1. Ranunculus Baughani S|). no v. 



Pla'jta tota pilis flavido-albidis appressis molliter villosa. 



Folia radical ia pauca (?), petiolata, 4-5 cm. Jonga ; petiolus crassius- 

 culus, + 2 cm. longus ; lamina late ovato-doltoidea, 2 cm. loaga, 2| cm. 

 lata, tripinnatisecta ; segmenta ultima brevia, angusta, acuta v. sub- 

 acuta ; caulina pauca. congesta, bracteis similia, subsessilia, radicalibus 

 minora minusque secta. 



Scapus crassitudine mediocri, circa 8 cm. altus, apicem versus ad tres 

 ramos 1-floriferos edens. 



Flores breviter pedicellati, 1|— 2 cm. in diam., laete flavi. 



Sepala 5, petalis fere aequilonga, lata, obtusa, tenuia, pallida, pluri- 

 nervata, extra parce villosa. 



Petala 10, apice rotundata, basim versus cuneato-angustata, pluri- 

 nervata. 



Stamina et pistilla plurima. 



Acbenia matura baud visa. 



The whole plant villous with soft yellowish-white appressed hairs. 



Kadical leaves appa,rently few, petiolate, 4-5 cm. long ; petiole rather 

 stout, + 2 cm. long ; blade broadly ovate-deltoid, 2 cm. long, 2| cm. broad, 

 trifoliolately divided, the primary divisions once or twice piunatisect ; 

 ultimate segments short, narrow, acute or subacute. 



Cauline leaves few, bract-like, sessile or nearly so, approximate, smaller 

 and less divided than the radical. 



Scape moderately stout, about 8 cm. high, divided near the top into 

 3 or fewer branches, each bearing a single flower. 



Flowers peduncled, 1^2 cm. across, large for the size of the plant. 



Sepals nearly as long as the petals, broad, obtuse, thin, pale, many- 

 nerved, sparsely villous on the outside. 



Petals 10, bright yellow, rounded at the top and cuneately narrowed 

 to the base, many-nerved ; nectaries basal (apparently 3). 



Stamens and pistils very numerous. 



Ripe achenes not seen. 



^a6.— Mount Balloon (Te Anau - Milford Track). 



This species is named in honour of Miss B. E. Baughan, by whom it 

 was collected as above. The material for its description, which was very 

 scanty, was lent me by Mr. R. M. Laing, B.Sc, of Christchurch. The 

 plant has its nearest ally in R. sericophyllus Hook, f., in which, however, 

 the scapes are always 1-flowered. 



2. Epilobium rostratum Cheesui. var. pubens var. nov. 



Planta typo humilior magisque diffusa, caulibus foliis capsulisque valde 

 pubescentibus. 



More depressed and spreading than the type, with the stems, leaves, 

 And capsules strongly pubescent.
