Flora of the Malayan Peninsula. 651 



1. Stenothyrsus Eidleyi, C. B. Clarke, n. sp. Upper leaf: blade 

 up to 8 by 2 in., obovate-lanceolate, acuminate at either end, acute, 

 nearly glabrous, entire, reticulate, full of rhapliides ; main nerves 12 

 pair, oblique; petiole 1*5 in. long. Peduncle 1 to 4 in.; thyrsus 

 interrupted at base, of 20 to 50 flowers, clustered in very small opposite 

 cymes ; bracts inconspicuous, setaceous. Calyx -175 in. long ; sepals 5, 

 linear, full of rhaphides. Corolla 1 to 1-5 in. long, blue ; tube cylindric, 

 narrow-campanulate in the upper half, minutely hairy. Stamens 4, 

 subsimilar ; filaments glabrous, connected in pairs ; anthers long, of 2 

 linear-oblong cells at equal height, pubescent, minutely 1- to 2-mucro- 

 nate at the base, connective mucronate at tip ; pollen globose, 40 yu, in 

 diam., longitudinally 20-ribbed. Style thinly hairy, with one oblong- 

 linear and one suppressed branch. Capsule (not ripe) narrowly ellip- 

 soid, glabrate, seed-bearing from the base, with eight ovate flattened 

 seeds. 



Peeak : Tambun Loh, Bidley 9770 ; Ipoh, limestone rocks, 

 Citrtis 3149. 



Ridley placed this plant close to Strobilanthes ; the numerous capsules are all 

 8-seeded. There are, on one sheet, three thyrsi 8 to 12 by 1 in., and one thyrsus 

 reduced (apparently accidentally) to a dense head. 



10. Hemigraphis, Nees. 



Herbs or undershrubs. Leaves opposite, subequal, often crenate, 

 sometimes lobed ; upper surface with rhaphides, which are sometimes 

 altogether obscure. Flowers in terminal spikes, or rarely in 1- to 

 3 -flowered small heads on axillary peduncles ; bract usually exceeding 

 the calyx, lanceolate or ovate ; prophylla linear, short or 0. Calyx 

 deeply 5-fid ; segments lanceolate-linear or linear, subequal. Corolla 

 tubular-campanulate, blue to white ; lobes rounded, twisted in the bud. 

 Stamens 4, didynamous ; anthers of 2 oblong, subequal, parallel, 

 muticous, glabrous cells; filaments glabrous, or the 2 longer with many 

 long hairs ; pollen rather large, from short-ellipsoid to oblong-ellipsoid ; 

 the 12 to 16 longitudinal ribs reaching to the poles ; stopples 2. Ovary 

 oblong, with 6 to 12 ovules, usually hairy at tip ; style shortly hairy at 

 base ; stigma of one elongate and one suppressed lobe. Capsule oblong 

 or linear-obovoid, slightly flattened, hardly stalked ; seeds 6 to 12, 

 ovoid, flattened, with much hygroscopic hair on the margin. — Species 

 30 perhaps, in South-east Asia and Polynesia. 



To this genus belong Ruellia repanda, Linn. ; R. Ravacensis, Nees ; R. nemorosa, 

 Zoll. ; jR. colorata, Nees ; and, as Bentham says, most of Nees' first section of 

 Ruellia,
