Mic/irlia," considered by nearly all authors as a separate genus 

 from Mii(//io/ia, has exactly the flower of M. Fi(/o, and the receptacle 

 also presents a naked interval between the stamens and the pistil. 

 But in certain species the carpels, instead of always containing 

 two ovules each/ contain a larger number'' in two vertical rows. 

 The fruit and inflorescence, too, are those of M. Fi(/o, and hence we 

 do not put all these plants in diflerent genera. Magnolia acumi- 

 nata" L. has flowers like those of the preceding species, but the 

 colour of the petals is yellowish green, covered with a glaucous 

 waxy bloom. There is no bare interval on the receptacle between 

 the androceum and gynseceum, and each carpel is biovulate. The 

 stamens, inserted on the conical portion of the floral axis, are 

 unequal, with anthers rather longer and broader than the filaments ; 

 their two cells, which as in M. Yidan, approach the edges of the 

 connective, are still introrse, as in all Magnolias ; so that we also 

 include in this genus TuUjjastrum, of which M. acuminata is the 

 type, and of which the characters are not sufiiciently marked to 

 justify its autonomy. 



* So that now this character cannot be called present another section, in which the ovaries con- 

 in as constitutinof a generic difference between tain either numerous ovules in two vertical rows, 

 Magnolia and Michelia. This fact we have or only three ovules. In this last case, the carpels 

 already established {Adansonia, vii. 8). More- are those of the biovulate Michelias, which also 

 over, Hooker & Thomson {Fl. Ind., i. 79) accidentally present three ovules.
