Anthisiiria. triandria digynia. 553 



AccEssAKY Florets six, all male — Calyces two-valved, the 

 exteaior one of the four sessile tL rets papillose, ciliate near the apex. 

 ■ — Carol of one transparent valve. — iitamens three. — Pistil none. 



3. A. scandens. li. 



Perennial, ramon-, scandent, geniculate, emitting roots from the 

 j:Mnts. Floral ieavea wiili the base ciliate. Panicles copious, shag- 

 gy. Involucres smooth. Accessury Jiorels two-valved, neuter ; 

 exterior \alve of the sessile four, papillose, cihate near the apex. 



A native of Bengal; tloweis during the cool season. 



Root perennial. — Culms scandent, running to an extent of many 

 feet, smooth, ramous, jointed, and coloured, from the joints numer- 

 ous roots issue, and enter the ground if not too far removed from 

 it. — Leaves ensifonn, the tiorai ones much shorter, and ciliate at the 

 base. — Panicle terminal, composed of erect rami6cations of numer- 

 ous, rather remote fascicles of axillary, short pedicelled umbellets, 

 each of which is furnished with a boat-shaped spathe or bracte, 

 and consists of four, sessile, neuter, two-valved florets in a verticil ; 

 above these are two more, but much smaller, on short pedicels, 

 with one sessile, avvned, hermapnrodite one in the centre, on a 

 short scaly receptacle. — Calyx two-valved, the exterior valves of 

 the lower four neuter florets bearded, of the hermaphrodite ones 

 boat-shaped, and very obtuse. — Carol of the hermaphrodite flow-

06v. It diff'ers from A. ciliata in being an extensively scandent, 

 perennial plant.
