NORTH -INDIAN SPECIES OF IMPATIENS AS BORDER PLANTS. 199 
situation appropriate to them. One of the most suitable posi¬ 
tions would be as single specimens planted out on a lawn, or in 
a select parterre, where, from the beautiful regularity in the 
distribution of their lateral branches, they would form very ele¬ 
gant objects. It would be necessary, however, that the situation 
should be a sheltered one, or the plants would be quite spoiled 
by strong winds, it being impossible to tie up the lateral 
branches without destroying the symmetry in which they are 
naturally arranged, and thus striking a fatal blow to their effect 
in an ornamental point of view. 
The species which are best adapted to this mode of growth 
are, I. macrochila and I. glanduligera. I. Candida is said to be 
in a trifling degree more delicate ; but I have not had an oppor¬ 
tunity of noticing it in this character. I. rosea is a small pink- 
flowered species; and I. tricornis, a yellow-flowered, small¬ 
growing kind, is perhaps the least ornamental of those which 
are in the hands of cultivators. 
It may not, perhaps, be altogether out of place here briefly 
to notice our native species, which, although they are not gene¬ 
rally cultivated, are in many respects deserving of attention. 
They cannot claim to rank amongst the Indian species we have 
been noticing, as regards their abstract beauty; but they are, 
nevertheless, elegant in their habit, and the colour of their 
flowers would make them a pleasing contrast with the red- 
flowered kinds : they possess equally with them those irritable 
properties, which, doubtless, from their curiosity, procure them 
some admirers. I. Noli me tangere (the common Touch me not) 
has large pale-yellow flowers, with faint markings of red about 
the throat, and is said to grow plentifully in some parts of 
Yorkshire and Westmoreland, and also in Wales. The other 
species, I.fulva, which has been regarded as an American plant, 
can scarcely with justice be denied a place in our British 
Flora : it differs from the preceding in having smaller flowers, 
which are thickly dotted with very conspicuous crimson spots; 
and by the union of these two colours that peculiar shade or 
hue is produced which has led to the adoption of the specific 
name. I have gathered it plentifully on the banks of the river 
Wey, in the neighbourhood of Guildford in Surrey, and it is 
stated to grow also near several of its tributary streams; but 
beyond this it has no recorded habitat that I am aware of. The
