such as occurs in S. lagopus, Raoul and S. saxifragoides, 

 Hook, f., of New Zealand.^ The upper surface is sparsely 

 covered with unusually large simple hairs, somewhat similar 

 to the silky hairs of *S^. lagopus. On the lower surface these 

 hairs are aggregated along the main veins and, assuming 

 a brown colour, are very like bryophytic rhizoids. The 

 petiole, which is \\ to 2 inches long, is also densel}^ covered 

 with these large brown hairs. The ridged flowering stem 

 about 18 or 20 inches high arises later in the season from 

 the axil of the radical leaf. Usually one small leaf, rarely 

 two, veiy similar, except in the absence of crenations, to 

 the radical leaf occurs about 3 inches from the base of the 

 flowering stems (tig. 1, C); no other foliage leaves are 

 present. About a foot above the cauline leaf the stem 

 branches into a loose, very slightly branched raceme. The 

 capitulum is bracteate, shortly pedicellate and droops 

 (fig. 2). It is pear-shaped when young on account of the 

 cohesion of the involucral leaves, which continues as far 

 as is at present known until the beginning of the anthesis. 

 Fruiting capitula (fig. 3) are campanulate and have the 

 involucral leaves free. These leaves separate from the base 

 upwards but remain attached at the tips until anthesis 

 begins (fig. 2). The involucral bracts are six or eiglit in 

 number, the three or four linear-lanceolate leaves over- 

 lapping at their edges the three or four inner, broader, 

 lanceolate leaves. There are thus two series, an inner 

 and an outer of involucral leaves, but since all six or 

 eight are required to complete the circle around the 

 florets, the involucre is described as sub-biseriate. The 

 bracts are _ sparsely covered with short hairs, but the 

 outside of the receptacle and the pedicel immediately 

 below are densely hairy. The receptacle is small, flat, 

 and foveolate. Ray florets are absent; all the 10-15 

 florets are hermaphrodite, regular and tubular campanu- 

 late (fig. 4.). The style (fig. 5) is branched; the style 

 branches are flattened with truncate, penicillate tips ; 

 the apical hairs at the sides of the tips are much longer 

 than is usual in Senecio. The stamens have the typical 

 apical appendages (fig. 6), and very distinct, obtuse,
