less so in the white-woolly form. In the two examples on one sheet marked by Nees' 

 hand Wallichii and tomentosa, the former has the connective conspicuously, the 

 latter minutely; excurrent. The East Himalaya examples are flowerless, and may 

 belong to ^E. tomentosa, type. The Chittagoug example is densely snowy-woolly with 

 6 hair/ seeds, and is therefore 2E. tomentosa, var. Wallichii, or a new species. 



2. 2E. Seiosperma, Clarke; hairy, leaves ovate or elliptic acute, 

 bracts linear- ligulate as long as the calyx, anthers oblong connective 

 excurrent at the tip, seeds glabrous. 



JAINTEA and E. KHASIA, alt. 3-4000 ft.; abundant, Clarke. 



A small shrub, 2-3 ft. high, very hairy, often viscid, with both brown and white 

 hairs. Leaves 3 by 1 in., rounded at the base, crenulate; petiole i in. Panicle 

 resembling that of 2E.. tomentosa, often somewhat leafy ; bracts \ in., linear-ligulate ; 

 bracteoles ^ in., similar to the bracts. Sepals ^ in., subequal, linear-ligulate, very 

 hairy. Corolla, stamens .and pistil as of M. tomentosa, but the connective more 

 excurreut than in any form of JE;. tomentosa. Capsule in., 6-seeded. Seeds much 

 thicker than in JEchmanthera, and without hairs. I cannot match these seeds with- 

 out going to quite another part of the Acanthaceous Order. They are glabrous 

 when wetted, not discoid. On the other hand, except the seeds, the plant is hardly 

 distinguishable from. &. tomentosa. There are abundant specimens with seeds 

 in situ. 



XVIII, STROBILANTHES, Blume, 



Large or small shrubs, or herbs. Leaves opposite, often unequal, in 

 8. anisophyllus often apparently alternate, toothed or subentire, often 

 bearing raphides. Flowers capitate, or in strobiliform or interrupted spikes, 

 or panicled, sessile or sometimes pedicelled, purple yellow or white ; bracts 

 and bracteoles large or small or 0, persistent or caducous. Calyx deeply 

 subequally 5-d ; or (in Sect. Buteraea) 2-lipped, with one lip very shortly 

 3-toothed ; segments narrow, equal or unequal. Corolla tubular-ventricose, 

 straight or curved ; lobes 5, ovate or round, subequal, contorted in bud. 

 Stamens 4, didynamous, or (in Sect. Endopogon) 2 ; anthers oblong, 2-celled, 

 muticous. Disc small, or prominent as. a stalk to the ovary. Ovary 

 4-ovulate ; style linear, stigma of one long linear-lanceolate branch, the other 

 suppressed. Capsule 4- or 2-seeded ; placentae (in a few species only) rise 

 elastically from the base, carrying the seeds with them. Seeds much com- 

 pressed, glabrous or hairy, hairs elastic when wetted ; retinacula curved, 

 strong. Species 180, Asiatic and 1 in Africa. 



This genus contains a great number of species differing widely in habit, inflores- 

 cence and size of the flowers. It is here limited to species with 2 ovules in each cell 

 of the ovary. All with more than 2 in each cell have been carried toRuellia, Echina- 

 canthus, Hemigr aphis, Stenosiphonium and JEchmanthera. 



Strobilanthes roseus, Wall. Cat. 7154, is an Ava plant, not known from British 

 India. 



Stobilanthes salicifolius, T. Anders, in Journ. Linn. Soc. ix. 484, is a plant of 

 altogether uncertain origin.
