iiate, margins cartilaginous ; petioliiles slender, 3 lines long ; 

 stipules large, broad at base, much fimbriate ; petiole (also 

 scape) slender, 2iu.-2^iu. long, pale-green. Peduncles 4-5 

 lines long, stoutish, springing from top of petiole under leaf. 

 Umbels 2-3, in round heads, 20-30-fiowered ; pedicels 1 line 

 long. Involucre many-leaved, leaves long linear, 1-uerved, 

 tips very obtuse, involute. Flowers rather large for plant, 

 showy, dark-purple ; petals sub-obovate ; rhomboid, tips 

 acute; calycine lobes similar in shape, but much smaller. 

 Stamens long, incurved ; .anthers globular. Fruit (immature) 

 slightly ribbed.

Ohs. This is evidently a very pretty and symmetrical little 

 alpine plant, differing much in general appearance h'om the 

 other described species, but possessing aflluiity with P. trifolio- 

 lata, Hook., also with P. microdonta, mihi, here following. I 

 have received four good specimens from its kind discoverer, 

 all very much alike, which (he says) he " got from one plant." 

 To be in keeping with the genus in the " Handbook, Flora 

 N.Z.," I retain Pozoa, though I prefer Azorclla, to which 

 older genus Bentham has removed it. 



2. P. {A.) microdonta, sp. uov. 



Plant perennial, very slender, glabrous; stem 1ft. (or 

 more) long, filiform, prostrate, creeping, purplish, rooting at 

 nodes 2in.-3in. apart ; roots very long, capillary, white. 

 Leaves 2^6 at each node, erect, 3-foliolate ; leaflets equal, 

 distant, divergent at right angles, sub-oblate-orbicular or sub- 

 flabelliform, each 3-4 (sometimes 6-7) lines diameter, 

 margmed, minutely and regularly serrulate under lens ; tips 

 truncate and unequally cut and 5-6 crenate-lobed ; lobes 

 rounded, each mucronate at extremity of vein, 3-nerved, green, 

 membranous, soft, much-veined, with a few scattered white 

 succulent erect hairs on veins of upper surface and at margins ; 

 petiolules l-|-2 lines long; petioles slender, 3in.-5in. long, 

 purple, channelled. Stipules small, with 3-4 rather long and 

 stout succulent ciliiB. Peduncles springing from common 

 petiole, one-third below leaflets, sometimes 2-3 from one 

 point, iin.-liin. long. Umbels (sometimes two unequal 

 umbellules) 2-4- (rarely 6-10-) flowered, their stems stout. 

 Involucral leaves 1-2 lines long, linear-ovate acuminate, 

 lacero-ciliate. Flowers small, shortly pedicelled, Ih lines 

 diameter, calyx a,nd petals forming a regular star; calyx-teeth 

 small, membranous, broadly triangular, abruptly acuminate. 

 Petals distant, spreading, very membranous, narrow sub- 

 rhomboidal, abruptly acuminate, acute, with sometimes a
