 H. uniflora, T. Kirk in Trans. N.Z.I, ix. (1876) 540, is a form with solitary terminal flowers, which 

 sometimes prevails over wide areas. 



NORTH and SOUTH Islands : Three Kings Islands and the North Gape to STEWART Island. 

 Ascends to 3,500ft. 



Best distinguished from H. Utragyna by the opposite floral leaves and the smooth interspaces 

 of the fruit. 



4. H. spicata, Petrie in Trans. N.Z.I, xix. (1885) 325. Stems sub- 

 erect or ascending, 4in.-10in. high, pubescent or silky. Leaves opposite, very 

 shortly petioled, subcoriaceous, ovate or oblong-lanceolate, acute or subacute, 

 serrate, pubescent. Flowers in terminal slender-branched panicles, sessile in 

 the axils of minute alternate or opposite bracts, the terminal flower or sometimes 

 the two highest flowers female, the lower bracts flowerless or with a minute 

 male flower. Anthers 4 ; filaments very short. Fruit about ^^in. long, 

 4- angled ; interspaces smooth. 



SOUTH Island : terraces, north end of Lake Hawea, 1,150ft., Petrie. 



Although the particulate inflorescence differs widely from that of any other New Zealand 

 species, I have no doubt that this plant is an aberrant form of H. depressa, with which its leaves and 

 fruits exactly agree. All the specimens dissected by me have 1-celled seedless fruits — a peculiarity 

 very common in single-flowered specimens of H. depressa. Its appearance, however, is so very 

 singular that for the present it seems worth while to allow it specific rank. 



5. H. micrantha, R. Br. ex Sieb. and Zucc. Fl. Jap. Nat. i. 25. A 



small tufted species, with filiform stems and branches lin.— 6in. long, glabrous 



or rarely scaberulous, diffuse or ascending. Leaves all opposite, very shortly 



petioled or sessile, orbicular-cordate or ovate, rarely more than Jin. in diameter, 



crenate or obscurely crenate. Flowers few, in short terminal leafless racemes. 



Pedicels very short. Petals 4. Styles and ovules 4. Fruit pendulous, 8-ribbed ; 



interspaces smooth. — Hook, f., Fl. Tasm. i. 121 ; Handbk. 66 ; Benth., PI.

NORTH and SOUTH Islands : from the North Cape to the Blufi ; STEWART Island. Sea- 

 level to 2,300ft. Nov. to Jan. Also in Australia, eastern Himalaya, Bengal, and Japan. 



2. MYRIOPHYLLUM, Linn. 

 Flowers unisexual or hermaphrodite. Calyx-tube very short or in the 

 male flower, 4-toothed or lobed ; petals 4, imbricate ; stamens 4—8, filaments 

 short. Female : calyx-tube ovoid, lobes minute or ; petals ; ovary 2- or 

 4-celled ; ovules 1 in each cell, pendulous ; styles 2 or 4, often plumose. Fruit 

 2— 4-celled, furrowed between the carpels, ultimately dividing into 2 — 1 hard
