BOTANY OF KERGUELEN ISLAND. 
7. Montia fontana, L. 
Common in wet places. (Marion Island, Moseley, and widely distributed in the 
N. and S. temperate regions). 
8. Acsena affinis, llooh.f Fl. Antarct. 2G8, t. 9G B. 
Common throughout the island. (Marion and the Crozet Islands). 
Called Kerguelen’s tea, and used as a febrifuge by whalers (Kidder). 
Unlike the Frmglea and Cotula, this plant has grown and flowered at Kew 
from roots sent by Moseley. 
9. Callitriche verna, L. ; Suhsp. ohlusangula. C. ohtusangula, Le Gall. ; 
llegelm. Monog. Galt. Callit. 54. C. antarctica, Engelm. ex Regelm. 1. c. ; Kidder in 
Bull. U.S. Nat. Mus., No. 3, 23. C. verna, Ilook.f. Fl. Antarct. 272. 
Common in wet places. (Marion and Heard Islands, Moseley, and widely dis- 
tributed in the K. and S. temperate regions). 
Brom a drawing of the ripe fruit which I made when in Kerguelen in 1840, I 
have no hesitation in referring this to Subspecies ohtusangula, as llegelmeyer did 
from his examination of my dried specimens. The fruit lobes are nearly semi-circular, 
and each pair is united by about two thirds of their faces. The free portions are 
obtusely trigonous at the back. Two forms are common in Kerguelen, as. elsewhere 
in the south temperate zone, one aquatic with long stem and proportionally large 
spathulate leaves, the other smaller, terrestrial, suberect, with obovate or oblong 
leaves ; this flowers the most abundantly. 
10. Tillsea moschata, B. C. Bulliarda moschata, JD’ Urv. 
Abundant in moist places near the sea. (Marion Island, Moseley, Crozets, 
Kidder ; widely spread in high southern latitudes). 
11. Azoreila Selago, ilook.f. Fl. Antarct. 284, t. 99. 
Very abundant throughout the island. (Marion and Heard Islands, IMoseley ; 
Crozets, Kidder ; Buegia ; Mac Quarrie Island.) 
Kidder remarks that the flowers are gi’ecnish yellow, not pale pink as I found 
them to be in winter. Also, that the leaves have not the bristles on the faces of 
the lobes as figured in the Blora Antarctica. I find them on specimens from all 
localities. 
Moseley observes, in reference to this plant at Marion Island, that the mounds it 
forms evidently retain and store up a considerable amount of sun’s heat, and that 
this fact probably explains its peculiar mode and form of growth, and that of many 
otherwise widely different Antarctic plants. He found that a thermometer plunged 
into the heart of a hummock rose to 50°, when the temperature of the air was 45°. 
12. Galium antarcticum, llookf. Fl. Antarct. 303 bis. 
Common, but not found at Christmas Harbour. (Crozets, Kidder ; Buegia and 
Balkland Islands.) 
Kidder remarks that the flowers are distinctly pedicclled, and as often 4- as 3- 
inerous, and even 5-merous ones occur. Eaton’s specimens confirm this.
