BOTANY. 23 



2. MoNTiA FONTANA, L. — Flowers were first observed December 7. 

 Habitat among gravel, near the sea, and (as remarked by Dr. Hooker) 

 almost always very near CalUtriche verna and Ranunculus crassipes. 



v.— ROSACEA]:. 



1. AC^NA AFFINIS, HooTc. j^?.— " Kergueleu Tea." The leaves have 

 a considerable reputation among the whalers as a febrifuge and anti- 

 scorbutic. They are used as an infusion, hence the trivial name. 

 Abundant everywhere, especially on northeast hill-sides near the sea 

 and in low land. In the flowering state, the specimens accord well with 

 the A. adscendens, as described and figured by Dr. Hooker; but in fruit 

 the characters relied upon to distinguish the two become quite apparent. 



VI.— HALOEAGEiE. 



1. Callitriche Antarctica, Engelm. in Hegel MS. Syst. Callitr. {G. 

 Verna, HooTc. fil, Fl. An^arc.).— Grows in wet places, generally in 

 company with Ranunculus crassipes, often under water or beneath precip- 

 itous rocks overhanging and limiting rocky sea-beaches. Flowers first 

 observed December 17. Montia fontana is generally to be found near at 



hand. 



VII.— CRASSULACE^. 



1. BuLLiARDA MOSCHATA, D'CTrv.- Small, white, perfect, regular, 

 tetramerous flowers, first observed in bloom December 18. Pistils and 

 stems blood-red. Plentiful in crevices of rocks overhanging and closely 

 neighboring to the sea. 



VIII.— UMBELLIFER^. 



1. AzoRELLA SELAGO, Eooli. fil— One of the commonest plants, 

 growfng in mounds closely compacted together, often 2 to 4 feet in 

 diameter, and composed of the dead stalks of old plants. Owing to the 

 density of this crowding, only the surface is green, while deeply in the 

 interior the old stems and leaves seem to be partly transformed into 

 peat. It is this plant which makes walking so fatiguing on this island. 

 The foot sinks into the soft mass at every step, and the hillocks are so 

 closely joined together that for long distances it is impossible to avoid 

 them. I could not find the hairs or bristles figured and described by 

 Dr. Hooker as appearing ui^on the upper surfaces of the leaves along 

 their venation {Fl Ant. p. 284). Flowers were first observed November 

 12, like small starry points, scattered over the mounds. They are never 

 very conspicuous, and do not press well, owing to the strength and
