sepals are petaloid, much more developed than the corolla, and 

 persistent. Philotheca, the flowers of which are pentamerous, may, 

 however, be considered as a species of Boronia, with monadelphous 



Eriostemon (Phebalium) elceagnifolium.

stamens, five of which, superposed to the petals, are sometimes 

 sterile, surmounted by a small glandular mass. Nematolejns 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. 

 Correct (figs. 429, 430) has the numerous 

 flowers, the petals of JVematolepis 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 Urocarpm, 

 the leaves become alternate, and the flowers 

 are nearly those of Eriostemon ; but the 

 carpels are united into one ovary with 

 several cells. Pleurandropsis has, on the 

 contrary, independent carpels, but closely 

 adhering among themselves, except in the thick part of the reflexed 

 stigmatiferous part, five yellow petals with about a dozen stamens,
