Colenso. — On new Cryptogams. 241 



sexfariously disposed, very close, crowded, imbricate, spread- 

 ing, of three forms and sizes, (a.) broad and similar to 

 those on main stem but shorter, nerve red-brown ; (/3.) 

 ovate ; and (y.) narrow-oblong, strongly nerved, nerve not per- 

 current, vanishing below apex, tip mucronate, upper margins 

 sharply serrate, nerve at back near top serrate sub 6 teeth ; the 

 ultimate branchlets red-brown, glossy, with the leaves quadri- 

 fariously and more loosely disposed ; perichaatial leaves very long, 

 subulate, ^ line wide at bases, erect, flexuous ; tips piliferous, 

 very slightly and distantly serrulate (sub lente), with 5-7 dark 

 longitudinal plaits, red at bases. Fruit-stalks many, sub 20 on 

 a stem on the upper side of main branches, 1-1 \ inches long, 

 red and smooth (as also capsule), very flexuous, drooping, 

 largely vaginant ; vagina dark-brown. Capsule cernuous, not 

 grooved, obovate-oblong, cylindric, turgid, unequal, lower edge 

 straight, the upper gibbous ; outer teeth incurved when dry, 

 subulate, broad at base, brown, tips pale, closely barred with no 

 medial line, margined with a dark line and a narrow hyaline 

 slightly erose outer margin ; inner teeth pale-yellow distantly 

 barred with brown, their tips brown and filiform, with two long 

 capillary knotty cilite between each tooth. Operculum half as 

 long as capsule, base hemispherical, acuminate with a long obtuse 

 beak. Calyptra dimidiate, 2 lines long, narrow subulate, 

 obtuse, red, glabrous, glossy, cylindrical and entire for more than 

 half of its length. 



Hab. Growing on the ground in large patches among 

 HymenophyUum, in shady forests near Danneverke, County of 

 Waipawa; 1887: W.C. " 



Obs. A fine handsome moss ; its affinities are with two or 

 three other fine dendroid New Zealand species of this genus — 

 viz., I. menziesii, Hook. f. and Wilson ; and I. kerrii, Mitten ; 

 but differing from the former in its differently-shaped and much 

 shorter capsule, hi its pericha3tial leaves not being serrate, and 

 in its larger piliferous stem-leaves ; and from the latter in its 

 nerves not being excurrent ; while from /. marginatum, Hook. f. 

 and Wilson, it also differs in its capsule not being grooved and 

 its leaves not margined. 



2. I. obscurum, sp. nov. 



Plant densely matted ; rhizome creeping, branched. Stems 

 dendroid, erect, 1^-2 inches high, sub-rigid, stoutish, cylindri- 

 cal, bare and ringed below, with a few distant foliaceous scales 

 scattered above ; 3-pinnate, much and irregularly branched ; 

 branches at their bases like the main stem ; branchlets usually 

 short, stiff. Leaves dull green (becoming brownish and dis- 

 coloured in age), sub-quadrifariously disposed, erect, very close, 

 compact, imbricate, spreading, all similar, sub-linear-ovate, 

 entire, acute, nerveless ; cells very minute, narrow-linear, long,
