MIMULUS ROSEUS. 
such a situation the leaves and flowers will grow remarkably strong ; but it will 
grow in almost any soil or situation, and gives out a powerful musky odour. The 
lutens, and the variety rivularis, spread rapidly if planted by the side of a pond of 
water, particularly the latter ; they both succeed admirably in pots kept standing in 
water. With this treatment the leaves and stems of the rivularis assume a brown 
colour, and the rich brown spot is very conspicuous. Both the luteus and rivularis 
seed freely ; if the seeds be sown in spring, the plants will flower in the autumn, 
and if in autumn, they will flower the following summer. If placed in a hot-house, 
its colours are paler, and less beautiful, although the plant itself grows taller than 
under any other treatment. 
Those requiring the shelter of a frame in winter, as the guttatus and lanatus, 
require similar treatment to the green-house species. 
The green-liouse species and varieties, as the glutinosus , which is now nearly 
lost in our green-houses, the variegatus , Smithii, Youngii, will do in almost any 
rich, light, and porous soil ; but the pots in which they are planted should be placed 
in pans filled with water. 
, That beautiful variety, Smithii , is just coming into flower at Chatsworth ; we 
purpose shortly to give a figure of it and the variegatus on one plate. 
We raised a very beautiful variety from seed bearing some resemblance to 
Smithii, but with a marked difference in its spotting, which we may probably find 
occasion to figure shortly. 
The word Mimulus is derived from mimo, an ape ; whether this idea of an ape 
or monkey was suggested by the shape of the flower or the appearance of the seed, 
in uncertain ; probably it was the former ; roseus originates in the colour of the 
flowers being rosy or pink.
