the panicle as being much larger — " 3-4 pedalis " — with other 

 differences, as " ovula in loculo 5-6," and the plant to be 

 " 10-20 pedalis." (" Enurn.," v., 30.) 



Genus 6. Arthropodium ? Brown. 



1. A. ramulosum, sp. nov. 



Plant small, slender, glabrous. Leaves 10, prostrate, 

 spreading around stem subrosulate, linear-lanceolate, 9in.- 

 lOin. long, 3 lines wide,. 3 innermost widest, concave, very- 

 acuminate tip acute, base half-clasping, membranaceous, 

 flaccid, somewhat curved or subfalcate, dark-green, much 

 parallel-nerved and striate on under-surface and so the cauline 

 leaves. Stem single, erect, 18in. high, purple, slightly genicu- 

 late at nodes, 12-branched, base 1£ lines diameter, apex 

 flowering ; branches green, striate, alternate, distant, the 

 lower ones 7in. long, decreasing gradually in size upwards, 

 the uppermost 3iin. long at 4in. from tip of stem, spreading 

 horizontally ; the lower branches 2in. apart on stem, the 

 upper ones sub lin. ; no branch at lowest node Hin. from 

 base, but a simple very long cauline leaf or bract 7in. long ; 

 at the lowest node of the basal branch a branchlet l^in. long 

 2-3-flowered, and at 2 nodes next above on same branch 

 2 flowers from each (this peculiarity also occurs at the lowest 

 node of the apical portion) ; at the base of each branch are 

 2 leaf-like cauline sessile linear-acuminate bracts, the longer 

 one 5in. long 3 lines wide, with a minute lilac-coloured mem- 

 branaceous bracteole in the axil between branch and stem 

 (also in the axils of all the branches), 2-nerved, tip acute and 

 bifid. Flowers scattered, generally 12 on the longer branches 

 each fin.— |in. apart ; pedicels |in. long, slender, jointed above 

 middle, all bracteolate with long green bracteoles. Perianth 

 small white, segments 2 lines long, narrow-oblong nearly 

 alike, reflexed, each having 3 faint -longitudinal medial lines 

 (or nerves) parallel and close, the 3 outer segments stouter 

 margins entire, tips subacute and thickened, the 3 inner very 

 membranous margins slightly denticulate-erose, tips trun- 

 cate ; filaments white shorter than perianth 1J lines long 

 erect spreading, their upper two-thirds densely hairy bushy 

 throughout, extending close up to anther ; hairs white stout, 

 glistening, tips obtuse ; anthers small ^in. long, pale, linear ; 

 .style erect a little longer than anthers ; stigma simple, capi- 

 tate, flat, spreading ; ovarium green glabrous scarcely 1 line 

 long rounded-oblong. 



Hab. In a rocky spot near Mangatoro, south of Danne-
