4. H. spicata, Petrie in Trans. N.Z. Inst. xix. (1887) 325.— 
A slender erect or ascending sparingly branched herb 4—10in. 
high, glabrous or pubescent. Leaves few, opposite, shortly pe- 
tioled, 4-2 in. long, ovate or elliptic-ovate, acute or subacute, coria- 
ceous, serrate, pubescent. Flowers in slender terminal branched 
panicles, sessile in the axils of minute opposite or alternate bracts ; 
terminal 1-3 flowers female; lower flowers apparently all male, 
but many of the bracts empty in my specimens. Calyx-lobes 4, 
triangular. Anthers 4; filaments short. Stigmas plumose. Fruit 
75 in. long, 4-angled; interspaces smooth or slightly wrinkled.—

SourH Isnanp: Otago—North end of Lake Hawea, altitude 1100 ft., 
Petrie ! 
A very curious plant, agreeing with H. depressa in the leaves and fruit, but 
differing widely in the paniculate inflorescence. I suspect that it will prove to 
be an abnormal state of H. depressa. 
5. H. micrantha, &. Br. ex Sieb. and Zucc. Fl. Jap. i. 25.— 
A tufted much-branched procumbent or ascending herb 2-6 in. 
high; stems and branches slender, wiry, glabrous or slightly 
scaberulous. Leaves opposite, very shortly petioled, 1+in. diam., 
broadly ovate or almost orbicular, obtuse or subacute, coriaceous, 
crenate-serrate, the crenatures broad and rounded. Flowers 
minute, drooping, in slender almost filiform racemes terminating 
the branchlets ; pedicels very short. Petals 4, more than twice as 
long as the triangular calyx-lobes. Fruit j,in. long, broadly ob- 
long, 8-costate, interspaces smooth and shining.—Hook. f. Handb.
