Kirk. — On the Lake District of the North Island. 345 



G. oppositifolia, Hook. f. — Attains its northern boundary at Kotukuroa 

 creek, but cannot be compai-ed in luxuriance with the splendid specimens 

 at Kotokakahi and Lake Taupo ; ascends to 3,200 feet on Tarawera 

 mountain. 



Cyathodes empetrifolia, Hook. f. — Attains its northern limit in a fissure in the 

 Waihorepa valley, and on Tarawera mountain. In the valley the stems 

 are diffuse, 2 to 6 feet long ; on the mountain short and erect. 



Dracophyllum strictum, Hook, f. — The common form in the district is var. 6., 

 but the two forms pass insensibly into each other, h. occurs in the 

 summit of Tarawera mountain, and reaches its northern limit at the 

 Tamahere narrows. Middle Waikato ; a most attractive plant. 



D. longifoliwni, Br. — Attains its northern limit on the summit of Tarawera, 

 altitude, 3,600 feet. Identified in the absence of flowers, but the habit 

 of the plant can scarcely be mistaken. 



D. suhulatum, Hook. f. — The most characteristic plant of the Taupo district, 

 attains its northern limit near the Kotukuroa Creek; summit of Tarawera, 

 3,600 feet. 



Gentiana montana, Forst. — Attains the northern limit of the genus at Opepe. 



Gratiola sexdentata, A. Cunn. — Ohinemutu, Rotomahana, etc. I have no 

 note of a more southern habitat for this plant, although it probably 

 occurs throughout the N^orth Island. 



Glossostigma elatinoides, Benth. — Common in the swamps and about the lakes, 

 but has not been recorded from any locality further south. 



Utricularia, n.s. — Amongst Conferva, Rotomahana ; in appearance resembles 

 U. intermedia, but the bladders are attached to the leaves. 



Avicennia officinalis, L., attains its south-eastern limit in Tauranga harbour, 

 northern part. 



Alternanthera sessilis, Br. — Rotorua, the most southern locality yet recorded. 



Plantago coronopus, L. — Native of Europe, naturalized on the beach at 

 Tauranga ; the first notice of its occurrence in the colony. 



Muhlenbeckia axillaris, Hook. f. — Forms compact patches on the Taupo 

 plains south of Oruanui, but is remarkably local, and attains here its 

 northern boundary. 



ChUoglottis traversii, F. von Muell. (Caladenia hifoliay Hook, f.) — Specimens 

 long past flowering ; occurs at Motukino, 1,500 feet, and amongst moss 

 on the summit of Tarawera mountain, where it reaches its northern 

 limit. Distinguished from all other New Zealand orchids by its glan- 

 dular pubescence. 



Thelymitra longifolia, Forst. — Summit of Tarawera mountain, 3,600 feet. 



Sparganium simplex, Huds. — Rotoiti, Rotorua, Rotomahana, etc.
