388 Traiisaclions.— Botany. 



minute irregular lobe, or tooth, at lateral angle, 1-nerved, 

 margins minutely sinuate-crenulate, ^Yhitish, purple-clashed. 

 Fruit oblong, turgid, ribs obsolete. 



Hah. Forming large close-growing patches, or little beds, 

 wood south of Dannevirke, County of Waipa^va; October, 

 1889-90 : W. C. 



Obs. A species near P. tr if oliolata, Hook, (to which I had, 

 at first discovery, assigned it), but very distinct in several 

 characters, in both leaves and flowers. 



Order XXXIX. Composit>e. 

 Genus 9. Cotula, Linn. 

 1. C. vonosa, sp. nov. 



A slender weak sub-erect herb, clothed with long fine 

 silky white hairs, especially on young leaves and flowering 

 stems, 6in.-8in. high ; generally with 1 main slender stem 

 below, much-branched above ; roots long and filiform. Leaves 

 few^, distant, scattered mostly on the lower parts of branches, 

 -|in.-fin. long, broadly oblong or obovate in outline, pinna- 

 tifid with 2-3 pairs of lobes on sides ; lobes sub-lanceolate, 

 simple, entire, sometimes with 1 small lobule on the upper 

 edge of the larger lobes ; margins thickened ; tips acute, sub- 

 mucronate, thickened, white; the apical portion of the leaf 

 broad, 3-lobed, lobes equal ; much veined, also the winged 

 rachis and petiole ; veins intramarginal ; 2 pairs of 

 small lobe-like stipules at base of petiole. Heads small, 

 2 lines diameter, spreading, solitary, terminal on long 

 slender naked peduncles or tips of branches, 3in.-4:in. long, 

 simple, erect, 2-5 rising from a main branch. Involucral 

 scales sub 2-series. Scales broadly oblong, the centre green, 

 with a strong percurrent central nerve, and other nerves 

 branching, their margins being very large membranous pellucid 

 white, delicately and closely reticulately veined ; edges of tips 

 minutely sub-sinuate denticulate, soon Ijecomiug black. Eay- 

 florets in two rows, pediceiled; corolla 0; achene obovate, 

 apex simple retuse ; a few^ fine short hairs in the centre on 

 both sides ; margins thick, broad, glabrous ; styles spreading. 

 Disk-florets cylindrical, 4-toothed ; teeth broad, eglandular ; 

 pedicels long. 



Hah. Forming small patches in open woods south of Danne- 

 virke, County of Waipawa ; 1890 : W. C. 



Obs. A species very near to C. australis, Hook., but differ- 

 ing from that plant in several particulars : as in its great ha;iri- 

 ness, in the smaller size shape and markings of its leaves, 

 in its larger heads, in its difl'erent flowers and achenes, and, 

 particularly, in its beautiful and curious involucral scales.
