Sphagua, but also forming härd cushions with Abrotanella and Astelia. — Patagonian 

 chanriels, S.W. Fuegia, Staten I (all localities in the rainy zone). 



7. C. sagittata C A. V. 



Of very variable growth, forming dense, härd mats of few cm. height on sand, 

 becoming very stout and up to 2 dm, high in water. The flowers are much more 

 conspicuous than in the former species, bisexual, 2 — 2,5 cm. in diameter or occa- 

 sionally even more. Perianth leaves 7 — 8, greenish white with yellowish apex, fija- 

 ments duU green, anthers yellow, carpels greenish yellow with brown stigmae. There 

 are 50 — 100 stamens and 40 — 60 pistils. I have not been able to discover honey, 

 and the construction is that of a pollen-flower. As the anthers open, the filaments 

 bend backwards, so that as a rule no pollen will reach the stigma? ; besides, the sta- 

 mens are very little longer than the carpels. In the common cushion-form, the flowers 

 are exposed on the same level as the foliage, insects, such as beetles, are seen crawling 

 över the surface and visiting the flowers, which are rich in pollen.

Rainiiiculus L. 



*47. R. acaulis Banks et SoL. (R. stenopetalus Hook. Ic. plant. t. 677.) 



The flowers are ± 8 mm. across; the sepals are 5, the petals generally more, 

 up to 8, of ratlier variable shape and a little fleshy. The whole plant is only 2 — 3 

 cm. high, caespitose with creeping stolons and forming extensive patches. The leaves 

 are fleshy. 



By the courtesy of Dr. D. Petrie in Auckland, New Zealand, I got a good 

 material of this species from there, A comparison shows, that the styles in the 

 New Zealand plant are, as a rule, longer than in the Falkland one, but in all otlier 

 respects the two plants fully agree, so that I do not hesitate in referring my spe- 

 cimens to the true R. acaulis. 



W. F,, on the sliore among gravel, formed by fragments of shells; rare: Spring 

 Point! opposite Westpoint Island! — S, Chile (Port Montt), New Zealand, Auckland I, 



94. R. biternatus Sm, (R. exiguus d'Urv.) 



Flowers 6 — 8 mm, across. Sepals 5, reflex, ovate, obtuse, 4x2,6 mm,, brownish 

 green, petals 5, linear spathulate, sulphureous, 5,5x2 mm., claw distinct, 2x0,75 mm,, 

 above it a glandular pit, stamens 12 — 15, 2 mm, long, with green filaments and 

 sulphureous anthers, carpels (immature) brownish-green, about 20, not quite 2 mm, 

 long with slender neck and a short, recurved style, with long papillae; mature achenes 

 dark red, wit erect style. — 



Widely spread över both islands, especially on damp humus or gravel near the 

 sea, but also among grasses in moist meadows, and in running water, E, F,, I\It.
