pubescent ; lower lip with central pair of teeth minute and mucli 

 shorter than the upper lip, which is rounded and recurved. Corolla 

 •17 in. long, yellowish- or greenish- white, externally pubescent. Fila- 

 ments distinctly exserted ; upper pair with a bearded tooth at the base. 

 Nutlets -06 in. long, subglobose, rugose, brown. Eoxb. Fl. Ind. III. 17 ;

Penang : Wallich. Almost certainly only cultivated in our area.- — 

 DisTRiB. Tropics generally, but doubtfully indigenous in America. 



The only record of this species from our area is that of Wallich, who collected 

 specimens in Penang in 1822. Seeing that no one has sent it since from any of 

 the provinces, it may almost certainly be concluded that Wallich's specimens came 

 from cultivated plants or from casual escapes that have not become permanently 

 established. 



2. Orthosiphon, Benth. 



Herbs, undershrubs, or shrubs. Floivers in 6- or fewer-flowered 

 racemosely arranged whorls ; bracts small. Calyx 2-lipped, ovoid or 

 campanulate-tubular, deflexed in fruit ; lower lip 4-toothed, the central 

 and lateral teeth distinct or shortly connate, usually subulate ; upper 

 lip broad, membranous; the margins decurrent. Corolla 2-lipped; 

 tube often slender, straight or incurved ; lower lip entire, concave ; 

 upper lip 3- to 4:-fid. Stamens 4, declinate, didynamous, included or 

 exserted ; filaments free, not appendaged at base ; anther-cells con- 

 fluent. Dish usually gibbous. Style with a small capitate or clavate, 

 entire or notched stigma. Nutlets dry, ovoid or globose, smooth or 

 nearly so. — Distrib. Species about 60, in Tropics of the Old World. 



Orthosiphon stamineus, Benth. in Wall. PI. As. Ear. II. 15 (1831). 

 A slender glabrous or pu^jescent herb, 1 to 2 ft. high; stems distinctly 

 quadrangular. Leaves opposite, membranous, usually puberulous to 

 pubescent on the nerves on both surfaces, otherwise glabrous, rather 

 dark-green above, ovate-acuminate, with long entire cuneate base ; 

 margin elsewhere coarsely wide-serrate ; 2 to 4 in. long, -75 to 1'5 in. 

 wide ; petiole "25 to "4 in. long, puberulous or pubescent. Floivers in 

 rather distant whorls, "6 in. apart below, these arranged in lax terminal 

 racemes 4 to 8 in. long, 1*5 in. across, not including the far-exserted 

 filaments. Calyx "15 in. (in fruit -25 in.) long, campanulate, pubemlous 

 on the nerves, gland-dotted between ; the two central teeth of lower 

 lip subulate. Corolla uniformly finely puberulous, 1 in. long, purpHsh 

 or white ; tube slender, straight, thrice as long as calyx ; lower lip 

 straight, -2 in. long; upper lip refracted, '2 in. long. i^«7a.me?i^s glabrous, 

 capillary, projecting 1-2 in. beyond coroUa-Hmb. Nutlets wide-oblong, 

 compressed, rugulose. Benth. Lab. Gen. & Sp. 29, and in DC. Prodr. XII,
