THE GENUS CANEPHORA 77 



medium ramosus; rami inferiores steriles; spicae longiores et 

 laxiflorce spiculis saepe non contiguis; bractea exterior herbacea 

 margine meiiibranacea, /erg glabra; bractea interior quam bractea 

 exterior ixiullo i^lus duplo longior, fere glabra; calyx tenuior, 

 multo minus hirsutus; calycis lobi breves, triangularo-ac?6^i. 



Plant very sparingly finely hairy, rarely almost glabrous. 

 Leaves usually slightly emarginate, not showing white tubercles 

 when dry. Scape often more or less glabrous in upper part, 

 branched from below the middle, numerous sterile branches usually 

 present. Spikes rather long and usually quite lax-flowered, often 

 with spikelets not contiguous (as in L. humile Mill.). Spike- 

 lets usually 1-flowered. Outer bract herbaceous with a broad 

 membranous margin, apiculate or not, glabrous or almost so. 

 Middle bract 1|— 2J mm. long. Inner bract 2f-3J mm. long, 

 glabrous or almost so, a little more than twice as long as outer 

 bract. Bracteole 1 (rarely 2), 2|— 3^ mm. long, glabrous. Calyx 

 4:-4| mm. long, more slender than that of tomentellum, irregu- 

 larly hairy in lower half (not usually any higher) on veins and 

 sparingly between same, some veins wholly glabrous ; calyx- 

 lobes short, but usually slightly longer than those of tomentellum 

 (J mm. or more), triangular-acute. 



Distribution. — European Russia, E. & S. E. (Gouvs. Saratoff ! 

 and Orenburg !) Sarepta ! 



It will be noted that all the localities for L. tomentellum and 

 variety are inland.

THE GENUS CANEPHOEA. 

 By H. F. Wernham, B.Sc. 



I. The Genus. 



This genus of Bubiacece is, so far as is known, confined to 

 Madagascar; three species only have been described hitherto. An 

 examination of the material available in the British Museum and 

 Kew herbaria has suggested the necessity for some enquiry into 

 the definition and affinities of the species. 



Canephora was described originally by Jussieu [Genera Plan- 

 tarum, p. 208, 1789) as follows : — " Canephora. Flores 3-6 intra 

 calicem communem sub-5-fidum, sessiles squamulis distincti. 

 Singulis calix 5-6-fidus. Corolla parva campanulata 5-6-loba. 

 Antherae 5-6 oblongue sessiles. Stigma 2-fidum. Fructus .... 

 pisiformis coronatus 2-spermus. Frutex ; pcdunculi axillares soli- 

 tarii, a basi ad apicem incrassati, desinentes in calicem communem
