Orver XXXIII. UMBELLIFERA. 
Genus 1. Hydrocotyle, Linn. 
1, Hydrocotyle concinna, sp. nov. 
Plant ereeping, slender, pilose, soft, forming dense beds. Stems 2-8 
feet (and more) long, rooting at nodes. Leaves membranaceous, green, 
distant, generally 1, sometimes 2, springing from a node, sub-orbicular, 
8-10 lines diameter, roughish above with glandular pubescence of large 
flattish white and pink hairs, with a few larger and pink coloured ones 
scattered on the veins, deeply 5-lobed, lobes regular, broadest at apices, 
sub-tri-laciniate and sharply toothed, teeth long and curved; petioles 8 
inches long, slender, finely striate ; stipules large, broadly ovate, laciniate. 
Peduneles axillary and lateral (from nodes), erect, slender, much longer 
than the leaves, 4-6 inches long, pink-striped, thickly clothed with weak 
curved hairs; umbels 20-22-flowered; flowers. radiate on long glabrous 
pedicels sub 2 lines long, each bearing a few scattered erect hairs and mostly 
in a single line; involucral leaves and bracteoles numerous, ovate-linear, 
laciniate and pointed; flowers greenish-white tinged with pink, red-striped 
on the outside; petals ovate, obtuse, spreading; calyx tube raised, tubercu- 
late, dark-red ; styles diverging, sub-clavate ; stigmas capitate, red, minutely 
pencilled. Fruit orbicular, at first semi-transparent, echinate, light brown, 
carpels with one rib on each face. 
Hab. In dense rather dry forests, on the ground. Beventy-mile 
Bush, County of Waipawa; 1878-84: W.C. Flowering in March. 
Obs. This is a truely graceful species, neat, pretty, and uniform in all 
its parts. I have long known it, and though I had early considered it to be 
new, and often brought away specimens, I never found time to dissect, 
examine and compare it, until the autumn of 1884, when I did so leisurely 
in its native forests. Sometimes the young immature and unfolded leaves 
present a highly curious appearance ; sessile at the nodes in small globular 
woolly masses, with their green cut and plaited margins fringing their 
tops; reminding one of young hazel-nuts. I believe it to be the work 
of some insect, having found the darkish- yellow larve snugly ensconced 
within. 
2. Hydrocotyle uniflora, sp. nov. "m. 
Stems creeping, rooting at nodes, whence also spring the leaves and 
peduncles fascicled. Leaves glabrous, entire, orbicular-truncate, or oblong- 
orbicular, always truncate at base, 5-7 lines long, rounded at apex, finely 
and regularly crenately toothed (8-4) towards base, and often with one 
small acute tooth at or below the two corners, 5-nerved, green, often purple 
above and covered with very minute white dots as if stippled, margins purple, 
sometimes largely and loosely hairy below at base and on the nerves, veinlets
