Flores polygami. Calyx fl. 3 4-partitus, imbricatus; fl. 9 tubus ovario adnatus, limbo 6-fido. Pe- 
tala 0. Stamina calycis laciniis opposita, fl. 3 4, fl. 9 6. Ovarium 6-loculare ; ovulis solitariis, pendulis ; 
stylis 6, divergentibus. Bacca coriaceo-carnosa, 6-locularis; loculis osseis, l-spermis. Semina pendula 
Araliacearum.—Arbores trunco gracili, apice diviso. Folia simplicia (1-foliolata) ; petiolo apice artieulato. 
Flores capitati, involucrati; capitulis paniculatis, polygamo-dioicis. 
One species alone of this fine genus has been found in New Zealand, but I have seen the leaves only; two 
others inhabit Norfolk Island, and a third Tahiti. "They form erect, slender, small trees, with a long simple trunk 
12—20 feet high, and with thick pith, branching sparingly at the top, and bearing very large, coriaceous, entire, 
spreading, simple (unifoliolate) leaves. The flowers are collected into heads, are free or united, unisexual; heads poly- 
gamous and arranged into a stout, sparingly branched, erect panicle. The flowers and fruit are described from 
Norfolk Island species, and may not tally with the New Zealand one. Male flowers :— Cale four-parted. Corolla 0: 
Stamens four, opposite to the calyx. Female :—Calyx tube adnate with the ovary; limb six-parted. Stamens and 
styles six. Ovary six-celled. Fruit with six bony one-seeded nuts.—This genus has been called anomalous by 
Zndlicher on account of its four to six calyx-lobes opposite the same number of stamens, and want of petals, and with 
less reason on account of the simple leaves and unisexual flowers. The structure of the ovary and fruit would be ano- 
malous if, as described by Endlicher, the ovules were erect and seeds margined ; but such is not the case with the Nor- 
folk Island fruits I have examined. Embryo small, with a terete curved radicle pointing to the hilum, and two rather 
broad flat cotyledons. (Name from forpvs, a cluster, and Bevõpov, a tree; from the densely crowded inflorescence.) 
1. Botryodendrum Sinclair, Hook. fil.; foliis longe petiolatis late oblongo-lanceolatis obtusis basi 
cordatis integerrimis. 
Has. Northern Island; between Capes Rodney and Brett, Sinclair. Colenso. 
Leaf coriaceous, shining above, 12-20 inches long, and the petiole nearly as long. There is a tendency to 
become panduriform in the leaf, which contracts above the cordate base; its greatest breadth is 9 inches, the 
general outline obovate or oblong-lanceolate, and the margin is thickened, quite entire, undulated.— Dr. Sinclair 
sends the fruit of Pisonia as belonging to this; the latter has also a very large leaf, but the present exceeds that of 
any other dicotyledonous plant in the Colony. 
Nore. Polyscias pinnata, Forst., introduced into A. Cunningham’s * Prodromus from De Candolle, is errone- 
ously stated to be a native of New Zealand. Forster collected it in the island of: Tanna.

Gen. I. GRISELINIA, Forst. 
Flores dioici. Calya 5-dentatus. Petala 5, valvata (fl. 3 subimbricata). Stamina 5, petalis alterna, 
(in fl. 20). Ovarium (8.3 0) tubo calycis inclusum, 1-2-loculare ; loculis 1-ovulatis; ovulo pendulo ; 
stylis 3, brevissimis, recurvis, intus stigmatosis. Dacca carnosa, 1-2-locularis, 1-sperma, loculo altero vacuo. 
Semen pendulum ; testa membranacea; albumine copioso, dense carnoso; embryone supero, minimo; radi- 
cula brevissima, hilo proxima; cotyledonibus divaricatis.—Frutex lucidus, coriaceus, late virens, radice 
(parasitica?) crassa, tuberosa, Aucubam referens. Folia alterna, integerrima, lucida, obliqua, petiolo caule 
articulato. Flores paniculati, panicula puberula. 
A bright green, lucid, evergreen, leafy, erect, branching shrub, 10-12 feet high, probably parasitical in its young 
state, and afterwards often epiphytical, forming a thick somewhat tuberous root. Leaves alternate, petioled, jointed
