82. CARYOPHYLLEiE. " Calyx of 1 leaf, 

 mostly permanent, either tubular, or deeply divided. 

 Petals definite, seldom wanting, alternate with the 

 segments of the Calyx, and equal to them in number, 

 generally with Claws. Stamens definite, sometimes 

 fewer than the Petals, but more frequently the same 

 in number, and alternate therewith, or twice as many,
