l. Hanunculus tenuicaulis, n. sp. 
Very slender, sparingly pilose or nearly glabrous, 6-18 inches high. 
Rootstock long, rather stout, sending down numerous fleshy fibres. Leaves 
few (1-4), all radical, very variable in size and cutting, about reniform in 
outline, cut to the base into 3 (rarely 5) broadly cuneate divisions, which 
are deeply and irregularly 2-8-lobed ; lobes narrow, often again toothed ; 
texture thin, herbaceous ; petioles very slender, variable in length, 1-4 
inches. Scape slender, grooved, one-flowered, usually with three variously 
cut or lobed bracts about the middle. Petals not seen. Achenes 8-20, 
loosely packed and spreading on all sides, i inch long, shortly stipitate, 
somewhat fusiform, gradually narrowed upwards into a long spirally re- 
curved style. | 
Hab. Canterbury mountains above Arthur’s Pass, altitude 4,000- 
5,000 feet. T.F.C, 
A very distinct and well-marked plant. In habit and appearance it is 
perhaps nearest to H. geraniifolius, but it differs from that plant, and from 
all the other New Zealand species, in the stipitate and fusiform achenes, 
with spirally recurved styles. 
2. Myosotis (Exarrhena) concinna, n. sp. 
Àn erect or diffuse perennial, 6-18 inches high, branched from the base, 
covered in all its parts with fine closely-appressed silky hairs. Flowering 
stems or branches numerous, rather stout, leafy. Radical leaves usually 
many, 2-4 inches long, from linear- or lanceolate-spathulate to narrow 
oblong-spathulate, aeute or obtuse, gradually narrowed into long petioles, 
covered on both surfaces with fine closely-appressed silky hairs.  Cauline 
leaves sessile, lanceolate or oblong-lanceolate, acute. Racemes large, simple 
or branched, usually forming a rather dense many-flowered head, rarely 
elongated. Flowers large, bright pale yellow, sweet-scented, shortly pedi- 
celled. Calyx 4 inch long, 5-partite, lobes covered with appressed silky 
hairs. Corolla broadly funnel-shaped or almost campanulate, 4 inch long;  . 
tube very short, limb large, deeply lobed, lobes oblong or ovate, acute or 
obtuse. Filaments very slender, elongate; anthers linear-oblong, exserted 
far beyond the corolla. Nuts ovoid, red-brown, but not seen perfectly 
ripe. i an 
Hab. Nelson, abundant on the débris of limestone rocks on Mount 
Owen, altitude 3,500-4,500 feet; also on Mount Arthur, altitude 4,000 feet.
