I. RANUNCDLACEj®. 
3 
slender climber. Leaves generally biternate, or 3-foliolate with the leaflets 3- 
lobed or 3-partite. Leaflets small, J— J in. long, more membranous than 
in C. fcetida, ovate-cordate, unequally toothed, lobed or almost 3-partite. 
Peduncles and pedicels slender. Flowers small, green, very sweet-scented, 
1-1 Jin. diam., male polyandrous ; hermaphrodite 6-8-androus. Sepals silky. 
Anthers narrow -linear. Achenes glabrous or silky. — C. hexasepala, Lindl. 
Bot. Beg. xxxii. t. 44. 
Var. R. rutafolia, FI. N. Z. i. 7. Leaves biternate or bipinnate, leaflets 5 in. long. 
In various parts of the Northern and Middle Islands. Var. /8, common in the 
Middle Island. Allied to C. hexasepala, from which it is easily distinguished by its smaller 
size and small green flowers; and from fcetida and parviflora, by the broad sepals and 
narrow long anthers : it is certainly not the C. hexapetala of Forster, to which I gave 
the name of C. Colensoi in the New Zealand Flora. 
2. MYOSTJRUS, Linn. 
Small stemless annual herbs, with linear leaves and many 1 -flowered scapes. 
— Sepals 5, gibbous or tubular or spurred at the base. Petals 0 in the N. Z. 
species. Stamens 5 or more. Carpels 1-ovuled. Achenes small, beaked, 
sessile and crowded on the torus, which elongates as they ripen. 
A small genus, native of the temperate northern and southern hemispheres. 
1. M. aristatus, Bentli. ; — FI. N. Z. i. 8. About 1 in. high. Leaves 
2*0 in. broad. Flower minute, greenish, apetalous. Sepals with a spurred 
base. Stamens 5 or 6. Fruiting torus J—J in. long, erect. 
Northern Island : pebbly beach near Cape Palliser, Colenso ; also a native of Cali- 
fornia, and of the Andes of Chili, at 11,500 ft. elevation, but not found in Australia, w'here 
the European (and only other known) species takes its place. 
3. RANUNCULUS, Linn. 
Herbs with petioled radical leaves, and yellow or white flowers. — Sepals 
3-5, concave. Petals 5-20, with 1-3 glands or scales near the base. 
Achenes numerous, small, with short, straight or hooked styles, and one 
ascending ovule. 
A very large genus in all temperate countries, rare in tropical ; mauy are acrid and poi- 
sonous. Some of the N. Z. species are the finest known ; all are very variable indeed.
