Colenso. — On new Cryptogams. 251 



denticulate ; sub-imbricate and closely adpressed at their dorsal 

 bases completely hiding the stem ; their ventral bases patent. 

 Stipules patent, cordate, bifid ; apices obtuse ; margins sub- 

 ciliate-denticulate ; cilia? free, rather distant ; bases sub- 

 amplexicaul. Cells oval and sub-orbicular, smaller at margins, 

 larger oblong and parallelogrammatic in the centre and at the 

 base. 



Hab. High lands, interior, north of Napier; 1886 : Mr. A. 

 Hamilton. 



Obs. A truly graceful species ; pretty nearly allied to 

 I. lyallii* Hook, fih, but differing in size, colour, shape of 

 leaves and stipules, and in the form, etc., of its cellules. Its 

 delicate rose-pink colour, alike throughout, enhances its beauty, 

 and makes it an attractive and elegant object. 



Genus 17. Trichocolea, Nees. 

 1. T. elegans, sp. nov. 



Plant prostrate, spreading in thick matted tufts or patches, 

 with rather long creeping stems or ultimate branches (2-3 

 inches), bright green, sub-quadri-pinnate. Stems minutely and 

 closely hairy, their leaves broadly transverse rather distant ; 

 secondary branches bipiunate, horizontal, broadly ovate or 

 rhomboid in outline, presenting a regular fern-like appearance ; 

 branches and branchlets cylindrical, symmetrical, radiating, 

 spreading ; ultimate branchlets compacted, sub-globose, and pale 

 at tips. Leaves numerous, sub-verticillate ; segments wholly 

 capillary, branched, jointed, acute, implexed. Stipules multifid, 

 capillary spreading, much like leaves. Peduncle very stout, 1 

 line long, succulent, slightly hairy, erect from upper surface of 

 branches near top of frond, sometimes geminate. Calyptra 

 oblong, scaly, very hairy at top, hairs whitish, spreading ; scales 

 long, ovate-acuminate, laciniate-ciliate, recurved. 



Hab. On rotten logs, wet shaded woods, Norsewood, County 

 of Waipawa ; 188G ; and also near Danneverke, same county ; 

 May, 1887 ; W.C. Glenross, County of Hawke's Bay ; October, 

 1887 : Mr. D. P. Balfour. 



Obs. This is a truly elegant little plant ; its pleasing green 

 tufts, with their central short flat bipinnate radiating branchlets 

 symmetrically disposed, give it a very neat appearance ; which 

 is still further heightened by its long slender creeping stems or 

 branches. While in shape and babit it differs largely from its 

 congeners, T. tomentella and T. lanata, yet it approaches them 

 pretty nearly in the form of its leaves and stipules ; which, 

 however, are still more multifid and capillary. 



* Originally discovered on the summits of the neighbouring high moun- 

 tain (Ruahine) range.
