Pktrie. — New Species and Varieties of Native Phanerogams . 271 



Flowers rather few, in bracteate umbels terminating the main axis and 

 the lateral peduncles (12 cm. long or less), ultimate pedicels 4-5 mm. long. 



Calyx about 1 cm. long, cut for three-fourths its length into 4 linear- 

 aubulate 1 -nerved lobes. 



Corolla (in the specimens examined not fully expanded) white, some- 

 what longer than the calyx, deeply divided into 5 acute lobes. 



Stamens half as long as the stout pistil. 



Hab.—Ljell Creek, 1,000 ft., and Boundary Peak, near edge of scrub 

 (south-west Nelson), 4,000 ft. 



Mr. William Townson has kindly lent me his specimens of this plant, 

 which he collected in the two localities mentioned above. He did not 

 succeed in finding plants with the flowers expanded, but the stamens in the 

 partially closed corolla have already shed their pollen. The leaves are 

 unusually large and thin, and the intervals between the cauline leaves 

 remarkably long. I have what may be the same plant from Mount Blairich, 

 collected by the late Henry J. Matthews, but the specimens are too im- 

 mature to warrant a decided opinion. 



10. Convolvulus fracto-saxosa sp. nov. 



Perennis, ubique pubescentia cinerea copiose vestita. 



Rhizoma gracile radices tenues ramosos subhorizontales edens. 



Caules simplices v. a basi divisi, procumbentes. 



Folia longe petiolata, trimorpha, forma ac magnitudine variabilia ; 

 in forma ultima ac simul multo frequentissima laminae longae (ad 3 cm.), 

 angustae, subhastate tripartita, lobo terminal! lineari obtuso v. subacuto 

 supra + canaliculato (costa obscura), lobis lateralibus a laminae basi 

 emissis subtriangularibus a parte exteriore dilatatis ac plerumque alte 

 divisis. 



Flores axillares, solitarii, longe pedunculati. 



Sepala inaequalia, late obovata, + crenata. 



Corolla alba, 2 cm. in diam. 



Perennial, everywhere densely clothed with copious rather long slate- 

 grey pubescence. 



Rootstock rather slander, fleshy, sending off thin branching nearly 

 horizontal roots. 



Stems slender, simple or branched from the base, prostrate or trailing, 

 leafy, 8-16 cm. long. 



Leaves petiolate, thin, trimorphic, variable in size and shape ; primary 

 (earliest) shortly petiolate with small semicircular or broadly ovate or 

 ovate-cordate entire or sinuate blades about | cm. long and 1 cm. broad : 

 intermediate with longer petioles and blades 1^ cm. long, f cm. broad, 

 divided into 3 oblong obtuse entire or slightly sinuate lobes (the terminal 

 lobe at right angles to and longer than the two lateral lobes) ; the ordinary 

 form on longer petioles (3-4| cm.) with subhastately tripartite blades 

 2-3 cm. long and 1-lf cm. broad (at the base), the terminal division long 

 narrow obtuse or subacute, more or less chanelled above, with obscure mid- 

 rib, the basal divisions subtriangular narrow at the point of origin and 

 widening outwards, sometimes entire, but usually deeply cut in front into 

 2 widely diverging subacute lobes. 



Flowers axillary, solitary ; peduncles as long as the petioles, thickened 

 above and with 2 linear short brarts a little wav below the flower.
