The foliage of P. longiracemosa is<br />
much like that of P. fuchsiiflora,<br />
the shape of the leaves showing the same variation. The<br />
arrangement of the inflorescence of the two is very different. From<br />
other species with a racemose inflorescence P. longiracemosa is<br />
readily distinguished by the very thick leaves, which are strongly<br />
glaucous beneath.<br />
