of this genus are the leaves entire. The plant has much the same look 

 and habit of growth as Anagosperma, but there are certainly several young 

 seeds in each cell, and it is likely that most of these would mature. Fresh 

 or spirit-preserved specimens are needed to prepare a quite satisfactory 

 analysis of the flowers and fruit. 



10. Atriplex Buchanani T. Kirk var. tenuicaulis var. nov. 



Culmi graciles teretes erecti v. ascendentes parum rigidi a radice longo 

 gracili singuli v. bini v. terni v. quaterni orientes, 12-20 cm. alti, interdum 

 apicem versus + divisi. 



Folia pauca inferne distantia superne crebriora ovato-lanceolata, quam 

 in typo longiora ac angustiora. 



( letera ut in forma typica. 



Stems slender, terete, not stiff, glabrous below, more or less farinose 

 above, springing singly or in twos, threes, or fours from the top of the long 

 slender root, 12-20 cm. high, sometimes sparingly subdivided towards the 

 top. 



Leaves few, distant on the lower part of the stem, closer set above, ovate- 

 lanceolate, subacute or obtuse, usually longer and narrower than in the 

 type. 



Flowers and fruit as in the typical form.

At first sight it is hard to realize that this form can he conspecific with 

 the type, but the differences, which appear to be quite constant, are con- 

 fined to the height, the erect slender habit of growth, and the more scattered 

 leaves, the floral characters showing no important deviation from the type. 

 An examination of fresh or spirit specimens might perhaps show that such 

 differences exist. 



11. Uncinia uncinata (L. f.) Kiikenth. var. pedicellata (Kiikenth.) Petrie 

 var. nov. 



The present variety is Uncinia pedicellata Kiikenth., which 1 am unable 

 to regard as a valid species. It is a widely spread form, marked in the 

 Stewart Island area by a prevalent reddish-brown colouring that is usually 

 absent elsewhere, and is probably attributable to the more or less peatv 

 soil in which it grows there. The rather long stipitate utricles do not 

 differ in any conspicuous way from those of U. uncinata, and the supposed 

 absence in the latter of the annulation at the apex of the nut, on which 

 Kiikenthal lays so much stress in distinguishing the species, has never 

 been observed by me in any specimen I have collected or had access to 

 in the collections of others. The variety is chiefly distinguished by the 

 narrow inflorescence that is frequently longer than in the typical form, 

 the somewhat shorter glumes, and the more decidedly stipitate utricles. 

 The plant has been well known to New Zealand botanical workers for 

 many years, all of whom referred it to U. australis Pers. (= U. uncinata). 

 I have it from the following localities : Kaitaia (Carse !), Tarnaki West, 

 Ruahine Mountains, Hokitika (T. Kirk !), Half-moon Bay, Catlin's River, 

 Chatham Islands (J. S. Tennant !), and Auckland Islands (Aston !).
