Flora of the Malayan Peninsula. 665 



From the size, habit, and stamens of this plant it is almost certainly either a 

 GrjnuwHtacht/um or a Phlogacanthua. 



16. Phlogacanthus, Nees. 



Corolla-tube cylindric. Capsule narrowly ellipsoid, contracted close 

 to the base ; otherwise as Gymnostachyum. — Disteib. Species 12, in 

 India ; 1 or 2 extending a short way east. 



1. Phlogacanthus brevis, C. B. Clarke, n. sp. A branched under- 

 shrub, 12 to 18 in. long. Leaves : blade 6 by 3-5 in., broadly ovate ; tip 

 subobtuse; base shortly attenuate; nerves 6 to 7 pairs; petiole 1 to 1-5 

 in. long. Panicles terminal, 2 to 4 in. long, oblong ; bracts minute. 

 Sepals "15 to '2 in. long, linear, minutely pubescent. Corolla small 

 (only seen in bud), grey pubescent without. Stamens 2; anther-cells 2, 

 oblong, parallel, at equal height, muticous ; pollen 20 by 15 fi, longi- 

 tudinally banded. Pistil glabrous. Capsule 1 in. long, nearly -2 in. 

 wide upwards, subcylindric, obtuse, 8-seeded ; base narrowed. Seeds 

 flat, nearly -125 in. in diam. 



Perak : alt. 300 ft., Kincj's Collector 2884. 



The capsule is here typically that of Phlogacanthus, and not the parallel-sided 

 capsule of Gymnostachyum ; but the two genera may be united. 



17. Andrographis, Wallich. 



Herbs or very small shrubs. Leaves entire. Bacemes (or spikes) 

 1-sided, axillary and terminal, often compounded into loose panicles 

 with spreading branches ; bract very small, narrow ; prophylla hardly 

 any ; flowers solitary or in few-flowered, distant clusters. Sepals 5, 

 rarely more than -2 in. long, linear. Corolla small (about -5 in. long), 

 2-lipped ; base tubular ; limb white, spotted pink-purple in the palate. 

 Stamens 2 ; filaments hairy ; anther-cells 2, ovate, parallel, at nearly 

 equal height ; base acute (not spurred), with often a tuft of hairs ; 

 pollen 25 fi long, short-ellipsoid, with few very slender longitudinal 

 ribs. Style thinly hairy ; tip minutely bifid. Capsule narrowly oblong, 

 with parallel sides, seed-bearing nearly from the base, flattened from 

 the back of the valves. Seeds 6 to 12, stony, cuboid-ellipsoid, smooth, 

 glabrate, with rows of minute pits. — Distrib. Species 18, very closely 

 allied, in India ; 1 or 2 extending to China and Malaya.
