340 ST. HELENA 



Leaves sparse, sessile, cuneate-lanceolate, serrulate, hairy. 

 Panicles terminal hairy. A slender upright shrub with but 

 few erect branches. A native of the thick forest of the south 

 face of Diana's Peak ; the flowers are large and white. 



I. Roella huo folia. R. Shrubby sub-parasitic (or Dicksonia 

 arborescens}. Leaves sparse, sessiles numerous, linear, smooth, 

 very acutely serrulate. Peduncles (racoures) terminal, few 

 flowered. A pretty little ramous diffuse alpine plant found 

 in the top of Sandy Bay Ridge, chiefly on Diana's Peak. 

 Leaves crowded round the somewhat villous columnar branches. 

 The flowers white, with a tinge of pink and highly ornamental. 



E. Rosa-triphylla. R. Scandent ternate-leaved, large white 

 single rose. 



E. Rosa centifolia. Willd. 2. 1071. Common Rose. 



E. Rosa muscosa. Willd. 2. 1078. Moss Rose. 



E. Rosa chinensis. Willd. 2. 1078. 



E. Rosa semperflorens. Willd. 2. 1074. 



E. Rubus pinnatus. Willd. 2. 1081. Shrubby. Leaves pinnate, 

 leaflets five or seven, rarely three ovate-cordate lucid, strongly 

 veined, doubly serrate. Panicles terminate. Stems, branches, 

 petioles and peduncles armed ; tender shoots villous and hoary. 

 Bramble, the vernacular name on St. Helena, where it proves 

 a most noxious plant running over large tracts of the best land ; 

 on account of the rapidity with which it grows to a much larger 

 size than the common bramble of Europe (Rubus friticoseus}. 

 It has hitherto baffled every attempt to extirpate it. The roots 

 grow to a great size, and every bit left in the ground grows. 

 Stem scarce, and what there is grows to be as thick as a man's 

 leg sometimes. Branches numerous, very long and scandent, 

 when their apices rest on the ground they strike root and 

 produce other plants as in the other species of this genus. 

 The young shoots glaucous and downy, the bark of the old 

 dark brown ; all are well armed with numerous recurved 

 prickles. Leaves alternate, pinnate 6-12 inches long, leaflets 

 ovate and ovate-cordate, smooth doubly serrate. Petioles 

 and ribs armed. Stipules petiolary, ensiform. Panicles term- 

 inal, with their peduncles and sub-divisions armed and downy. 

 Brackes like the stipules. Calycine segments lanceloate, 

 nearly twice the length of the ovate, pink petals, and they are 

 rather longer than the stamina and styles. Berries in shape, 

 size and colour very like those of the common bramble, but 

 scarcely so palatable. Some of the old inhabitants say it was 

 brought originally from England for the common bramble 

 of that country ; others, and with greater probability, say it 

 was brought from the Cape of Good Hope. 



E. Runex vescicarinis. Willd. 2. 256. Bladder sorrel and Acetosa 



or common sorrel. 

 E. Runex paticuta. Willd. 2. 249, and one or two species, which 



Dr. Roxburgh had no opportunity of ascertaining. 

 E. Rula graveolens. Willd. 2. 542. Rue.
