1. Ranunculus Grahami sp. nov. 



Folia radicalia pauca, coriacea, + 10 cm. longa ; petiolis 6-7 cm. longis r 

 crassiusculis, subcomplanatis, inferne vaginantibus ; laminis semi-orbicu- 

 laribus, 5 cm. latis, in segmenta tria late cuneata partitis, segmentis in 

 lobos 3-5 breves rotundatos sectis. Folia oaulina 1-2, subdistantia, radi- 

 calibus similia sed minora breviusque petiolata. 



Scapi foliis longiores, petiolis graciliores, in fructu + 15 cm. longi, glabri, 

 1-flores (1-4-flores ?). 



Flores majusculi, + H cm - l*** I sepala 5, obtusa, plurinervata, extra 

 parce subpilosa ; petala 10, sepalis longiora, l|cm. longa, anguste cuneata, 

 obtusa ; stamina 1-2-seriata ; carpella plurima ; achenia turgida, breviter 

 2-alata, rostro longo curvato. 



Rootstock rather stout, descending, giving off numerous fleshy lateral 

 roots. 



Radical leaves few, coriaceous, + 10 cm. long ; petioles 6-7 cm. long, 

 rather stout, glabrous, more or less flattened and expanded below into a 

 broad sheath bearing sparse silky hairs at its mouth ; blades semiorbicular 

 in outline, broader than long, deeply parted into 3 broadly cuneate segments 

 that are cut into 3-5 short rounded lobes, glabrous but for a few delicate 

 silky hairs on the margin and upper part of the back, nerves obscure, reticu- 

 late, veining evident. Cauline leaves 1-2, rather distant, similar to the 

 radical, but smaller and with shorter petioles. 



Scapes more slender than the petioles, exceeding the leaves, in fruit 

 + 15 cm. long, glabrous, 1 -flowered (in my specimens). 



Flowers rather large, + \\ cm. across. Sepals 5, broadly ovate, obtuse, 

 membranous, yellowish, many-nerved, sparsely covered outside with delicate 

 white silky hairs ; petals 10, longer than the sepals, 1| cm. long, narrow- 

 cuneate, obtuse, yellow, bearing a single nectary near the base ; stamens 

 in 1 or 2 series, with rather long flattened filaments ; carpels very 

 numerous ; achenes turgid, shortly 2-winged with a long curved beak and 

 a few delicate silky hairs chiefly on the wings. 



Hob.— Rocks of " Aiguille Roque," a peak south of Malte Brun, Mount 

 Cook district, 9,000 ft. ; Coronet Peak, Mount Cook district. 



Mr. Peter Graham, chief guide at the Hermitage, collected this plant, 

 which is named in his honour. He writes me that the scapes frequently 

 bear 3 or 4 flowers. The plant seems more nearly related to R. pinguis 

 Hook. f. than to any of the mainland species. 



2. Epilobium antipodum sp. nov. 



Epilobium E. confertifolio Hook. f. afline ; differt foliis majoribus, 

 elliptico-obovatis, in petiolos latiusculos paene aequilongos attenuatis, cap- 

 sulis robustioribus longioribusque.
