136 NATUltAL mSTOUY OF PLANTS. 



ternate bracts or leaves beneath the flower which termmates it. 

 The inflorescence then becomes exactly that of M. grandi- 

 flora.' 



Michelia^ considered by nearly all authors as a separate genus 

 from Magnolia, has exactly the flower of M. Figo, and the receptacle 

 also presents a naked interval between the stamens and the })istil. 

 But in cei-fain 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. Figo, and hence we 

 do not put all these plants in different genera. Magnolia acinni- 

 natd' 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 gyntcceum, 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. Yulan, approach the edges of the 

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

 include in this genus Tuli past rum, of which M. acuminata is the 

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

 justify its autonomy.
