X. I TUBAL niSTOBY OF PLAXTS. 



Their trunk is often simple, 1 and their summit bears a crown of 

 alternate leaves, more or less near together, petiolate, exstipulate, 

 with a simple digitinerved limb, more or less cut, or more rarely 

 compound-digitate, with a number of leaves varying from five to 

 twelve. The flowers are axillary, or disposed upon the wood in 

 simple racemes, or in clusters of cymes, without bracts. 



IX. TURNEBA SERIES. 



Turner a- (figs. 339-342) has regular flowers generally herma- 

 phrodite. The exterior perianth, or calyx, has the form of a tube, 3 di- 

 lating above into a funnel or bell shape, and dividing at this point into 

 oblong plates, linear or lanceolate, disposed in quincuncial prseflora- 

 tion in the bud. The corolla is formed of five petals alternating 

 with the divisions of the calyx. They are most generally inserted 

 near its throat, and are much developed, so as to be represented by 

 large coloured membranous plates, 4 oboval-rounded or spathulate, 

 with a short claw, and they are disposed in contorted prsefloration in 

 the bud. But there are certain species in which the petals, little 

 developed, not very brilliant in colour, are reduced to tongues 

 which do not surpass or even attain to the height of the sepals, 

 while they are too narrow to cover or touch each other, even in 

 the bud. 5 



In one of the species, distinguished under the generic name of 

 Erblichia,* the claw of the petal is crowned by short threads. The 

 androceum is formed of five stamens alternate with the petals, and 

 either inserted on a level with them, or more usually lower down on

*. 3 This tube is probably of the nature of a 

 receptacle, and on this account comparable with 

 Samyda. If so, it would be better to say that 

 the sepals are free, or nearly so, and that the 

 true calyx only commences with the insertion of 

 the petals.
