sepals are petaloid, much more developed than the corolla, and 
persistent. Pdilotheca, the flowers of which are pentamerous, may, 
however, be considered as a species of Boronia, with monadelphous 
Eriostemon (Phebalium) eleagnifolium.

stamens, five of which, superposed to the petals, are sometimes 
sterile, surmounted by a small glandular mass. Memafolepis has 
also the pentamerous flowers of Boronia, small, and generally united in 
small capitate masses, with ten fertile stamens ; but the petals are 
united edge to edge in an elongated tube, 
and the base of their staminal filaments is 
lined within by a scale covered with hairs. 
Correa (figs. 429, 430) has the numerous 
flowers, the petals of Nematolepis generally 
joining or resolving themselves into a 
tube, so that the corolla is often described 
as gamopetalous. The stamens are double 
in number to the petals, and all fertile ; 
but the leaves are opposite. In Urocarpus, 
the leaves become alternate, and the flowers 
are nearly those of Hrzostemon; but the
