CARL SKOTTSBERG, A BOTANICAT. SURVEY OF THE FALKLAND ISLANDS. 



Flower-heads sessile. Involucral scales 



linear-obovate, acutate with obtuse 



apex. 

 Hermaphrodite flowers with nearly cylin- 



drical, slightly widened tube. 

 Appendix V* ^s long as the anther; bran- 



ches of style twice as long as in Ch. 



stolonijera. 

 Beak of achene half as long as the achene 



itself. 

 Pappus white. 



Flower-heads ± pedunculate. Involucral 



scales linear, abruptl}^ truncate, 



obtuse. 

 Hermaphrodite flowers with base of tube 



narrow, thence campanulate. 

 Appendix V2 as long as the anther; bran- 



ches of style half as long as in Ch. 



lycopodioides. 

 Beak of achene as long as or longer 



than the achene iself. 

 Pappus reddish, (colour due to desiccation?) 



I have not seen any specimens of Ch. lanceolata Remy, but to judge from the 

 description it is also closely related to the others, differing in habit and size of the 

 leaves, which are also less densely packed; the heads are pedunculate, the inner in- 

 volucral scales acute. In Herb. Upsal. I have seen a Chevreulia, Lechler 2924, 

 which I hardly can 'distinguish from Ch. lycopodioides ; it is sterile, so I have not 

 been able to settle whether this is endemic in the Falklands or not, Lechler's 

 plant came from the Andes of S. Chile (»terra Pehuenchium»), Spegazzini's »Giia- 

 phalium affine d'Urv. a) pumilum (an O. lycopodioide Gaud.?)» — Pl. per Fueg. coll. 

 p. 63 — has nothing to do with Chevreulia lycopodioides. 



Dry places in the heath, forming dense mats; sometimes ratlier abundant, but 

 easily overlooked and therefore hitherto considered to be rare. E. F., Duperrey 

 Harbour! Darwin Harbour, among grass! W, F., Port Howard! Spring Point! 

 Fox Island! Westpoint Island! slopes on Byron Heights! Saunders Island! Beaver 

 Island! — Endemic? (see above). 



Abrotiinella Cass. 



9. A. emarginata Cass. 



I described and figured the flowers in Feuerl. Bliiten (33), p. 54 — 55. The 

 Falkland plant is slightly different in colour; further, I did not see any pentamerous 

 cT, they were tetramerous like the ?. There are 4 to 8 flowers in the head, 2 to 4 

 of each sex; ^ with påle yellow or nearly white tube, dark lilac brown limb 

 and yellow stamens, ? with påle green tube and lilac brown lobes, base of style 

 yellow, honey-producing (I suppose there most be honey in the cT also, but I have 

 not seen any), iipper V* påle green, stigmse mauve, when fully developed. 



A common cushion-plant, growing on different kinds of soil, in the heath often 

 with Bolax, on quartzite ridges, or in bogs with Ästelia; abundant also on the 

 highest summits! — S. Patagonia, Fuegia, Staten I.
