36 BOTANICAL RESULTS OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 



In conclusion, I have to thank the authorities at Kew and the British Museum for 

 the facilities granted me for working in their herbaria ; and Dr 0. V. Darbishire and 

 Mr C. H. Wright for their respective shares in this paper. To the late Mr C. B. 

 Clarke I am particularly indebted for his determination of the species of Scirpus ; and 

 I would express my thanks to Mr A. N. Bruce, B.Sc., for the care and trouble he has 

 taken in the drawing of the plate of Cotula goughensis.

DlCOTYLEDONES. 



PHYLIGA NITIDA, Lam. Encycl., ii. p. 77 ; D. C. Prodr., ii. p. 35 ; Hemsl. Chall. Bot., 

 i. ii. p. 148, t. 25. P. arborea, Thou. Esq. Fl. Trist., p. 45. P. mauritiana, Bj. ex 

 Baker, Fl. Maurit., p. 53. 



Very common on the island up to a height of about 2000 feet, growing even on 

 the most exposed ridges. It seldom grows more than some 25 feet in height, 

 and the stems are always much bent and gnarled and generally covered with a 

 growth of lichens. 



Distribution. Tristan da Cunha, Inaccessible and Nightingale Islands, Amsterdam 

 Island, Reunion and Mauritius. 



HYDROCOTYLE LEUCOCEPHALA, Cham, et Schlecht. in Linnsea, i. (1826), p. 364. 



Common in the glen in swampy places under waterfalls. This species differs 

 from Hydrocotyle capitata, Thouars the Tristan da Cunha plant in the almost total 

 absence of hairs on the leaves and leaf-stalks, except an occasional sparse covering 

 near the blade. 



Distribution. Brazil and Paraguay. This species does not appear to have been 

 recorded outside these two countries. 



APIUM AUSTRALE, Thou. Esq. Fl. Trist., p. 43 ; Hook.f. Handb. Fl. N. Zeal., p. 90 ; 

 Hemsl. Chall. Bot., i. n. p. 149. 



Common on the low-lying ground down to high-water mark and growing very rankly 

 in places. It appears to be a very variable plant, and the Gough Island variety has 

 the leaves broadly ovate, and not linear like the specimens from Tristan da Cunha of 

 Carmichael and Moseley. 



Distribution. Tristan da Cunha and Inaccessible Island, and very generally in 

 extra-tropical regions of the southern hemisphere. 



NERTERA DEPRESSA, Gaertn. Fruct., i. p. 124, t. 26 ; Hook. f. Handb. Fl. N. Zeal., 

 p. 120; Hemsl. Chall. Bot., i. n. p. 150. 



Erythrodauum alsineforme, Thou. Esq. Fl. Trist., p. 42, t. 10 (Nertera). 

 Common in the drier and more barren places.
