atid is, therefore, of a prior date; atid presumably the majority of 

 botanists follows this reasoning. But, keeping within the provisions of the 

 international riiles '). we ought to agrée with the British authors, who do 

 not look back prior to the first édition of Linnaeus' Species plantarum 

 (1753), and argue that only CaineUia was at that time accurately described ^). 

 And since the first author who united thèse two gênera (Sweet in 1818) 

 did so under the name of Camellia, art. 46 of the international rules^) 

 décides in favour of his choice. Kuntze **) adopts the name Thea because 

 in Linnaeus' enunieration of 1753 it précèdes Cam^///a; he very emphatically 

 insists upon the value of this ,,typographical" argument, as we might call 

 it, but the international congresses of botanists hâve decided otherwise. 

 Moreover he thinks that Hofmannsegg (1824) was the first to umte Camellia and 

 Thea under the latter name, but we know that Link (1822) and Sweet (1818), 

 and essentially even Sims (1807) had vQduced Thea io Camellia much eavUer. 

 With as m u c h c e r t a i n t y as w e c o u I d unité Thea 

 with Camellia, w e m a y, therefore, déclare that the uni- 

 ted g e n u s s h u 1 d b e n a m e d Camellia (L.) Sweet. 



Having established the correct generic name of the tea plant, we 

 hâve to pass to a review of the morphological relations between its allies. 

 I investigateii the genus in the herbaria of Buitenzorg, Utrecht, Leyden, 

 Berlin, Kew and Singapore. In the subjoined enumeration of species at first 

 those of KocHs's monography (1900) are recorded, and next a Ust of new 

 species in chronological séquence with référence to the authors.

to the remarkably deciduous petals; but, as only the former has been published, 



this must be used, though the iatter is more characteristic.
