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 
litter minutely, excurrent. The East Himalaya examples are flowerless, and may 
belong to Æ. tomentosa, type. The Chittagong example is densely snowy-woolly with 
6 hairy seeds, and is therefore ZE. tomentosa var. Wallichii, or a new species. 
2. HE. leiosperma, 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. KwastA, 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 14 in. rounded at the base, crenulate; petiole } in. Panicle 
resembling that of Æ. tomentosa, often somewhat leafy ; bracts } in., linear-ligulate ; 
bracteoles 4 in., similar to the bracts. Sepals lin., subequal, linear-ligulate, very 
hairy. Corolla, stamens .and pistil as of Æ. tomentosa, but the connective more 
excurrent than in any form of Æ. tomentosa. Capsule 4 in., 6-seeded. Seeds much 
thicker than in ZEchmanthera, 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 Æ. tomentosa. There are abundant specimens with seeds 
in situ. 
XVIII. STROBILANTHES, Blume. 
Large or small shrubs, or herbs. Leaves opposite, often unequal, in 
S. 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-fid ; or (in Sect. Buterza) 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. Dise 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 ; placentæ (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 to Ruellia, Echina- 
canthus, Hemigraphis, Stenosiphonium and ZEchmanthera. u
