Wight Ic. t. 1493. 
C W. Deccan PENINSULA, from Malwa (Edgeworth) to Mysore; frequent in the 
oncan. 
Rootstock woody ; stems 4-16 in., procumbent or creeping. Leaves 1-1 in., from 
lanceolate to orbicular, entire, minutely strigose and with long lax white hairs, lineo- 
late with raphides, nearly glabrate or minutely closely tomentose beneath; petiole 
0-3 in., but in some basal leaves 3-1 in. Spikes dense, white-strigose; bracts + in., 
elliptic ; bracteoles ł in., oblong. Sepals i in., linear. Corolla 4-1 in.; tube ven- 
tricose upwards, limb long, deeply 2-lipped. Style hairy. Capsule i in., 8-10- 
seeded, — The figure of Wight (Ic. t. 1493) shows the 4 anthers subequal, but this is 
not the case in his example from which he notes his Icon was taken. The synonym, 
Ruellia polysperma, Roth, has been always supposed to have been Hygrophila poly- 
sperma, T. Anders.; but as Roth says his plant had didynamous stamens and ovate 
heads, his description must belong here, whatever his plant was.—The leaves of Z. 
Serpyllum vary very much in form and indumentum. 
Var. Hookeriana; leaves orbicular obtuse cauline often distinctly petioled.— 
Physichilus sp. nn. 2, 3, Herb. Ind. Or. H. f. & T.—Concan ; Stocks. Bombay, 
Law. A larger plant; cauline leaves often 1 in. diam., petiole À—i in., with minute 
white bristly hairs, but none of the long white hairs characteristic of H. Serpylium 
type. 
3. H. Stocksii, 7 Anders. ms.; cauline leaves petioled spathulate- 
elliptic, spikes ovate or shortly oblong, anthers of the posterior stamens 4 
the length of the anterior.—Physichilus n. 4, Herb. Ind. Or. H. f. & T. 
Concan; Stocks. 
, Branches 18 in., stout ; internodes 2-3 in. Cauline leaves 24 by 1 in.; petiole 
Yin. Corolla } in. Anthers of the posterior stamens minute, but (at least some- 
times) they appear to contain a few pollen-grains.— Reduced to a Var. of H. Serpyl- 
tum by T. Anders. (in Journ, Linn. Soc. ix. 456), but subsequently marked by him as 
species.
