 ADDENDA. 



While correcting fhe last sheet of the présent paper, I became aware of Iwo 

 important publications that I must mention hère. 



The first one is written by Messrs. Eberhardt and Aufray (1918) and chiefly 

 contains an analysis. botanical and chemical, of the teas made in Indochina, illustrated 

 by a great many drawings of leaves and leaf fragments. Hère our eye is struck by a 

 leaf 126X48 mM. from Môc-châu, and one of 174X67 mM. from Laos (Mieng-luang) t 

 The authors report (p. 1004) that, „d'après des renseignements récemment reçus 

 Je the^ consomme au Laos par les indigènes provient uniquement d'arbres sau^ 

 «vages. ..Ces arbres seraient représentés par deux espèces: lo le Mieng-luang très 

 «abondant dans les bassins de la Nam-sang et de la Nam-bon (Muong de Vientiane) 

 ..dans le Tasseng de Natho (Vang-vieng) ainsi que dans la région de Tourakhom' 

 «Cette variété est cueillie en forêt, mais s' acclimate bien sur le bord des Houei.-2o 

 ,.le Mieng-noi ou Mieng-kay, moins abondant que le Mieng-luang se rencontre presque 

 exclusivement dans les terrains élevés et en forêt; très répandu dans le Muong de 

 „Vang-vieng et de Borikhane, sa production est au contraire insignifiante dans le Muong 

 „de Vientiane." The latter région seemingly produces smaller leaves than the former 

 Besides, the authors describe tea of a glabrous type coming from the plateau of Trân- 

 ninh. Ail the localities cited hère are situated in the Laos country S E of Luang- 

 prabang, so that they connect the Tong-king tea habitats with Eastern Siam where 

 tea has not yet been found. In fact, our conceptions of (large-leaved) wild tea being 

 restricted to Assam and Manipur are entirely overthrown by the récent discoveries 

 in the Freiich colonies! 



ni ""'^^ ^'^^ *''^^' ''^"°''^'"g *o ^he authors, thèse Laos teas are manufactured in 

 he Chinese way, being dried and then rolled; I suppose they are not eaten, asleppett- 

 tea, so hère we meet with the same problem as on p. 220- 



The second paper mentioned is the Sth volume of Mr. Hayata's Icônes planta- 

 rum Formosanarum. Desiring henceforth to employ the correct generic name Camellia 

 [^^^P/'ses (p. 11) the species „Thea- hozanensis and Nakaii, first published by him 

 in 1918 (p. 2 and 3) and also reduced by me to Camellia in the présent paner (p 240) 

 As a matter of course the priority of this change is now to be attributed to Mr Hayata 

 himself, so that thèse species hâve to be indicated thus: Camellia hozanensis Hay and 

 C. Nakaii Hay . 



Further Mr. Hayata identifies his species „Thea biflora'' (1911, p. 44) with Ca- 

 mellia oleijera Abel, which species is by some botanists referrcd to C. Sasanqua by 

 others to C. drupifera. In my détermination table (p. 243) I had tentatively put it 

 under 13, near C. drupifera. Perhaps Mr. Hayata would, on doser inspection and com- 

 parison, unité it with C. drupifera. 



Finally, the Japanese botanist gives two new species: Co;w//w/7oA-oe/2s/s Hay. (p. 10) 

 and C. transnokoensis Hay. (p. il). The former should in my opinion be classed in 

 the section Eucamellia and might be placed under 14 (C. yunnanensis and tenuiflora) \n 

 my détermination table. The other nova species belongs to the section Theopsis sub 

 26 (C. cuspidata and Costei, perhaps even identical with the latter, as far as I can 

 judge, although its type spécimen was only found in Kwei-chau, C. China)— 



Mr. Hayata compares C. nokoensis to „Thea transarisanensis Hay.". The latter is 

 a nomen novum for „Thea parvifolia Hay." (on account of this name having been 

 used by Salisbury (1796) in another sensé) and was accordingly published as such by 

 Mr. Hayata in his „lcones" V (1915). Ignoring this synonym, I reduced „r//ca" to 

 ^Camellia parvifolia (Hay.) C. S." in 1916 (p. 68); of course my dénomination is non- 

 val id. But I allow myself on this occasion to rebaptise the species on hand Camellia 

 transarisanensis (Hay.) C. S. As to the relationship between this species and C. /2oÂ:oe«s/5, 

 I do not think it very probable-
