Calystegta. pentandiua moncgynia. 95 



ed. Bractes ovate, acute, much larger than the obtuse sub- 

 dentate calycine leaves, half the length of the corolla. Filaments 



glandular. 



Common in the valley of Nipal, along water courses, and simila 

 moist places; blossoming during the hot season. 



Root creeping, woody, perennial — Stems several, slender, angu- 

 lar, twining, sometimes running along the ground to a cousiderable 

 extent, as well as the other parts of the plant smooth. — Leaves from 

 one to two inches long, cordate, with a deep broad sinus, intermediate 

 lobe lanceolate, acute, lateral lobes triangular, divergent, with from 

 two to three broad bluntish teeth or lobes, which in the uppermost are 

 so deep as to give the leaf the appearance of being five or seven-lobed ; 

 when observed under a microscope their surface appears dotted with 

 transparent points ; those near the base of the plant sub-entire, oblong- 

 cordate. Petioles nearly equalling the leaves, furrowed. — Flowers rose- 

 coloured, solitary, on axillary, angular, thickish peduncles, which are 

 much longer than the leaves, the lowermost often measuring four in- 

 ches; those above gradually shorter. — Bractes opposite, ovate, sub- 

 cordate, acute, nerved, obscurely crenulate, almost concealing the 

 calyx, which consists of five membranaceous unequal leaflets the ex- 

 terior ovate-obtuse, the inner ones smaller, lanceolate-acute.— Corolla 

 twice as long as the calyx, with a five- lobed, bluntish border, each lobe 

 ending with a few* short hairs. — Stamina nearly equal, reaching to 

 the middle of the corolla; filaments flattened, broader at the base 

 with a few glandular hairs ; anthers linear, erect. — Ovarium ovate 

 four-furrowed, incompletely divided into two cells by two opposite 

 parietal narrow septa which do not reach the axis; ovula four, erect. 

 — Style capillary, longer than the stamens ; stigma consisting of two 

 cylindrical slender obtuse lobes. 



Obs. This species is very much like Convolvulus arvensis (to which 

 as I have remarked above Roxburgh's C Malcolmii undoubtedly 

 belongs) in its stem, leaves, and in the colour and size of the flowers; 

 the calycine bractes easily distinguish them from each other. — N, W,
