The name of this genus was adopted after Zac- 
cheus Collins, an American botanist. 
At No. 391 of the Botanic Garden, we published 
Collinsia grandiflora, a plant which obtained its 
name, large-flowered, by a comparison of its flow- 
ers with such species as had then been introduced. 
It is now, however, rendered inapplicable, by the 
discovery of the present plant, which excels it in 
the size of the flowers, in general showiness, and 
also in height. Names founded on comparison 
will always be subject to the same inconvenience 
till that time when all the plants on the face of the 
earth shall have been collected and arranged — a 
period, by the bye, of which it is impossible for 
the human mind to catch the least conception. 
Collinsia bicolor, from the abundance of flowers 
which it produces, is a most desirable low annual, 
growing in any common soil, and bearing our 
severest winters whilst the plants are small. Au- 
tumn sown plants will flower in May and June; 
and an early and late sowing, in spring, will 
produce flowers in succession till October ; or till 
autumnal frosts destroy them.
