36 CARL SKOTTSBERG, A BOTANICAL SURVEY OF THE FALKLAND ISLANDS. 



The form of the leaves also coincides fairly well with Schultz' description, but 

 some of my plants have a mucli larger apical leaflet, whicli will be the case in v. 

 litoralis, but in other characters they resemble v. suhcarnosa. According to Schultz 

 G. hirsuia L. is not closely allied to C. glacialis. The latter has larger flowers, no 

 style and is perennial. Hovvever, it should be remembered that v. Scehrensii (Phil.) 

 O. E. Schultz has smaller flowers and a trace of a style. 



Flowers c. 6 mm. long, 6 — 7 mm. across, sepals broad ovate, brownish green, 

 petals obcordate with long claw, filaments greenish white, anthers sulphureous, pistil 

 påle green. When the flowers open, anthers and stigma are on the same level. 



Moist places, streams etc., fairly common in both islands. — Andes from Co- 

 quimbo to Fuegia, Patagonia, Staten I., Tristan d'Acunha, New Zealand, Auckland, 

 Campbell and Macquarie I. 



Draba L. 



D. falklaiidica HoOK. fil. 



RoBiNSON ! witliout fnrther remarks on the place, and never found again. — 

 Patagonian Andes, found both by Dusen and by myself. I have compared with 

 Hooker's type. 



40. D. fuuiculosa HoOK. fil. 



Dry places in the heath, near the sea, scarce. E. F., Hooker; Port San Sal- 

 vador (Halle!); W. F., Vallentin ex Wright, Port Philomel, Halfway Cove! — 

 Fuegia. 



Arabis L. 



36. A. macloviaua (d'Urv.) Hook. fil. (Brassica macloviana d'Urv., B. ma- 

 gellanica? Gaud. non Poir., Commers etc, A. macloviana Reiche Fl. de Chile I. 

 p. 122 p. p. A. »falklandina Hook.», Baill. Hist. des plantes III, Erysimum mac- 

 lovianum Gay ex Gaud. Freyc. Voy. Bot. p. 136.) 



There has been a great deal of confusion about this plant. In spite of the 

 statements made by d'Urville, låter authors identified the species with Brassica 

 magellanica Juss., which has nothing whatever to do with it and belongs to Sisym- 

 brium. In Fl. de Chile III, Suppl. p. 386—87, Reiche compared the descriptions 

 and came to suspect the existence of two different plants; lie quotes Dusen (1. c). 

 Hooker had aiready described both species very accurately in Fl. ant., so I cannot 

 understand, why there has been so much uncertainty of late years. 



Another question is, if it ought to be left as Arabis or transferred to Turritis, 

 the seeds forming 2 distinct rows. The limits between those two genera und Steno- 

 phragma are not very definite, so I prefer to keep it as an Arabis. 



Sepals påle green with a touch of purple in the tips, petals pure white, filaments 

 faint lilac, anthers white with lilac borders. Ovary lilac brown, style påle green 

 with yellow stigma. No scent. Proterandrous. Stamens all of nearly the same iength;
