though in Australia Acacia surpasses all others largely in 
the number of specific forms. The species of Senecio, as 
representatives from almost every part of the globe, become 
thus of the greatest possible interest, and are certain to be 
always among the first which come under the notice of any 
phytographical observer. The groundsels, 1 may- remark, 
though generally of the more humble forms#of vegetation, 
present, in a recently discovered species from the Chatham 
Islands (Senecio Huntis: “ Vegetation of the Chatham Islands,” 
sketched by F. M., p. 23, plate 3); and in the Victorian and 
Tasmanian S. Bedfordii (F. M., report, 1858, 26) fair-sized 
trees, perhaps the only truly arborescent species of the globe. 
In transmitting the botanical object, to which more 
specially this brief memoir has reference, the discoverer 
justly observes, “its nearest affinity to be with Senecio 
“ Paucifolius, from which however it abundantly differs in 
“its peltate leaves. The leaf is very like a frequent form 
“of S. Oxyrifolius, but that plant has discoid capitula and 
“a corymbose-paniculate inflorescence.” In these lucid 
remarks I cannot but fully concur, and it will be therefore 
with these two congeners that Mr. MacOwan’s Senecio wil 
rank under the highly appropriate name chosen by that 
gentleman for this new species. It may however be that 
occasionally monocephalous varieties of S. Paucifolius and 
S. Oxyrifolius are formed ; and again, forms of S. Tropwoli- 
folvus with more than one capitulum, and thus the affinity 
between these evidently closely allied plants would become: 
still nearer. The diagnosis would approach to the follow- 
ing :— 
Senecio Tropeolifolius (MacOwan) :—Herbaceous, gla- 
brous; leaves small, peltate, cordate-orbicular, or verging 
into a rhomboid or renate form, repand, all radical or crowded - 
towards the base of the stem, on long petioles; stem simple, 
scapelike, monocephalous, with very few distant minute 
scales ; involucre without calycular bracts, unless one, as long 
as the discal flowers, consisting of about 13 scales; ray- 
flowers yellow, about twice as long as those of the disk ; 
achens glabrous.

The only specimen transmitted, is about a span long, and 
without root, which probably will prove tuberous. Petioles 
1-2" long, slender; leaves measuring about one inch, without 
distinct teeth ; the point of insertion about one-third above
