Asm.: Bonjora; Kh.: Soh-nari-khia.
Scandent shrubs, spinous; young parts finely pubescent to tomentulose; stem cylindric, gland-dotted; spines 5 - 20 mm long, recurved, tomentose; bark grey, lenticellate. Leaves simple; petioles 5 - 12 mm long, rather strong, inarticulate, slightly swollen near point of attachment below leaf blade, pubescent or glabrous; leaf blades elliptic-oblong to oblong-lanceolate or elliptic-obovate, rounded, sometimes also subcordate or rarely cuneate at base, abruptly and obtusely acuminate with 5 - 8 mm long acuminate at apex, entire along margins, coriaceous, dark green above, paler beneath, pubescent or minutely hairy beneath, glabrous otherwise; secondary nerves 6 - 12 pairs, faint above, rather prominent beneath, obliquely arching upwards, finely reticulate. Bracteoles 2, deltate, ca 0.5 mm long, densely pubescent abaxially, glabrous adaxially; pedicels short, ca 5 mm long, finely tawny-pubescent. Flowers axillary, in 2 - 3-nate clusters or sometimes solitary, to 14 mm long. Calyx ca 5 mm long, deeply 5-lobed; lobes deltoid, acute, ventrally, ca 1 mm long, pubescent dorsally, glabrous within. Petals 5, elliptic, obtuse, to 12 mm long, glabrous, white. Stamens 10, subequal; filaments linear-subulate, to 10 mm long, glabrous; anthers oblong, ca 3 mm long. Ovary seated on a distinct gynophore, oblong-ovoid, ca 1.5 mm long, finely pubescent, 5-locular; style filiform, ca 10 mm long, pubescent at 1/4 below, glabrous above; stigma capitate. Fruiting pedicels very stout, to 5 mm long. Berries globose, pellucid-punctate, dark green (unripe), 4-locular with a oblong solitary seed.
Distrib. India: Evergreen forests at lower elevations, 90-150 m. Tripura, Assam, Meghalaya, Orissa and Andhra Pradesh.
Fl. Feb.- April; Fr. Sept.- Dec.
Myanmar, Thailand and China.
Notes. P. scandens has superficial resemblance to P. monophylla but differs in its finely pubescent to tomentose branches and foliage and smaller flowers (8 - 14 mm long) with minute, deltoid, acute sepals. This species can be distinguished from P. citrifolia by its stamens with filaments longer than anthers and the indumentum of vegetative parts.
