It will be recollected that the genus Pentstemoii 
{PENTE, STEMON, fifth Stamen) was formed out of 
Chelone. Their only constant distinction is in the 
seeds ; those of Pentstemon being angular, whilst 
Chelone’s seeds have a membranous margin. 
Chelone, too, has woolly anthers; those of Pent- 
stemon are generally glabrous, but this is not a 
certain distinctive character. Our plant is named 
Coboea, from its inflated corolla having some 
resemblance to that of Coboea scandens. 
This species of Pentstemon varies much in the 
colour of its flowers, being sometimes nearly white, 
and its markings indistinct. It is, like Murrayana, 
a rare plant, being of rather delicate habit, and 
requiring ample protection from frost. 
It will flower finely in the borders, but it should 
not be turned out till the beginning of May. Care 
should be taken to fertilize the flowers, so as to 
encourage the production of seeds; and young 
plants should also be struck from cuttings. In the 
autumn, the old plants should be taken up and 
potted in a sandy compost ; and, during winter, be 
thoroughly protected in a cold frame.
