OF ORNAMENTAL ANNUALS.

It is quite hardy, and grows readily in a warm dark situation and peat earth. The seeds should be sown very 
thinly ; but from their small size it is very difficult to do this without mixing them with sand, or wood-ashes 
before they are sown. When the young plants come up, they should be thinned out. Tiie flowers are produced 
in great abundance ; but they are generally of very short duration, and usually close about mid-day. 
OTHER SPECIES OF MIMULUS. 
M. MOSCHATUS, Lindl. 
A procumbent plant, rooting at the joints, and producing abundance of yellow flowers, and growing freely 
from seed. 
M. HARRISONII, Paxt. and ovxfic/. 1, in PI. 39*. 
A very strong plant, growing about three feet high, a hybrid between M. cordinalit and M. roseus. Like 
all the plants belonging to the genus, it seeds freely ; but the flowers raised from seeds of the same plant vary 
exceedingly. 
GENUS X. 
ALONSOA, Ruiz el Pavon. THE ALONSOA, OR MASK-FLOWER. 
Lin. Sytt. DIDYNAMIA ANGIOSPERMIA. 
Generic Character. — Corolla subrotate, resupioato from the twisting of the pedicels. 
1.— ALONSOA LINEARIS, Ruix et Pavon. THE LINEAR-LEAVED ALONSOA, OR MASK-FLOWER. 
Synonymes. — Celsia linearis, Jacq. ; Hemimeris coccinea, Willd. ; 
H. linariaofolia, H. B. et Kunth ; Hemitomus fruticosua, L'Herit. 
Derivation. — The genus is named in honour of Don Zanoni 
Alonso, a Spanish consul in South America.

t. 240 ; ? Bot. Cab. t. 1456 ; and om-fig. 7, in Plato 44. 
Specific Character. — Glabrous ; leaves opposite, or three in a 
whorl, linear, entire, or remotely denticulated. — (G. Don.) 
Description, &c. — Nothing can exceed the brilliant colours of the flowers of this little plant, which, though 
generally considered a greenhouse shrub, is found to succeed quite well when grown as an annual in the 
open air. It is a native of Peru, whence it was introduced in 1 790, and was at first called Celsia linearis, by 
which name it is still generally known in the nurseries and seed-shops. It was first treated as a hothouse shrub ; 
it was then removed to the greenhouse, and afterwards, being found to ripen abundance of seeds, it was grown as 
a tender annual ; but it is now found to succeed even if sown in the open ground. To secure a fine show of 
flowers, it is, however, generally thought best to raise the seeds on a slight hotbed, and to plant them out in May, 
and thus treated, the plants will produce a succession of brilliant flowers throughout the whole summer. 
A. intermedia, Lodd. Bot. Cab. t. 1456, is a hybrid between this and the following species, A. incisi/olia. 
Specific Character Glabrous ; leaves opposite, ovate, acute, 
deeply toothed, or 8errated.^-(G. Don.) 
2.-AL0NS0A INCISIFOLIA, Ruiz et Pavon. THE CUT-LEAVED ALONSOA, OR MASK-FLOWER 
Synonymes. — Celsia urticifolia, Curt. ; Hemimeris urticifolia, 
WUld. ; Alonsoa grandiflora, Hort. 
Engraving. — Bot. Mag. t. 417. 
Description, &c. — Larger and stronger-growing than A. linearis, but with rather darker and less splendid 
flowers. It is a native of Chili, introduced in 1795, and requires the same treatment as the preceding species, 
but is hardier. Both kinds require a loamy soil and an open situation. Seeds may be purchased in the seed- 
shops under the name of Alonsoa grandiflora, _^_
