South Island : Otago — Mount Alta, /. Buchanan and 

 McKay; 5,000ft. 



A remarkable species, allied to V. tetrasticha, Hook, f., but 

 distinguished by its erect wiry branches, smaller leaves, and 

 umbellate flowers. I am indebted to my friend Mr. Buchanan 

 for a small portion of his original specimen, but more copious 

 material both of this and of V. uniflora must be obtained 

 before a satisfactory diagnosis can be drawn. The leaves of 

 this plant are more minute than those of any other New Zea- 

 land species. 



V. uniflora. 



A rigid much-branched plant, 2in.-4in. high, with nume- 

 rous short tetragonous branches iin.-liin. long, about ^in. 

 diameter. Leaves densely imbricating, 4-farious, connate at 

 the base, ovate, concave, ciliate near the base. Flowers 

 solitary, terminal. Calyx deeply divided, lobes 5. Stamens 

 2, filaments very short, included. Ovary villous above. Cap- 

 sule not seen. Logania armstrongii, J. Buchanan, in Trans. 

 N.Z. Inst., xiv. (1881), 347, t. xxvhi., f. 3. 



South Island : Otago — Hector's Col, Mount Aspiring, 

 Biiclianan and McKay ! 5,000ft. 



My knowledge of this curious little plant is confined to 

 Mr. Buchanan's original specimen, which he kindly allowed 

 me to examine. Ic is allied to V. tcstrasticha, Hook, f., aiid 

 V. lycoyodioides, Hook, f., but differs from both in the 

 solitary terminal flowers and the 5-lobed corolla. 



V. lycopodioidcs, Hook, f., Handbk., 211. 



An erect much-branched spreading shrub, lft.-2^ft. high. 

 Leaves of young state filiform, simple or pectinate, or ovate or 

 oblong, lobed or pinnatifid. 



South Island : Alpine districts in Marlborough, Nelson, 

 Westland, Canterbury, and Otago; 2,500ft.-6,000ft. 



V. tetragona, Hook, Ic. PL, t. 580. 



Procumbent or erect, 6in.-30in. high. Leaves in the 

 young state linear-subulate with a broad base, entire, obtuse, 

 laxly imbricating. Sepals and bracts furrowed longitudi- 

 nally. Capsule broadly oblong, exceeding the sepals, sub- 

 acute, slightly compressed. 



North Island : In mountain districts, Hikurangi, East 

 Cape, Kaimanawa Eange, Ruahine Eange, Tongariro, Ngau- 

 ruhoe, Ruapehu, &c., Tararua Eange to Mitre Peak and 

 Mount Holdsworth, in great abundance. South Island :
