Specific Character. — Plant a hybrid, with much of 
the habit of M. cardinalis, but having rather more 
expansive flowers, which are of a deep crimson hue, 
with a dark brownish purple centre. 
We procured our drawing of this very showy hybrid from Messrs. Rollisson,' of 
Tooting, with whom it flowered profusely last summer. At the present period it 
is to be met with in most of the London nurseries, and is undoubtedly the hand- 
somest plant of the kind yet produced. 
It appears to have been raised by Mr. Maclain, florist, of Harold's Cross, near 
Dublin, and to have been named after this person by Sir W. J. Hooker. 
M. roseus is stated to be one of the parents ; and there can be little question that 
M. cardinalis was the other ; for it approaches more nearly to the latter species 
than to any known kind. Its habit, indeed, is precisely the same ; though, 
perhaps, it is rather more dwarf and compact. The flowers, moreover, are of a 
similar shape, varying somewhat in the degree of their expansion, and occasionally 
being broader, flatter, and less reflexed, than they are shown to be in our figure. 
The drawing, however, accurately represents the ordinary form. 
Such is the extreme richness of the colours of the blossoms, that while our 
colourers have attained it as nearly as possible, nothing can reach the splendid hue 
of the throat, w 7 hich has a raised hairy and velvety-looking surface, of an exqui- 
sitely superb deep blood-coloured tint. 
At Messrs. Henderson's, Pine-apple Place, and in other nurseries, there is a 
very good hybrid Mimidus, apparently of similar origin to the present, but having 
flowers more like those of M. roseus. They are more open than those of 
M. Maclainianus, and of a light rosy crimson hue. It is not nearly so handsome 
as the plant now figured.
