Since Kochs's monography, froni which I hâve adopted 19 species, the 

 nuinber of species has increased until 40, i.e., iiearly the double. Consi- 

 dering the precariousness of the classification eveii of Kochs's few species 

 in the sections Euthea and Camellia, and his huddling up of the most 

 heterogeneous éléments particularly in the first section, in order to save 

 the ancient boundary-line, we are indeed forced to the conviction that 

 there can be no question any longer of retaining only two sections, dating 

 from a period when botanists knew but two species of Camellia and one 

 of Thea. And, that we hâve now to propose new lines of démarcation, 

 may be regarded as another proof that Camellia and Thea should be 

 united. Pierre') already distinguished six groups: 1. Euthea (sole species: 

 T. sinensis) 2. Piquetia (sole species: T Piquetiana), 3. Stereocarpus 

 (species: T. Dormoyauu nnd drupifera), 4. Camelliopsis (species: T, eiiry- 

 oides, caudata, salicifolia, assimilis, maliflora), 5. Camellia (species: T. 

 japonica, hongkongensis, reticiilata, Sasanqua), 6 Calpandria (species: 

 lanceolata, qiiiscosaura, lutescens). 



I can no more agrée with thèse sections ; T. Piquetiana and Dormoyana 

 do not in my opinion belong to the genus, and at ail events the latter 

 cannot be taken together with drupifera, but this species is closely related 

 to Sasanqua. Besides, in the fourth section, the species euryoides and 

 maliflora (= rosiflora) must not be coupled with caudata, etc. 



I think we may provisionally form only five rather definite groups 

 thus : 



Sectio 1. Eriandria-). Stamens -i-j united, deiisely hirsute at the 

 inner side. Ovary and style densely hirsute. Calyx permanent. Flower 

 shortly stalked. 



Sectio II. Calpandria. Stamens completely united, forming a tube, 

 glabrous. Ovary densely hirsute. Calyx permanent. Flower sessile. 



Sectio III. EuCAMELLiA. Stamens more or less united, glabrous. 

 Ovary generally densely hirsute, style glabrous. Calyx deciduous. Flower 

 sessile. 



Sectio IV. Theopsis. Stamens occasionally partly united, glabrous. 

 Ovary generally glabrous, style always so. Calyx permanent. Flower 

 shortly stalked. 



Sectio V. Thea. Stamens almost free, glabrous. Ovary more or less 

 liairy, style glabrous. Calyx permanent. Flower stalked. 



There is no difficulty in the détermination of the species in the sections 

 I, II and V; in IV it is often difficult, in 111 very much so, owing to the 

 numerous intermediate forms. To meet the need for the détermination of the 

 Camellia s known at présent, I subjoin a détermination table, which is far 

 from correct, it is true, but may probably render some service for ail that. 

 A serions defect is my not having seen several (10) species myself, while
