654 Flora of the Malayan Peninsula. 



11. Bndopogon, Nees. 

 Fertile stamens 2 ; otherwise as Strobilanthes. — Species 20, in South 

 (or East) India, extending to Singapore. 



This genus is hardly worth re-establishing as a split-off from Strobilanthes, but 

 Lindau has introduced the point of " 2 fertile stamens only" into his diagnosis of 

 Pseudostenosiphoniinn ; so that it is necessary either to call Endopogon a genus or to 

 re-unite both in Strobilanthes. Strobilanthes is so very large that it is as convenient 

 to treat it under 4 genera as under 4 subgenera. 



1. Endopogon Eidleyi, C. B. Clarke, n. sp. Puberulous. Leaves 

 opposite, unequal, up to 6 by 2 in., elliptic, acuminate at either end, 

 subentire ; upper surface with scattered rhaphides ; petioles up to 1 in. 

 long. Pedimcles to •? in. long, one from each axil (i.e. in opposite 

 unequal pairs), each carrying one green strobilate spike, pendent 

 in flower, 1 to 1"5 in. long ; bracts '75 in. long, elliptic, acute, almost 

 papery, loosely but closely imbricate, adnate at the base. Floivers 2, 

 sessile, under each bract, without prophylla. Calyx '125 in. long, 

 5-fid to the base ; sepals pubescent, 2 lanceolate-linear, 3 linear. 

 Corolla -25 in. long in the bud (perhaps not much longer when ex- 

 panded), white. Stamens 2, fertile ; filaments glabrous ; pollen 60 by 

 40 /x, longitudinally ribbed. Ovary (and style) glabrous, with 2 ovules 

 in each cell. 



Singapore : Stagmount, Ridley 5987, 11255. 



Allied to S. adnatus, C. B. Clarke in Hook. f. Fl. Br. Ind. IV. 436, which is an 

 Endopogon. 



12. Strobilanthes, Blume. 

 Herbs or undershrubs. Leaves opposite, often very unequal, some- 

 times falsely alternate, crenate serrate or subentire ; the upper surface 

 usually full of rhaphides. Liflorescence various ; the flowers often in 

 heads or strobilate, sometimes solitary in lax panicles, sometimes in 

 small clusters which are panicled ; floral leaves prominent or small, 

 persistent or caducous, often passing into true bracts (" deckblaetter ") in 

 the upper part of a spike ; bracteoles (prophylla) 2, often similar to the 

 sepals, or wanting (but in the axil of a bracteole a bud is sometimes to 

 be found). Calyx of 5 (usually rather large) segments, subequal, 

 divided nearly to the base in the Malay species. Corolla tubular- 

 campanulate ; lobes rounded, twisted in the bud. Stamens (fertile) 4, 

 didynamous ; anther-cells 2, muticous ; pollen large, ellipsoid (rarely 

 subglobose), wuth 16 to 20 (rarely few) longitudinal ribs and 2 stopples. 

 Ovary oblong or ellipsoid with 2 ovules in each cell, sometimes stalked ; 

 style with one long branch, the other suppressed. Caf stile oblong or
