44 CXIX. POLYGONACEX. (J. D. Hooker.) | [ Polygonum. 
7-10,000 ft., J. D. H., &e. Kuasta Mrs, alt. 4-5000 ft., Lobb, J. D. H. & T. T., 
&c.—DISTRIB. Java. 
Annual. Stems 10-18 in., slender, flaccid, grooved and angled, strict or flexuous, 
simple or branched. eaves 13-6 in., membranous, ciliolate, glabrous or sparsely 
hairy, uppermost simple and cordate-amplexicaul ; lateral lobes 1-3 pairs horizontally 
spreading, rounded or oblong ; auricles very variable, sometimes in mere green rings, 
at others nearly 1 in. diam.; stipules short, hairy and ciliate. Peduncles slender. 
Heads 3-3 in. diam.; flowers white or pink.’ Perianth 5-cleft. Stamens 7-8. 
Styles 3, slender, connate below. Nut opaque.—The var. B. javanicum has much larger 
more ovate trigonous nuts.—Extensively cultivated in Sikkim. 
46. P. sinuatum, Royle mss.; Meissn. in DC. Prodr. xiv. 1. 130; 
glabrous, stem creeping with short erect leafy branches, leaves runcinate- 
pinnatifid, terminal lobe rhomboid acute, petiole short with amplexicaul 
auricles, peduncles glabrous axillary, heads solitary, involucral leaf 0, bracts 
ovate obtuse, nut minute globosely trigonous. 
WESTERN HIMALAYA; Kumaon, Royle, alt. 9000 ft., Strachey d Winter- 
bottom; Garwhal, Falconer ; Kulu, alt. 8-10,500 ft., Stewart. 
Perhaps, as Meissner suggests, a variety of P. runcinatum, but creeping, much 
smaller in all its parts, and quite glabrous except occasionally the stipules, Jeaves 
4-1 in., terminal lobe much smaller in proportion to the lateral and of a very different 
shape, sometimes almost transversely oblong and apiculate. The nut is the same in 
both. 
47. P. capitatum, Ham. in Don Prodr. 73; stems or branches many 
stout creeping from a woody rootstock leafy, and stipules glandular-hirsute, 
leaves 3-13 in. shortly petioled elliptic acute, petiole 2-auricled at the base, 
stipules short cupular, heads 1-3, peduncles glabrous or glandular-hispid, 
involucral leaf 0, bracts ovate acute eciliate. Meissn. Monog. Polyg. 82, 
. and in DC. Prodr. xiv. 1.129; Bab. in Trans. Linn. Soc. xviii. 107. 
repens, Wall. Cat. 1699; Meissn. in Wall. Pl. As. Rar. ii. 60. 
SUBTROPICAL and TEMPERATE HIMALAYA; on rocks, walls, &c., alt. 4-6000 ft., 
from Chamba to Bhotan. Kuasia Mrs., alt. 3-5000 ft. 
Perennial; rootstock stout, twisted ; stems or branches 6-10 in. long, trailing and 
rooting below, red-brown; hairs brown. Leaves crowded, bifarious, rather thick, . 
brownish when dry, eglandular, base sometimes cordate; petiole 4-4 in., auricles 
small rounded. Heads 4-3 in. diam., dense-fid., glandular and hairy; bracts glabrous. 
Perianth pink, 5-cleft; segments obtuse. Stamens 8. Nut 8.gonous, very small, 
yz in., much smaller in proportion to the perianth than in its allies —Meissner’s var. 
macilentum appears to have no definite character. 
48. P. chinense, Linn.; Meissn. in DC. Prodr. xiv. 1. 130; shrubby, 
glabrous or sparsely pubescent or glandular-pubescent, leaves petioled 3-5 in. 
from linear-oblong to oblong- or deltoid-ovate or -rotundate entire or cre- 
nulate, base truncate rounded acute or subcordate uppermost cordate 
amplexicaul, petiole hardly winged usually 2-auricled at the base, stipules 
long very obliquely truncate acute, heads panicled or corymbose, peduncles 
usually glandular-hairy, involucral leaf 0, bracts glabrous usually acute, 
fruiting perianth dry or fleshy, nut trigonous. Meissn. Monog. 60, and in 
Wall. Pl. As. Rar. iii. 60; Bab. in Trans. Linn. Soe. xviii. 109; Roxb. Fl.
