USS. C. dissita 8, Solander, MSS. C. viridissima, 802. (juvenilis). 
Has. Northern Island; in woods, etc., frequent, Banks and Solander, Sinclair, ete. 
A very similar species to C. dissita, indistinguishable from it in general appearance, but the perigynia are only 
toothed at the mouth, not divided into two prongs, like a fork, as in that species. 
21. Carex vacillans, Sol.; spicis 5-9 cylindricis cinnamomeis, & 1-4, reliquis ima basi masculis 
infima remota (seepe radicali) vel inferioribus longe exserte pedunculatis nutantibus basi attenuatis laxifloris 
simplicibus compositisve, perigyniis fusiformibus triquetris bifidis nervosis deciduis squama lanceolata 
hispido-aristata longioribus, stigmatibus 3. Boott, MSS. 
Has. Northern Island; common in moist woods, Banks and Solander, ete. 
A more rigid, harsh species than C. dissita or C. Lambertiana, with smooth, nerved leaves. Culms 13-21 feet 
high, slender, shorter than the leaves, which are three lines broad. Spikes five to nine, pale brown, slender, on long 
slender peduncles, the lower drooping, 1-21 inches long, + inch diameter. Scales and perigynia deciduous, loosely 
imbricated, the former lanceolate, narrowed into a long hispid awn; the latter spindle-shaped, bifid, and strongly 
nerved. Bracts long and leafy. : 
22. Carex Forsteri, Wahl.; spicis 5-8 pallidis eylindrieis, 2 1-3 gracilibus, reliquis (v. omnibus) 
basi masculis, superioribus (apice sterilibus) approximatis sessilibus, inferioribus remotis exserte pedunculatis 
demum pendulis longissime bracteatis, infima rarius composita, perigyniis ovato-lanceolatis bifidis nervosis

C. recurva, Schkuhr, Car. n. 84. C. punctulata, 4. Rich. Flor. t. 22. 
Has. Northern and Middle Islands; abundant in moist woods, Banks and Solander, etc. 
A very handsome, tall Sedge, 2—4 feet high, resembling 0. fascicularis in habit and general appearance, differing 
in wanting the terminal male spike, very variable in the size of all its parts, of a pale colour. Leaves 1-1 inch 
broad, with three strong nerves, much longer than the culms. Spikes 11-3 inches long, pale yellow-brown, 
suberect, nodding or drooping, squarrose from the diverging or recurved, ovate lanceolate, bifid, pale perigynia, 
which are as long as the cuspidate scales, and become dotted in age. Bracts long, broad, and leafy. 
Os. The C. appressa, Br., of Lord Auckland's Group, is erroneously stated (Fl. Antarct. p. 91) to be a native 
of New Zealand. It much resembles C. virgata, but is a more robust, broader-leaved plant; and being found in 
Tasmania also, it will, in all probability, be found in the southern parts of New Zealand. 
Gen. XVI. UNCINIA, Pers. (Auctore Francisco Boott, M.D.) 
Omnia Caricis, sed perigynium fl. fem. seta hypogyna exserta apice hamata auctum. 
A remarkable genus, containing about thirty species, most of which are natives of damp climates in south 
temperate latitudes, as Australia, New Zealand, Chile, ete. A few are found in Tropical America. The genus 
differs from Carex only in the curious flat appendage to the female flower: this is inserted below the ovary, pro- 
jects beyond the perigynium, and is hooked at the tip; its exact nature is obscure, but it probably represents a 
continuation of the axis of the flower. (Name from oyxuvos, a small hook.) 
§ a. Perigynia scabrous. 
1. Uncinia scabra, Boott; spica filiformi laxiflora subelongata nuda v. bracteata, perigyniis lanceolatis 
dorso leviter nervatis apice scabris margine serratis squama lanceolata acuta v. obtusiuscula persistente 
longioribus. Boott, MSS.
