xxyiy Appendix. 



There are two sub-varieties. 



a. Ultimate rays of female umbels sub-racemose, ovaries 



5-celled. 

 h. Ultimate rays of female umbels umbellate, ovaries usually 

 4-celled. 



Tins cl; a: aster, however, is not absolute, as both 4- and 5-celled ovaries 

 may occasioi a'ly be fouud on the same ray. It is, however, certain that in 

 many cases 5-celled ovaries become 4-celled by suppression at a very early 

 sta^e. 



I have seen no ripe fruit so small as the specimen figured by Mr. 

 Buchanan on Plate XXI. 



At Muntaroa I collected specimens of the early leaves of variety /3, 

 which measured 43 ii:ches in length. 



Var. a appears to be local ; I have observed it only in the Auckland 

 district. Mr. Buchanan finds it near Dunedin. 



Var. ft is probably common throughout the colony, except in the Auck- 

 land district, where, I beheve, it has not been observed. Both sub-varieties 

 may be found side-by-sicie about WeUiugton, flowering in February and 

 March. 



A plant common in the Inangahua Valley and other parts of the interior 

 of the South Island is j)robably different from either of the above ; the early 

 leaves, while retaining their elongated form, gradually lose then- teeth and 

 their bronzed hue, assuming the green, glossy texture of the mature leaves, 

 which, in their turn, are more decidedly lanceolate, less serrate, and rather 

 more membranous than in any North Island form. Inflorescence in large 

 compound umbels, only seen in bud. Fruit unknown. 



2. P. ferox, MS. 



p. Zo'H(7iss«?iwm, Buchanan ; Trans. N.Z. lust., IX., p. 530, pi. XX. (Leaf of 

 young plant and male umbel) ; not of Hook. f. 



A small dioecious tree about 20 feet high ; leaves dimoiphic, simple 

 in all stages ; on young plants linear, 12-3 8 inches long, drooping, 

 resembling the early state of P. arisdfuUiini, but much more rigid and 

 coriaceous, irregularly lobulate-dentate, teeth stout, hooked, acute ; mature 

 leaves excessively thick and coriaceous, 8-5 inches long, ^-f of an inch 

 broad, linear obovate, apiculate, gradually narrowed to the base, forming 

 a short petiole ; umbels terminal ; male of 6-10 simple rays, flowers 

 pedicelled, sub-racemose, stamens 4 ; female, compact, of 6-9, 1-3-flowered 

 rays about 1-inch long ; fruit ovoid 5-celled, calycine ring strongly marked, 

 styles 5, connate into a coliimn, tips scarcely recurved. 



Hah. South Island — Near Nelson, Dr. Hector and T. Kirk ; Valley of 

 the BuUer, near the junction of the Matukituki, T.K. ; common near 

 Dunedin, Mr. Buchanan ! (male flowers only).
