Hab. Lord Auckland's group and Campbell's Island ; abundant on wet rocks immediately 

 above high-water mark. 



Petala patentia, obovato-cuneata, concava, albida, ssepe rubro-striata. Filamenta subulata, carnosa, sicci- 

 tate compressa et ut videtur dilatata. Squamie hypogynce 4, carpellis oppositis et iis paulo breviores, cuneata?. 

 Carpetla trigona, obovata, superne oblique truncata, dorso canaliculata : stylis brevibus, recurvis. 



The geographical range of this species is wide, being found along the west coast of South America, from 

 lat. 46° S. to Cape Horn, and also in the Falklands and Kerguelen's Land, but nowhere so abundantly as in 

 this group. Notwithstanding the name given it by its discoverer, I was unable to detect any odour of musk or 

 smell of any kind in the fresh plant. 



XII. UMBELLIFER.E, Juss. 



1. POZOA, Lag. 



Subgen. Schizeilema, Hook.fil. (Involucrum 5-6-phyllum. Flores hermaphroditi. — Herbaceo- 

 carnosa. Caulis repens nodosus.) 



1. Pozoa reniformis, Hook, fil.; foliis longe petiolatis reniformibus multilobatis lobis latis 

 retusis, petiolis basi vaginantibus, pedunculis petiolo brevioribus, involucri foliolis 3-4 linearibus, pe- 

 dicellis 5-7 brevibus, calycis lobis late ovatis obtusis. (Tab. XL) 



Hab. Lord Auckland's group; clefts of rocks and amongst stones on the hills, alt. 1400 feet. 



Herba pusilla, glaberrima, carnosa, facie Hydrocotylis, graveolens. Caulis crassitie penna; passerinse, longe 

 repens, articulatus, nodosus, ad nodos cicatricatus, apice foliosus. Folia A-| unc. lata, exacte reniformia, luride 

 viridia, nitentia, radiatim venosa, lobis late rotundatis. Petioli 2-3 unciales ; vaginis basi magnis latis, superne 

 acutis. Pedunculi ex axillis fohorum, breves, semipollicares. Pedicelli vix 2 lin. longi. Petala parva, obovata, 

 subacuta, medio late uninervia. Stylopodia superne truncata. Fructus oblongus, tetragonus ; mericai-piis de- 

 mum dorso canaliculars. 



A decidedly extra-tropical South American form, belonging to a section of the Nat. Ord. hitherto un- 

 known to the Floras both of New Zealand and Australia. The remarkable similarity of the flower and fruit to 

 those of the P. coriacea, Lag. (Hook. Bot. Misc. vol. i. p. 331. t. 66), together with the uniformity in the struc- 

 ture of its calyx and petals with that plant, have induced me to refer it to the same genus ; but, from the 

 difference in habit and the structure of the involucre of the species thus brought together, I have ventured to 

 place this in a separate subgenus. The original species (P. coriacea), and the P. hydrocotylifolia, Bridges and 

 Fielding (Sertum Plant, t. 40), have the flowers monoecious, a character I do not observe in this. The simila- 

 rity which the present plant bears to the genus Azorella, Gaud., is in many respects close ; the mericarps of this 

 are hardly " parallelim biscutata," whilst those of Azorella are scarcely didymous. Though a very remarkable 

 habit runs through most of the species of the latter genus, one of them, the A. Ranunculus, D'Urv., not only 

 differs from its congeners in form and mode of growth, but in these respects much resembles this plant. In the
