116 NAT UB AL HISTORY OF PLANTS. 



1866, Seemann 1 had the credit of restoring in one and the same 

 genus Phaleria (Drymispermum) and Lcucosmia of Bentham; 2 a 

 union fully adopted by this conscientious observer. 3 Miquel long 

 since, in 1861 and in 1863, enriched this series with the genera 

 SkapMumf Laclmolepis 5 and Gonistylusf the two former of doubt- 

 ful position, and the last intermediate, in the form and dimensions 

 of the floral receptacle, between the Aquilarieœ formerly known 

 and the genus Octolepis proposed some years since by Oliver. 7 



The thirty-three genera whose autonomy we admit comprise 

 about two hundred and sixty species. Not two are common to 

 both worlds, and a dozen of them are American. The greater part 

 are monotypes and their total represent only some thirty odd 

 species, whilst about two hundred and fifty are peculiar to the old 

 world, and are distributed in twenty-one genera. None of the 

 Aquilarieœ (some score of species grouped in half-a-dozen genera) 

 belong to America, and all, except Octolepis which is African, are 

 natives of the warmest parts of south-eastern Asia and tropical 

 Oceania. The American Thymcleœ are nearly all from South 

 America. Only a couple of Daphnopsis and Direct are from North 

 America. The three genera Daplmopsis, Lagetta and Hargasseria, 

 are found in the Antilles, and the two latter are met with nowhere 

 else. Coleopkora, Funifcra, Lophostoma and Schœnobiblus have been 

 observed only in Brazil ; Lasiadcnia in the north of Brazil and in 

 Venezuela ; Gooclallia in Guyana ; Ovidia in the Columbian Andes 

 and Chili ; Drapetes in the Magellanic region. Among those that 

 belong to the old world there are genera, not rich in species, the 

 geographical distribution of which is quite as limited. Thus Ped- 

 diea is exclusively from Southern or Western Africa ; Dicranolepis, 

 from tropical "Western Africa ; Synaptolepis, from Zanzibar ; Stephano- 

 daphne, from the eastern isles of Africa ; Passerina and Arthrosolcn, 

 from southern Africa ; Darthron, from central Asia ; Dais, from 

 Madagascar and the Cape ; Kelleria, from Oceania ; Linostoma, from
