 lobes lanceolate, acute, much shorter than the corolla. Fruiting peduncle erect, 

 exceeding the leaves. Capsule strict, erect, rigid, liu. long. Seeds minutely

A handsome, rare, and local species, not easily mistaken for any other.

f. 91a. 



NORTH Island : Euahine Range, W. E. Andrew ! Tararua Range, Wainuiomata, Buchanan. 

 SOUTH Island : Nelson to Southland. 2,000ft. to 3,500ft. Common by mountain streams, amongst 

 wet shingle, &c. Dec. to March. 



The distant ovate leaves, purple stems, glabrous habit, and large flowers distinguish this from 

 all other species, but small-leaved forms may be mistaken for E. pubens. 



E. nanum, Col. in Trans. N.Z.I, xxvi. (1893) 815. Glabrous, 2Jin. high. Leaves opposite, 

 linear-lanceolate, with 1 or 2 small teeth ; petiole very short, stout. Flowers solitary, subterminal, 

 small. Ovary pubescent with curved hairs. 



High land near Tongariro, North Island. 



It is not possible to discover the affinities of this plant from the description given. Mr. 

 Oolenso states that he had only a solitary unexpanded flower for examination. 



E. {sp.). Specimens of a plant from Campbell Island {Lt. Bathouis) and Clinton Valley 

 (Petrie) appear distinct, but are too imperfect for determination. Stems 5in. long, decumbent or 

 prostrate, emitting short stolons. Leaves all opposite, Iin. long, spreading, shortly petiolate, ovate- 

 oblong, narrowed at both ends, obscurely toothed. Flowers not seen. Capsules few, straight, ter- 

 minal, IJin. long; peduncles shorter than the leaves. Seeds narrowed below, minutely papillose. 

 Should it prove distinct it might be named E. Petriei. 



Hybrid forms are occasionally found, and are usually treated by collectors as varieties of the 

 species which they most nearly resemble. Professor Hausskneoht describes the following : — 



E. junceum x pubens, Monog. 291. 



E. hirtigerimi x junceum, Monog. 292. 



E. Billardierianum x junceum, Monog. 294. 



I have not seen specimens fully agreeing with the descriptions of these forms, and feel very 

 doubtful as to their permanence, but must admit that the results of hybridisation in this and other 

 variable genera have not been investigated by local botanists. 



'OENOTHERA, Linn. 



Calyx-tube 4-angled ; limb cylindrical, 4-lobed, deciduous. Petals 4. Stamens 

 8. Ovary 4-celled ; style 1; stigma capitate, entire or i-lobed; ovules numerous. 

 Capsule linear, d-valved, 4-celled, rarely 1-celled, dehiscing from the apex into 4 valves, 

 the seeds remaining on the axis, rarely indehiscent. Seeds many or few, not bearded. 

 Herbs, rarely suffruticose, with alternate exstipalate leaves. Flowers solitary, axil- 

 lary, or in leafy spikes or racemes.
