306 XXXIV. UMBELLIFEEAE. [Aciphylla. 



pairs, sessile, ovate or ovate-acuminate, sharply toothed or lobed, not piliferous. 

 Stem decumbent, 2in.— 4in. high, simple or with a single branch. Umbels of 

 3—5 unequal spreading rays. Involucre cup-shaped, consisting of 2 broadly- 

 ovate connate apiculate bracts. Umbellules 3— 6-flowered. Pedicels equalling 

 or exceeding the ovate fruits. Carpels with 5 obscure ridges. 



SOUTH Island : on limestone. Trelissick basin, Canterbury, Enys and Kirk. Naseby, 

 Otago, Petrie ! 1,800ft. to 2,500ft. Jan. 



Distinguished from all other species by the entire oup-ehaped involucres. 



20. L. (?) trifoliolatum, Hook. /., Handbk. 97. Small, glabrous. Stem 

 slender, 6in. high, sparingly divided above. Leaves 3-foliolate or pinnate ; 

 leaflets in 1 or 2 distant pairs, Hin. long, on slender petioles, rhombeo-orbicular, 

 cuneate at the base, the rounded tip crenate, glaucous below, reticulate, lower- 

 most sometimes lobed or 3-fid ; petioles slender; sheath short, broad. Umbels 

 small, few-flowered ; rays short or long, unequal, slender. Involucral bracts 

 very short. Flowers white. Styles slender. Fruit unknown.

" A curious little species, at once known by the few petioled leaflets. It is probably 2- pinnate 

 or 2-teruately pinnate. I have only two specimens, and in the absence of fruit am not certain of 

 its genus." 



Not having seen specimens, I have copied this description from the Handbook. The absence 

 of fruit renders it impossible to identify the original plant from description only, but it is most likely 

 identical with the plant described in this work as Oreomyrrhis andicola, Bndl., var. apiculata. 



[A remarkable plant, of which I have very imperfect specimens, has leaves 2-3-pinnate, 

 Sin. -Sin. long and liu.-ljin. broad. The leaflets, 2in.-3in. long, are cut into strict erect apiculate 

 segments, ^in. broad, not coriaceous. As my specimens were collected in the South Island by 

 Dr. Sinclair, I suggest that it should be named L. Sinclairii should better material prove it to be 

 distinct.] 



9. ACIPHYLLA, Forst. 

 Calyx-teeth small, often unequal. Petals incurved, rarely inflexed at the apex. 

 Stylopodia depressed in the male flowers, conical in the female. Fruit oblong 

 or linear-oblong. Carpels sometimes dorsally compressed, each with 5 or 4 

 narrowly-winged ridges or one carpel 3-winged. Vittae 1 beneath each furrow, 

 usually obscure. Erect rigid glabrous perennials. Leaves pinnate or 2— 3-pin- 

 nate, with dagger-like segments and short spines at the apex of the sheath. 

 The rhachis jointed at the insertion of the leaflets. Leaves rarely reduced to a 

 petiole. Umbels compound, usually in the axils of divided spinescent bracteate 

 leaves. Flowers unisexual, forming an elongated dense inflorescence, or rarely 

 paniculate ; the females often with males intermixed. Involucral bracts linear. 



In addition to the New Zealand species, which are endemic and distributed from the East 

 Cape to Stewart Island, two species are found in Australia. The genus is chiefly distinguished from 

 Ligusticum by its coriaceous spinescent leaves and bracts and singular habit. The male inflores- 

 cence of A. Monroi and A. Lyallii, &c., cannot be distinguished from Ligusticum.
