A NEW SOUTH-AFRICAN GENUS, 265 
a mass of countless myriads of the siliceous skeletons of many 
generations of minute Conferve, either identical with, or very 
nearly allied to, those of existing Diatomacee. The figures 
of both here given (see Tas. IX. B.), will show their close 
connexion. The botanist and the geologist may each con- 
gratulate himself that these minute particles have thrown 
new light upon an obscure corner of the wide field of his 
own researches; for while the former may prove their close 
alliance with existing vegetables, the latter may claim for 
them a place in the Fossil Flora, and rank them with the 
splendid discoveries of Ehrenberg. -

XV.—On a New South-African Genus of Plants, of the 
Order TuymELex, established by the omini 13 W. H. 
Harvey. 
[With a Plate, Tas. X.] 
Mr Harvey has done me the favour of communicating to : 
me flowering and fruiting specimens of a plant detected at 
Port Natal, South Africa, by Lieutenant-Colonel Peddie, of 
the 72d Regiment, allied to Aquilaria and Gyrinops; but 
. Which has so many of the characteristics of Daphne, that he 
is led to believe that the Order Aquilarinee itself should rather 
form a section of Thymelee, in which opinion Mr Arnott 
seems entirely to accord. Be that as it may, the plant in 
_ Question constitutes a Genus distinct from any either in Aqui- T ig 
— larineg, or in Thymelee, and to which Mr Harvey has given . 
the name of Peddiea, in compliment to its discoverer, who 
has collected in the same interesting country many otber E e 
novelties which Mr Harvey is preparing for een This Ex 
Genus may thus be characterized : — *
