74 ME. BENTHAM ON LOGANIACE^E. 



flowered cymes are arranged in opposite pairs along a common 

 peduncle, so as to form a kind of compound raceme. The typical 

 species are, F. volubilis, Wall., F. racemosa, Jack, and F. morindce- 

 folia, Blume, which constitute probably but one species spreading 

 all over the Moluccas. We have Jack's own authority that the 

 F. volubilis (of which he had sent the specimens to Wallich) is 

 the same species as his racemosa, and some specimens of the 

 latter can by no means be distinguished from the smaller ones of 

 F. morindcefolia. Both have precisely the same foliage ; and if in 

 F. volubilis, besides the compact inflorescence, the leaves are more 

 acuminate and more contracted at the base than is usually the 

 case with F. racemosa, still there are specimens of that and of F. 

 morindcefolia which have a similar tendency. 



Blume has seven other species of this group, of none of which 

 we have any specimens ; but we have two well-marked ones, 

 perhaps both new ; one is from Mr. Motley's Borneo collection, 

 and must be near F. coarctata, Blume, but with flowers very much 

 larger and differently shaped from those of F. morindcefolia, with 

 which those of F. coarctata are compared ; the other, as it were, 

 a miniature representation of F. racemosa, gathered in Singapore 

 by Mr. Lobb, which may be a form of F. ligustrina, BL, with 

 three flowers instead of one or two to each of the cymes forming 

 the raceme. 



Of the third group with small flowers in supradecompound 

 corymbs our herbaria possess two species. One is F. fragrans, 

 Roxb., introduced into the Moluccas from China, with which F. 

 peregrina, Blume, appears identical. The other is jP. speciosa, 

 Blume, from Java, which is most likely to be the true F. elliptica, 

 Roxb., only known by his very short and incomplete diagnoses. 

 The F. Tcimangu and F. picrophloea referred to this section by 

 Blume are entirely unknown to me ; the author himself has only 

 seen the foliage of one and the foliage and fruit of the other. 



A Penang plant occurs in some herbaria distributed from the 

 Horticultural Society's collections under the name of a Fagrcea, 

 of which it has the stipular expansions of the petiole. Can this 

 be the one shortly described by Martius as Fagrcea malayana ? If 

 so, that species must be rejected from the genus, as upon a careful 

 examination it proves to be merely a few-flowered form of Taber- 

 ncemontana corymbosa, Boxb.
