LAUTIACEM. 449 



turned to the study of this order for De Candolle's Prodromus, 1 

 describing in detail all the species thereof. Ee admits most of 

 Nees' genera, and adds the four new ones Ampelodaphne, Bihania, 

 Sassqfridium, and Synandrodaphne. The total of the generic types 

 retained by us in the order Lauracece proper then amounted to 

 forty-six. To these 2 we have recently added the genus Putameia 

 of Dupetit-Thouars, 3 hitherto attributed to Proteacea. 



At the same time two small groups, considered by several authors 

 as distinct groups, namely Gyrocarpea 4 and Illiyerea, 6 were associated 

 by others, especially by R. Brown and Nees, with Lauracea. Von 

 Martius, in 1837, described 6 a genus which, though closely allied 

 to Gyrocarpus, lacked the wing to the fruit ; he named it Sparattan- 

 thelium. IlernandidJ had also been made the type of a small order 

 apart, 8 but in 1864 we pointed out 9 that it merely represented a 

 reduced diclinous type of Illigera ; and made it into a distinct series 

 of the order Lauraceae, which now consists of fifty-one genera, ex- 

 cluding those that are unknown, or that are doubtful members of this 

 order. 10 The number of known species, estimated in 1846 at 450 

 by Line-ley, and at 700 by Nees, was raised to 1050 in 1864 in 

 Meissner's Monograph. 



Nees 11 had already studied their geographical distribution, dividing 

 them into eastern and western, referring his Cinnamomeae, Camphorea,
