CORNACEÆ.
[Corokia.

pedicels short. Petals lanceolate, acute. Drupe ⅓ in. long, broadly oblong, dark-red.—C. buddleoides var. b, Hook. f. Fl. Nov. Zel. i. 98; Handb. N.Z. Fl. 106; F. Muell. Veg. Chath. Is. 16.

Chatham Islands: Dieffenbach, H. H. Travers! Captain G. Mair! Cox! Whakataka; Rokotaka.

Closely allied to C. buddleoides, but amply distinct in the broader leaves, axillary racemose flowers, and larger fruit.


3. C. Cotoneaster, Raoul, Choix, 22, t. 20.—A rigid densely branched shrub 4–8 ft. high; branches tortuous and interlaced; bark black; branchlets, under-surface of leaves, and inflorescence clothed with appressed silvery-white tomencum. Leaves alternate or in alternate fascicles, ⅓–1 in. long; blade orbicular to obovate or oblong-ovate, obtuse or emarginate, coriaceous, shining above, suddenly narrowed into a broad flat petiole. Flowers small, axillary and terminal, solitary or 2⅓4 together; pedicels short, bracteolate. Petals narrow linear-oblong, acute. Drupe globose, ¼ in. diam., red.—Hook. f. Fl. Nov. Zel. i. 98; Handb. N.Z. Fl. 106; Kirk, Students' Fl. 224.

North and South Islands: Not uncommon from the North Cape to Poveaux Strait. Sea-level to 2500 ft. November–January.

What may prove to be a fourth species of Corokia has been collected by myself at Spirits Bay, in the North Cape district. It is a twiggy bush 6–12 ft. high, with slender branches, not tortuous. Leaves alternate, ½–1½ in. long, narrow linear-obovate or oblauceolate, narrowed into very short petioles. Flowers and fruit not seen.


2. GRISELINIA, Forst.

Shrubs or trees; branches terete or angled, transversely scarred at the nodes. Leaves alternate, often unequal at the base, broad, very coriaceous; petiole dilated into a short sheath, jointed on the branch. Flowers small, diœcious, in glabrous or pubescent panicles or racemes; pedicels jointed. Male flowers: Calyx minute, 5-toothed. Petals 5, imbricate. Stamens 5. Disc fleshy, pentagonous. Females: Calyx-tube ovoid or turbinate, limb 5-toothed. Petals valvate or wanting. Rudimentary stamens wanting. Ovary 1–2-celled; styles 3, very short, subulate, recurved; ovules solitary in each cell. Fruit a 1- or rarely 2-celled berry, 1-seeded; seed oblong, testa membranous.

A small genus of 6 species, 4 of which are natives of Chili, the remaining 2 endemic in New Zealand. The Chinese and Japanese genus Aucuba is very closely allied.

Leaves large, 3–7 in., very unequal at the base. Petals wanting in the female flowers 1. G. lucida.
Leaves smaller, 1½–4 in. long, not very unequal at the base. Petals present in both male and female flowers 2. G. littoralis.


1. G. lucida, Forst. Prodr. n. 401.—A stout branching shrub or small tree 3–25 ft. high, often growing on rocks or epiphytic on the branches of tall forest trees; bark thick, furrowed. Leaves 3–7 in.
