latter readily separating, leaving the receptacle closely covered with 

 these persistent stipites. Male flowers central, numerous, developing 

 no achenium ; corollse about 1'" long, yellowish. Anthers 4, pale- 

 yellow, i-i"' long, acute at the apex, without appendages at the 

 base. Style simple, enclosed. Stigma truncate, very slightly divided 

 in the middle. 



It is not without hesitation that the author draws this remarkable 

 plant to Leptinella. Had the analysis revealed any appreciable 

 structural differences in the organization of the flowers from those 

 of the complex of the known species, our plant would as Traversia 

 have been raised to generic distinction. But to the mere habitual 

 disresemblance of this new member of the genus Leptinella can 

 hardly more value be attached than to the external dissimilarity of 

 Cotula australis to C. coronopifolia. From Myriogyne, a genus to 

 which Sphseromorphsea must be reduced, it differs already in the 

 want of the development of achenia of the bisexual flowers and in 

 their simple stigma. The genus Trineuron, to which Ceratella 

 might be joined, stands still more distant. Whether, however, it 

 would not be preferable to bring all Leptinellse to Cotula, to which ' 

 some species, indicated by C. Koch under Pleiogyne (Schlecht. & 

 Mohl, Bot. Zeitung, i. 40) offer a transit, must by a future careful 

 revision of all existing allied plants be decided. 



The wjiter selected this plant, one of the mos't interesting of 

 those of the Chatham-Islands, for bearing the name of the Honorable 

 Dr. Featherstone, Government-Superintendent at Wellington, New 

 Zealand, as a mark of recognition of the favor shown by that able 

 ofiicer in introducing some years since .a number of living plants 

 from the Chatham-Islands into the Melbourne Botanic Garden. 



It would be desirable to ascertain the duration of this species. 



Leptinella potentillina. 



Stems creeping, soft-downy ; petioles towards the base membra- 

 nous-expanded and clasping; leaves pinnatisected, finely gland- 

 dotted, almost glabrous ; segments of the leaves suhovate, with 

 duplicate short teeth or minute toothed lobules ; peduncles axillary, 

 many times longer than the capitula, soft-downy ; capitula with 

 very numerous sessile flowers ; scales of the mvolucre about thvrty, 

 arranged in several rows, almost smooth ; the outermost semilan- 

 ceolate, acute; the others semioval and cuneate-oval ; receptacle 

 hemispherical; corollce of the female flowers almost semiovate,
