A very low densely tufted branched glabrous moss-like plant, forming 

 small cushions rising an inch or less above the ground. 



Leaves closely imbricating, spreading, opposite pairs connate at the 

 base and forming a short membranous sheath, 6-8 mm. long, linear- 

 subulate, acicular, green, with strongly thickened margins, otherwise 

 veinless. 



Flowers near the tips of the branchlets, lateral, shortly peduncled, 

 the peduncles elongating in fruit. 



Calyx deeply 4-partite, the lobes narrow linear-subulate, acicular, and 

 leaf-like. 



Stamens 4, short, inserted between the calyx-lobes and barely half as 

 long. 



Styles 4, short, barely exceeding the stamens. 



Capsule 4-celled, as long as the sepals when mature. 



Hub. — Rocky faces of the Sealey Range, Mount Cook district, at 

 5,500 ft, 



The present species is closely allied to C. canaliculatus T. Kirk. It 

 differs in the number of sepals and stamens, which are uniformly 4 ; in 

 having the stamens and styles much shorter than the sepals ; and in 

 the form of the calyx-lobes, which are linear-subulate and acicular. 



Epilobium microphyllum A. Rich. var. prostratum var. nov. 



Planta typo simillima, ramis omnibus prostratis diffusisque, pedunculis 

 floriferis longioribus. 



Plant similar to the type, except in its prostrate diffuse branches and 

 longer floriferous peduncles.

 of Naseby. D. P. ; Mount Somers, B. C. Aston. 



This curious form maintains its distinctive characteristics over a wide 

 area of the South Island. It occurs on gravelly flats in valley-bottoms.

Caulis erectus, 4-6 dcm. altus. 



Folia parum rigida, 2-3-pinnata. 25-40 cm. longa ; vagina una cum 

 petiolo laminam dissectam aequante vel excedente ; foliola ultima brevia 

 (8-12 cm. longitudine), angusta (4-5 mm. latitudine). 



Innorescentia late oblonga, + 30 cm. longa. 



Bractearum vaginae anguste obcuneatae, in prolongationem 1 2-pinnate 

 divisam foliorum laminis subsimilem productae. 



Pedunculi universales congesti, longiusculi, tenues, sulcati. 



Fructus lineari-oblongus, utraque facie 5-alatus. 



Culms erect, 4-6 dcm. high, rather stout (2\ cm. across in the lower 

 part), strongly grooved. 



Radical leaves numerous, 25-40 cm. long, 2-3-pinnate, pinnae in 4 or 5 

 pairs ; ultimate leaflets crowded, narrow-linear, grooved, slightly rigid, 

 8-12 cm. long, 4-5 mm. broad, spinous at the tips, the margins thickened 

 and delicately erose. 



Sheaths and petioles together equalling or exceeding the dissected 

 blades ; sheaths 8-10 cm. long, 1 cm. broad at the tops, narrow-obcuneate. 

 furnished at either side with a linear spinous leaflet occasionally subdivided 

 and barely half as long as the petiole.
