calyx, acute. 
Stems erect, with few, opposite, acutely four- rigid branches ; 
general height about six inches. 
Leaves opposite, sessile, ovate- oblong, serrulate, three-nerved, 
acute, smooth. 
Flowers axillary, solitary, long-peduncled, small, general colour 
blue, though I have seen many plants with white flowers. 
Steril Filaments two-cleft: divisions capitate. 
Capsule oblong, pointed, longer than the calyx. 
Ts also a native of low, moist places over India, where it appears, © 
and blossoms during the rains. 
204. GRATIOLA ROTUNDIFOLIA. 
Linn. Spec. Plant. Edit. Willd. 1. p. 103. 
Annual erect, four-sided. Leaves sessile, round-cordate, ser- 
rate-dentate. Peduncles axillary, solitary, longer than the leaves. 
Capsules globular, length of the calyx. 
With the two former species, this appears and blossoms during 
the rains, and continues in flower the first part of the cool season. 
Willdenow quotes Tsjanga-puspam, Rheed. mal. 9. tab. 57, for 
this delicate small species; but I have found another, which I 
call G. integrifolia, that I think agrees better with that figure than 
this. 
205. HIPPOCRATEA ARBOREA. 
Subarboreous, with weak subscandent branches. Leaves oppo- 
site, elliptic, serrulate, fine-pointed. Corymbes axillary, dichoto- 
mous. Capsules linear-oblong, two-seeded. 
Cotta-paharia of the Hindoos. 
Trunk straight, about as thick as a man’s arm, covered with smooth, 
dark brownish, ash-coloured bark. Branches and branchlets 
spreading, and tending to climb ; young shoots round and 
smooth, indeed highly polished. 
Leaves opposite, short-petioled, drooping, elliptic, fine taper- 
pointed, serrate, very smooth on both sides; six or seven 
inches long, and about three broad. 
Stipules none, but two or three small, dark brown, scaly buds in 
each axil. 
Corymbes axillary, dichotomous, with a pedicelled flower in the 
divisions. 
Bractes opposite, small, permanent. 
Flowers very numerous, very small, pale greenish-yellow. 
Galyx beneath, generally four, though sometimes five, or even 
six-parted; divisions rounded, and only about half the length 
of the corol. 
Corol four, five, or six-petalled ; six is the most common, and I

suspect the natural number, in a double series ; equal, ovate- 
oblong, smooth. 
Nectary : a three-sided, fleshy cup, surrounds the insertion of the 
stamina and germ. 
Filaments three, membranaceous, shorter than the corol. 
four-lobed. 
Germ ovate. Style short. 
Capsules three, linear-oblong, compressed, smooth, one-celled, 
two-valved: each valve boat-shaped. 
Seeds two in the apex of each capsule, with a long, broad wing, 
extending to its base, where they are inserted. 
Anthers 
Stigma simple. 
A native of the interior parts of India, blossoms in July, and 
the seed ripen in March. 
A small tree of five years growth, and about twelve feet in 
height (in the Botanic Garden at Calcutta), reared from seed, pre- 
sented by Dr. Hunter, flowered in July 1802, for the first time. 
206. PANICUM SQUARROSUM.

p- 845. 
Culms creeping. Spikes two, horizontal ; rachis jointed. Flowers 
fascicled (from the upper end of each joint of the rachis). Corol 
three-valved. 
Cenchrus muricatus. Linn.Mant.302. Schreb. gram. 2. p.69.t. 34. 
Culms creeping to a considerable extent, with alternate spreading 
branches ; their flower-beari ing extremities ascending. 
Leaves short, but rather broad, and covered with soft hairs. 
Sheathes large, involving much of the culms, downy. 
Spikes two, terminal, spreading horizontally, or ascending in a 
curve, one-ranked. Rachis composed of from four to eight, 
thin, membranaceous, oblong joints ; a waved ridge divides 
them longitudinally on the inside. 
Flowers collected in sessile bundles, of from four to eight on the 
inside of the upper end of each joint of the rachis. 
Calyx one-flowered, three-valved: the exterior minute, and lJan- 
ceolate: the second large, acute, and striated ; the inner nearly 
as small as the exterior, tapering from the base to a fine point, 
three-nerved, and fringed with a scariose border. 
Is a native of the dry, sandy ground near the sea, on the Coast 
of Coromandel.
