Descriptive Characters of 



shorter than the petioles; leaves pinnatisected, glabrous or 

 together with the upper part of the petioles scantily downy; 

 segments few, linear, undivided or bi-trisected, terminated by 

 a gland ; sepals appressed, glabrous, nearly ovate, with 

 membranous margin; petals five-ten, white, obovate or 

 oblong-cuneate, almost twice as long as the calyx; nectar-pit 

 distant from the base, margined, covered by a hardy percepti- 

 ble scale; carpels few, glabrous, broad-ovate, compressed, 

 margined, smooth, with a hooked style. 



In gravelly places on most of the summits of the Australian 

 Alps, irrigated by the melting snow. 



I should have referred this neat little plant to the Tasma- 

 nian E. nanus, were the discrepancy in the colour of the 

 petals, a character of such validity in this genus, not too 

 manifest ; for whilst to that species bright yellow petals are 

 attributed, I found them always white in this, and assuming 

 only a slight yellow tinge when drying. 



In selecting the specific .name, I desired to pay a slight 

 scientific tribute to the merits of A. M'Millan, Esq., who 

 not only forced, with skill and enterprise his way first into 

 Gipps' Land, opening one of the finest districts of vfhole^- 

 Australia to civilisation, but who also named and first ascended' 

 Mount Wellington, where I became originally acquainted' 

 with this plant. 



3. Caltha introloha. 



( Sect. Psychropldla.) 



Dwarf, leaves on long petioles, hastate-ovate, notched at 

 the summit, perfectly entire, enlarged at the base by two 

 long lobes; these bend inward, oblong-linear, below dilated; 

 scape with one flower, very short; sepals white, five-eight, 

 deciduous, lanceolate-linear, acuminate ; carpels five-nine, 

 with three seeds, and a long straight style, reflexed at the 

 top. 



On gravelly places in the Australian Alps, irrigated during 

 the summer months by the melting snow. Mount Hotham, 

 Mount Latrobe, and Munyang Mountains. 



To be distinguished from C. Novae Zeelandia? principally 

 by its white flowers, and longer leaf- lobes. It is the only 

 species known from New Holland.
