44 Eucepb-alozia 



18a. Cephalozia tuhulata (Tayl. et Hook, f.! Lond. Jouru. Bot. 1844, 

 J). 463) ex insulis Falkland, cum C. Lammersiana congruit liabitu, 

 florescentia dioica, etc.; differt autem foliis angiistioribus — ovalibus 

 (■75 X 55™°^), nee ovato-orbiculatis — lobis sublongioribns ; foliolis ra- 

 morum apicem versus semper fere prsBsentibus : bracteis periantbiisque 

 magis elongatis, bis a basi ultra medium celliiHs bistratis conflatis. — 

 Caules interdum in planum furcati, furcis subaequilongis, yel altera 

 breyiore — raro tarn una Cjuani altera brevi et ad florem c redacta. 



Undeiieares are very often present, even on flowerless branches of female plants. 

 They begin to appear a good way below the apes, and are ovate-lanceolate, nearly 

 equal to the leaf halved vertically. The uppermost become bifid ; and the innermost 

 involucral leaves, or bracts are three, nearly of equal size, the lateral ones being un- 

 equally — the medial (or braeteole) equally — bifid : all entu-e at the margin. — An ex- 

 tended view of the limits of species would probably oblige us to unite both C. Lammer- 

 siana and C. tubidata to C. bicitspidata, as subspecies.- — \^Jung. albula Mitt, in Hep. 

 Ind. Or., Journ. L. S. Nov. 1860, p. 93 (in montibus Khasianis subtropicis, alt. 2, — - 

 4,000 ped.) according tothe deseiiption, is exactly C. Lammersiana.']
