BOTANY OF VICTORIA. 361 
this time, I have been unable to make up such a collection by the * Red 
Jacket’ as would have been worth sending to you; as this however is 
one of the regular clippers, I will not lose time in forwarding to you a 
few lines. 
Professor Harvey, that excellent and learned man, will leave our 
shores in a day or two for Sydney, proceeding probably to Moreton 
Bay. You may imagine what pleasant hours I have spent with him. 
He supplied the Government collection and my own herbarium with a 
beautiful set of Ælyæ, and had the kindness to arrange my own, so that 
I have ample materials for working now and then a little at this inter- 
esting order of plants. We made also some selections of duplicates 
from my Phanerogame for the Dublin collection. 
In a letter, which I despatched about a fortnight ago, I gave some 
additional information on the flora of the Alps, having subjected several 
of my plants to an analysis, viz. Caltha .Nove-Zelandie, Boronia algida, 
Phebalium ovalifolium, Drapetes Tasmanica, Diplaspis Hydrocotyle, Ra- 
nunculus anemoneus, Euphrasia alsa, Drosera Arcturi, Ranunculus Mil- 
lani, Herpetolirion Tasmania ?, a new genus of Umbellifere, distinct 
from all in having ten petals, or rather five petaloid sepals = Dichope- 
talum ranunculaceum, Pederota densifolia: there are, besides, a few 
other beautiful species, but I have not yet examined them. 
Our botanic garden offered also two new plants this year: one, 
Greevesia cleisocalyz, was raised from seeds collected by Mr. Bunce, in - : 
the second expedition of the unfortunate Dr. Leichhardt: it isa most — 
extraordinary genus of Malvaceae, differing from Pavonia and the thou- 
sand other known species of the Order in having a closed calyx? which 
bursts only when the fruit becomes perfectly ripe: the little corolla 
never expands, and sees consequently zo daylight until long after fe- 
eundation! The other is a herbaceous Sesbania, allied to S. picta, 
which, as the species mentioned" by Sir Thomas Mitchell remained — 
undescribed, I will call Sesbania Australis; Mitchell’s plant however 
must be distinct, for mine is not allied to S. aculeata. I have been 
also fortunate enough to discover a third new genus of Malvacee on 
Lake King. I was at first reluctant to remove it from Lagunea ; but 
the undivided style, with a trilobed, club-shaped stigma, the trilo- 
cular capsule, which encloses a slight quantity of free short hair, the 
habit of the plant, and what may seem extraordinary, the suppression : 
of stipules, induced me to separate it as i Mattia trilocularis. —
