appendage within which arises from the base of the carpel and 
partly surrounds the seed. Seed pendulous or horizontal.

in New Zealand. 
1. G. Lyallii, J. H. Baker in Journ. Bot. xxx. (1892) 137.—A 
small graceful spreading tree 15-30 ft. in height; young branches, 
leaves, petioles, and inflorescence more or less covered with stellate 
pubescence. Leaves on slender petioles 1—2in. long; blade 2—4in., 
ovate, acuminate, usually deeply doubly crenate, sometimes shortly 
lobed and crenate, cordate and truncate at the base, membranous. 
Flowers abundantly produced, large, #-lin. diam., white, in axil- 
lary fascicles of 3-5, rarely solitary; peduncles slender, 1—2in., 
ebracteolate. Calyx broadly campanulate, 5-lobed ; lobes triangu- 
lar. Petals obliquely obovate, retuse towards the apex. Staminal 
column short, swollen at the base; filaments numerous, long, fili- 
form. Ovary 10-15-celled; styles long, slender, filiform, free to 
below the middle; stiginas obliquely capitate. Fruit 4in. diam., 
globose, slightly depressed, of about 12 much-flattened membranous 
reniform carpels. Carpels not winged, 2-valved, 1-seeded. Seed 
much compressed.—Kirk, Students’ Fl. 72. Hoheria Lyallu, Hook.

SourH IsuAnp: Subalpine forests from Nelson to Otago, most plentiful on 
the western side. Ascends to 3500 ft. Lacebark. December—January. 
One of the most beautiful trees of the New Zealand flora, often forming a 
broad fringe to the subalpine beech forests. It is partly deciduous at high eleva- 
tions, but is certainly evergreen in the river-valleys of Westland and Nelson, 
where it is very abundant. There are apparently two forms of flowers, one with 
long styles almost equalling the stamens, another with styles less than half 
their length. 
4. HIBISCUS, Linn. 
Herbs, shrubs, or trees; glabrous, tomentose, or hispid, the hairs 
usually stellate. Leaves very various, often more or less palmately 
lobed. Flowers large and showy. Bracteoles numerous, rarely few, 
usually narrow, free or connate at the base. Calyx 5-toothed or 5- 
fid, valvate. Petals 5, adnate at the base to the staminal column. 
Staminal column truncate or 5-toothed at the summit; filaments 
many, inserted on the sides of the column; anthers reniform. 
Ovary 5-celled; ovules 3 or more in each cell; styles 5, spreading ; 
stigmas capitate. Capsule loculicidaily 5-valved. Seeds glabrous 
hairy or woolly. 
A large and beautiful genus, abundant in the tropical regions of both hemi- 
spheres, a few species only extending into the north or south temperate zones. 
Both the New Zealand species have a wide distribution outside the colony.
