Solitary plants rising above this carpet: 



Accena ludda Senecio candicans Oreomyrrliis andicola. 



Aiiium australc » vulgaris 



Of these, Ranunculus acaulis is especially noticeable. We found it in a second 

 place, opposite Westpoint Island, where the sand was also rich in calcareous particles. 



Bryophytes: Bryum heteroblepharum Card. n. sp., miserum, Tortula antarctica, 

 robustvla. 



27. Loose, crumbling sandstone, giving rise to a sandy clay, which is easily 

 washed away by riinning water; slips also occur in such places. Port Philomel, 

 W. F. — ^cöB?ia-association. 



Spårs. Acmia lucirla Spårs. VioJd maculata Sol. Accena adscenäens. 



Of these, A. lucidu is especially characteristic of such localities, described by 

 me before from Duperrey Harbour, Its long, tough rhizomes enable it to endure 

 the pressure of the loose clay, On a similar steep wall of fine clay in Westpoint 

 Island, we noted Bryum argenteum, pseudogemmatum Card. n. sp., OrtJiodontium 

 australe, Webera leptoclada Card. n. sp. 



28. More or less shifting sand, Port Harriet, E. F. (Pl. XI: 3.) 



• Port Harriet is a good place for a study of Falkland sand-plants. All along 

 the harbour the beach is formed of sand, here and there with small dimes, The 

 heath near the coast is very sandy, and in several places the drift-sand was gaining 

 ground; the soil had been broken up, the remains of the heath formed small, isolated 

 hillocks, between which the pure sand lay bare and barren; the wind had eroded deep 

 and broad channels between the hillocks. These were inhabited by Pernettya pumila, 

 Empetrum rubrutn and Baccharis magellanica. Both Empetrum and Pernettya had 

 suffered much and had been partly killed by the sand. Some dusters of Perezia 

 recurvata and, less frequently, N nssauvia Gaudicliaudii were seen. Mosses were rare : 

 Brachythecium austrosalebrosum, Bryum sabuletorum Card. n. sp., Distichium capilla- 

 ceum, Tortula rubra. 



Of cushion-plants there were Bolax gummifera with Abrotanella emarginata, and 

 a remarkable form of AzoreUa jilaynentosa which I call f. marithna. The wind had 

 swept away the sand round the cushions, which had been left on pedestals and still 

 seemed to be doing tolerably well. The sand between the hummocks was covered 

 with a Juncus scheuchzerioides-a.ssoGi?ition. 



Near the shore the quartzite peeped out of the sand. Here I noted 



Spårs. Agropijrmn magellanicum Sol. Atropi!< PresUi Festuca arenaria 



Apium australe Crassula moschata G-alium antareticum. 



Deschampsia flexuosa 



Outside this, down towards the tidal region, was the typical vegetation on 

 shifting sand in the littoral zone, the Senecio candicans-associsbtion (Pl. XI: 4), 

 easily recognised from the large leaves of Senecio with their dense, white wool.
