310 NATURAL HISTORY OF PLANTS. 



oppositifolious, the calyx wide cupular slightly dentate, and the lobes 

 of the corolla short funnel-shaped and rounded. 



Pelagodendron,^ a Randia of the Viti isles whose gamosepalous 

 calyx breaks irregularly into two or three unequal lobes. 



Sphinctanthus,^ an American Genipa with terminal flowers, -solitary 

 or few, the corolla of which is contracted towards the summit of its 

 rather short tube. 



Leptactinia,^ a Gardenia of tropical Africa whose flowers are united 

 in terminal corymbiform cymes, with the calycinal folioles developed 

 and wide stipules. Dictyandra,* from the same country, difiers 

 essentially onlyan its large flowers with sessile and locellate anthers, 

 and is to the true Leptactinia what Anomanthodia is to Randia proper.* 



In New Caledonia are Genipas allied to Gardenia, whose ovary 

 becomes elongate and so narrow that the seeds are in a single 

 longitudinal series; they are separated from each other by threads, 

 and the entire fruit in its form resembles some siliquas ; hence the 

 name Siliquorandia ^ given to this section. In other plants of the 

 same group, the seeds, not numerous, are elongated at one extremity 

 to a short wing, like that we have described in Olostyla, and the 

 flowers, very small, are grouped in glomerules in the axil of the leaves. 

 They have been named FaragenipaJ Randiella ^ also has very small 

 flowers springing from the wood of the branches. The style is dilated 

 above to a stigmatiferous sphere. They are from New Caledonia. 

 Other peculiarities, more important still, characterize Xylatithorandia,^ 

 whose large flowers with funnel-shaped corolla, recalling those of 

 Amaralia and Gardenia Annce, grow from the wood of the branches. 



Thus defined, this very extensive genus '" comprises about
