3 line long; tube of corolla cylindrical, 3 lines long, narrower at the base for one third of 
its length, with a row of villous scales in the throat; segments linear-oblong, crispate 
along the margins, 24 lines long, somewhat twisted dextrorsely, rotate; stamens seated 
at the constriction of the tube; filaments slender; anthers included, acuminate, shortly

The Echites circinalis, Griseb. (non Sw.) is said by the authors of the * Genera Plan- 
tarum,’ ii. p. 725, to be a cultivated specimen of Holarrhena antidysenterica. 
The Echites circinalis, Müll, does not belong to this species: it is the Echites 
leptoloba, Stadelm. (Mitozus, nob.), and the Echites revoluta, A. DC. l. c. p. 457 (Ane- 
chites revoluta, nob.). 
A drawing of this species, showing its floral analysis, is given in Plate XXXIIL n.

A species differing from 4. circinalis in its leaves acute at both extremities, in its 
longer racemes, with pubescent peduncle, calyx, and corolla, in its more revolute sepals, 
and its corolla twice the size, with the tube scarcely ventricose.

A scandent plant, with slender hispid branches; the axils are 21—3 in. apart; leaves 
elliptic-oblong, acute at both ends, or obtusely acute and gradually more acuminate, 
very membranaceous, green above, sparsely subhispid, with hairs globular at their 
base, with fine nerves, paler and glabrous beneath, with black dots corresponding 
to the hairs of the upper surface, prominent yellow midrib, patently hirsute, nerves 
little prominulent, 2-3 in. long, 9-15 lines broad, on slender petioles 5-7 lines long; 
racemes axillary, longer than the leaves; peduncle slender, 43 lines long, bearing 
upwards 4-6 flowers on slender hirsutulous pedicels 6 lines long; sepals acutely lanceo- 
late, 14 line long, glabrous; corolla white, its tube slender, subpentagonous, twice the 
length of the sepals; segments obtusely ovate; stamens inserted in the middle of the 
tube; lobes of disk oblong, emarginate, half the length of the 2 ovaries; 2 slender terete
