garden plants of P. angustifolium is greater than that of 
the specimens examined and figured by M. Kunth, so as 
in fact to answer to the terms used by that botanist in 
defining his C. elegans. ' 
It is worthy of remark, that the uppermost filaments, 
which are usually thickened at the base, are in this species 
so much dilated there, as to have become almost petaloid. 
Stem erect, somewhat branched, about two feet high, or 
more, quite smooth, except towards the top, where it is 
minutely glandular. Leaves ovate-lanceolate, amplexicaul, 
acuminate, finely serrulate, the serratures incurved, quite 
smooth, the upper by degrees broader and less serrated, 
at last entire. Panicle erect, terminal, many-flowered. 
Pedicels filiform, glandular. Segments of the calyx linear- 
lanceolate, purple, if viewed with a magnifying glass 
glandular. Corolla tubular, somewhat ventricose, bright 
rose colour, bilabiate, glandular externally ; the upper seg- 
ments oblique, the lower: short, ovate, slightly bearded. 
Upper. filaments very much dilated at the base. Anthers 
exserted (in P. campanulatum not exserted), quite smooth, 
with divaricating lobes. The rudiment shorter than the 
stamens, and. bearded at the apex.
