2. Orthosiphon.] 106. LABIATM, 



1. 0. pallidus, Royle. * 



A small scarcely woody plant 4-12" high with many more or less 

 erect or diffuse branches from near the rootstock, sharply 4-angled 

 and puberulovis above. Leaves ovate or elliptic l-VW (-2", F.B.I.), 

 attenuate at the base, crenate- serrate with teeth often few, pale 

 beneath. Flowers racemed, about 6 in a whorl, "3^ long, deflexed with 

 pedicels erect or subpatent in fruit. Calyx glabrous within, many- 

 nerved, without long hairs but hispidulous outside, -25" long in fruit 

 with 2-awned lower lip about as long as the broad upper. Nutlets 

 pale globose (F.B.I, says compressed subglobose ; perhaps these were 

 not quite ripe). 



Shahabad, Hope ! Singbhum, frequent ! but not recorded from Chota Nag-pur in 

 Bengal Plants and probably often mistaken for an Ocimnm. The Central Provinces 

 may also be added to the distribution recorded in F.B.I. Fl., Fr. r.s.-Oct. 



Leaves glabrous except on the nerves beneath (or finely pubescent, F.B.I.), 

 mostly obtuse punctulate with glands, but nearly odourless, base narrowed into a 

 petiole •25-'4'' long. Racemes 2-4", whorls often dense. Calj'x '12" along both 

 upper and lower lips in flower, upper lobe in fruit "12" broad, broadlj'-oblong 

 rounded, those in a whorl often meeting one another as in Ovimum canum. Corolla 

 white. 



2. 0. rubicundus, Benth. 



A herb with stems 8"-20" high from a Avoody rootstock, Avhich has 

 also the roots sAvollen into turbinate tubers 1-3" long. Leaves 

 sessile or shortly petioled, oblong or elliptic-oblong, 2-4" long, 

 crenate or serrate coarsely puberulous or glabrate above, paler and 

 glabrous or hispidulous on the nerves beneath. FloAvers white, lilac 

 or rose in rather distant 6-fld. whorls on long terminal racemes 4-12" 

 long. Calyx "2" in floAver, '3" in frviit, minutely pubescent, upper 

 lobe sub-petaloid, purple. Corolla twice as long as calyx or up to 

 •5", tube about "S", pubescent. Nutlets suborbicular compressed^ 

 punctulate. 



Common in the forests of the Central Tract. Monghyr, Ham, ! Santal Parg. t 

 Throughout Chota Kagpur ! Probably throughout the Southern Tract, but speci- 

 mens onl^- collected from Kalahandi ! A specimen from Mayurbhanj, Hooper] is 

 referred to O. ii/curvits, Benth., in the Cal. Herb. The flowers are "G" long, but it is, 

 I tliink, this species. Fl. April-June, the shoots springing up after the jungle 

 fires. 



Stems sometimes tomentose, at others slightly pubescent only, 4-angled. Leaves 

 rarely 4-75" long, rounded or subacute at the tip, never acuminate, base usually 

 cuneate. Petiole 0-'25" on same individual. Bentham'^ variety rigida, however, is 

 characterised solely bj- "leaves petiolate." Calyx over 12-nerved at base in fruit, 

 upper lobe of lip only slightly decurrent on the tube, not forming a large shield on 

 it as in Ocimum, ■1-'12" broad in fruit; lower lip with 2 awns projecting beyond 

 upper, side lobes with shorter awns. Bracts sessile ovate or oblong reflexed,. 

 •05-*l". Stamens 2, upper not as long as the lip, 2 inferior included in tlie tube, 

 filaments glabrous. 



3. 0. incurvus, Benth. 



Closely resembling 0. rubicundus but the leaves acute or almost 

 acuminate tapering both ends, 3-4", coarsely crenate, sec. n. 4-6. 

 Petiole •7-1*'. FloAvers larger, -Q-S". Calyx •25''' in flower, •3--5" 

 in fruit, lower lip awned. Corolla blue or purple-red. 



Native of the sub-Himalayas, Assam and Silhet. Fl. July-Oct. 



A specimen from Mayurbhanj, collected hy Hooper, is called 0. inctcrvtis in the
