petiole entirely glabrous, 3-9 mm. long. Flowers terminal and axillary, 

 solitary, about 6-7 cm. across, white, semulouble. Sepals sericeous dorsally 

 and scales also more or less so. Petals sulmumerous, obovato-oblong or 

 oblong, emarginate or retuse, about 3J cm. long. Stamens numerous,

This differs from the type of Thca Sasanqua (Thunb.) Nois. by the 

 glabrous branch, larger and more shining leaves, entirely glabrous petiole, and 

 dowering time ; probably a hybrid between Thea Sasanqua and T. japonica 

 with the characters of T. Sasanqua more predominating. 



Dendrobium tosaense Makino. 111. Fl. Jap. I. n. S (1891) p. 1, 

 tab. 46. 



An epiphytic orchid. Rhizome not long, creeping, densely rooting, 

 attaining about 4cm. long; roots fibrous, filiform. Stems few to several 

 to a rhizome, closely placed, tufted, elongate, slender, simple, many-articu- 

 lated, often somewhat contracted at nodes, many- foliate, but old ones 

 bare from fallen leaves, shortly and ovoidly thick at the base, 2-85 cm. 

 long, a new stem produced annually outside that of the preceding year ; 

 internodes cylindrical, scarcely enlarged above, sub-carnose, at length striate, 

 dark-purple or dark-viridescent within the sheath, about 1-4 cm. long. 

 Leives alternate, distichous, loose, lanceolate or narrowly lanceolate, acute, 

 shortly attenuated to a very short petiole or subsessile at the base, smooth 

 on the entire margins, glabrous, smooth, membranaceo-coriaceous, green 

 above, slightly lighter beneath, somewhat channelled in centre above, about 

 2i-7icm. long, §-l§ cm. wide, evergreen; veins close but inconspicuous 

 superficially in recent, transverse veinlets loose and not conspicuous ; sheath 

 membranaceous, closely enclosing the internode, viridescent with purpurascent 

 colour, but albo-cineraceous or cineraceo-avellaneous in age. Racemes lateral 

 on the upper and sometimes also middle portions of the stem, one to a node, 

 simple, laxly 2-5-fiowered ; rachis gracile, flexuous, smooth, glabrous, 3-7^ 

 cm. long, with membranaceous minute scaly sheaths at the base ; bracts 

 minute, subulate, acute, shorter than pedicels. Flowers medium-sized, yel- 

 lowish-viridescent. Perianth sub-patent, acute. Sepals: the upper one 

 lanceolate ; lateral ones broader, adhering with a large foot at the column 

 and enclosing the base of the label lum. Petals smaller than sepals, Ian-
