MAGNOLIACEJE. 173 



as concave as that of the Cdlijcanthea;, and that these last have 

 always opposite leaves. But it may be said that the floral recep- 

 tacle of a Magnolia, if pushed down so that its organic apex would 

 be at the bottom of the cup thus formed, would become exactly that 

 of a Calj/canihus ; and long ago the striking resemblance of the 

 flowers of Chimonanthus, those of lUicium and ^cJiizandra was re- 

 marked. The herbaceous ManunculacecB may also recall the struc- 

 ture of the flower of Magnolia, e.g., Myomrus and the Crowfoots with 

 an elongated receptacle. Tn the eyes of several authors the order 

 Magnoliacea have representatives among genera with unilocular 

 ovaries and parietal placentation. Such was Magna, which is 

 now-a-days restored to the order Bixacea, and which presents 

 numerous affinities with the Canellece. In this last series we find 

 genera with flowers closely analogous to those of some Samgdece, and 

 one plant whose habit, foliage, inflorescence, and gamopetalous co- 

 rolla closely recall what is observed in Ebenacea, which are moreover 

 closely allied to the neighbouring group, the Anonacea. Finally, 

 the Euptelea include two genera of which it was at first possible to 

 place the one, Trochodendron , among the abnormal Araliacece, while 

 the other, En pi el ea, presents more than one analogy, especially in its 

 diclinous flowers and samaroid carpels, with some of the Xanthoxg- 

 lacacece and Shnaruhece, like Ailanlhns, 



Of about seventy-five species belonging to this order nearly three 

 quarters are found in the Old World. All the Canellacea were 

 American, until the discovery of Cinnamosma. All the ScJiizandrccp, 

 on the contrary, except the species taken as the type of the genus 

 Schizandra, are foreign to America. The only three known Enpfelea 

 are Japanese. The species of IlUcinm are equally divided between 

 both Worlds. Drinujs is found in the whole of tropical and southern 

 America, and from Borneo and the north of Australia to New 

 Zealand. Among Magnoliece, Liriodendron is the only exclusively 

 American genus. The genus Magnolia is only represented in 

 America by the Emnagnolias and some Talaumas. Australia has no 

 Magnoliacea, except the section Tamnannia of Brinigs. No represen- 

 tatives are known native in Europe and Africa.' Thus, of the 

 eleven genera we admit in this work, four are common to both 



" Nor the iidjaccnt islands." (R. Br., Con^o, 465.)
