I t is certainly a valuable addition to our autumnal annuals,
as it continues to bloom from August to November, if the
weather continues favourable, requiring only to be sown in
the open ground; or it may be rose in pots, in frames, or on
an annual bed, and from thence be transplanted into the
open borders.
The generic name is derived from tjXioe, the Sun, and
avffog, a flower.
1. Scale of the chaff at the base of one of the florets of the disk. 2. One of the Rays cut
off, showing the barren Stigma. 3. Floret of the disk spread open to show the nerves.
4. The 5 Stamens, the iilaments distinct, and anthers united into a tube. 5. Akenia or
Seed, termmated by 2 aristas, and surmounted by the style, and bifid stigma. G. Capitu-
lum cut through the middle to show the chaff on the receptacle.

“ The seeds of the above interesting plant were obtained from specimens
collected in thickets, near Jalapa, in September, 1829, by Messrs. Deppe
and Schiede, two German Botanists, who have been for some time in Mexico.
Dr. Schiede states it to be rare. I t was at first supposed to be the same
with the species of Sesse and Mocinno, described in the fifteenth volume of
the Linnean Transactions; but a more accurate comparison proves it to be
essentially different; a separate character and name being, therefore, necessary,
we propose the following for it.”
L. erubescens, foliis triangulari-cordatis grossii inaequaliterque serratis
pubescentibus, calycis segmentis oblongis mucronulatis, filamentis simplicibus.

“ The posterior lobes of the leaves are truncate, and the pubescence
shorter, and mostly, if not always, inarticulate; while in L. scandens, the
leaves are cordately ovate, with short rounded lobes, and clothed, as well
as the stem, with long jointed hairs ; the lateral nerves are free to the base ;
the teeth are sharper, the calycine segments are attenuated into a long acuminate
point, and the filaments are geniculate below the middle. The rudiment
of a fifth stamen noticed by my accurate friend, Mr. Sweet, in L. erubescens,
I find to be also present in L. scandens, which, like the former, has
probably, likewise, a suftruticose stem.”
“ The Lophospermum physalodes proves to he the type of a new genus
akin to Gemrdia, which may be characterised as follows.”
G A S T R O M E R IA . Calyx subglobosus, memhranaceus, infiatus, 6-
dentatus. Corolla campanulata, basi suhaequali; limbo 5-loho, bilabiato.
Stamina 4 , didynama : fiiamenta simplicia, glabra : antherce ohlongse -. loculis
superne confiuentibus, basi solutis, divergentibus, muticis. Ovarium
biloculare : Septo utrinque placentifero : ovulis minutis, angulatis, numerosissimis.
Fructus —-Frutex (Mexicanus) setulis eallosis scaber. Folia
opposita, subpetiolata, oblonga, acuta, dentata, pinnati-nervosa. Flores
axillares, solitarii, pedunculati. Pedunculi uniflori, bibracteati. Calyx vi-
rens. Corolla, magna,pu7-purea? sesquipollicaris. D . Don Mss.
W e have lately seen fine specimens o f L. seândens, in Mr. Lambert’s Herbarium,
and find it is perfectly distinct from our plant, and a still finer species,
a branch about a fo o t long, having a dozen open flowers on it. Our plant at
folio 68, must, in future, bear the name of L. erubescens. R . Sweet.
