CARL SKOTTSBERG, A BOTANICAL SURVEY OF THE FALKLAND JSLANDS. 



sandy heath; Westpoint Island! in the heath. — Fuegia (/?. fueginos (!) Phil. =7?. 

 philippianus de Wild.). 



116. R. trullifolius HooK. fil. p. p. qiioad plantam anno 1844 descriptam, non 

 1879 nec auctt. sequent. (? R. monanthos Phil.) 



As I have mentioned above, this species 

 was desoribed in Fl. ant. p. 226 on insufficient 

 material; the single flower found was incomplete, 

 and it is quite easy to understand that the author 

 himself låter mistook R. pseudotrnUifolhis for this 

 species. However, it is not difficult to distinguish 

 them, even without flowers. Their growth is the 

 same, but the texture of B. trullijolius is firmer 

 and its colour mucli darker, a dark green or even 

 slightly brownish (»luride viridis vel purpura- 

 scens», as HooKER accurately expresses himself). 

 Stolons are less developed than in R. pseudo- 

 irullijolins, and shorter on my specimens. Leaves 

 long petiolate, 2—6 cm.; lower half of petiole 

 sheathing ; sheath broader than in R. pseudotrulli- 

 jolius (8—10 mm.), abruptly narrowed above, sometimes ending in a tiny tooth on 

 each side, subscariose, brown and glossy. Blade 10 — 12x6—8 mm., obovate-obcuneate, 

 more gently narrowed at the base, apicall}^ abruptly truncate and irregularly 3—5 

 dentate, dents sliort, more parallel, more acute, all of the same length or the middle 

 one slightly longer, subcoriaceous, glabrous or with a few coarse hairs in the margin.

Primary leaves with entire blade or nearly so. Flowers solitary on a comparatively 

 long peduncle (1 — 4 cm.), c. 7 mm. across. Sepals 5, reflex, slightly cucullate, ovate 

 obtuse, 3 — 3,5X1,5 — 1,75 mm., with midrib alone distinct; petals 5, yellow, spathulate, 

 irregular nervöse, with glandular pit in the middle, 4,5x1,5 mm. Stamens c. 9, 3 mm. 

 long, carpels c. 7, immature 2, mature 3 mm. long; style very short, erect, with small 

 stigma. — Pl. III, Fig. 4—5.
