receptacular tube forming the " hep." This includes 

 many free carpels, and carries the sepals (free), the 

 petals, and many stamens on the rim above (Fig. 57). 

 The rim is orange-coloured, and looks like a honey-disc ; 

 but it seems to have lost the power of secreting honey. 

 Trihe, Neuradeae. — One genus represents this tribe 

 in South Africa, Gric'lum. It has only ten stamens

and a short tube adherent to the ovary. Hence the 

 latter is now inferior. The petals are large and yellow. 

 The carpels vary from five to ten. The species grow 

 in sandy places and in salt ground. 



Trihe, Pomeae. — This tribe is wanting in South 

 Africa ; but the fruit, is familiar in apples, pears (Fig. 

 58), loquats, and is called a " pome." 



As in Grie'lum, the receptacular tube invests the 

 ovary, but becomes fleshy ; so the above fruits might 

 be called pseudocarps, as the edible part is really the 

 flower- stalk.
