| Of all plant families the Meliaceae is among the more useful to man, chiefly for its high quality timbers and for the ease with which some species can be grown in plantations. Almost confined to the tropics, its species nevertheless pervade them, and occur, often conspicuously, in a variety of habitats from rain forest to mangrove swamp and semidesert. For its size, the family probably contains a wider range of floral and fruit structures than any comparable group. In what other family is there such a diversity of primitive ‘arillate’5 seeds, side-by-side with such an array of derived fruits and seeds, and still connected by intermediates? Or, to take the flower, where else can be found such a diversity of forms, from the minute, but structurally complex,... |

| Of the genus Vavaea, occurring from Sumatra to Fiji, 356 collections were studied for taxonomical purpose, some collected in spirit by the author himself. Pollen (31 collections) and wood (12 collections) were also studied. Sex dimorphism occurs in V. amicorum, three sorts of plants being distinguished. The systematic position within Meliaceae comes in the Melioideae, between tribes Turraeeae and Trichilieae, more closely related to the latter. Within Vavaea two sections are distinguished, one of which is new. Four species are distinguished, among which is one new species, V. tubiflora, from New Guinea. A detailed study revealed that one of them, the type species V. amicorum, is an extremely polymorphic species with about 20 synonyms; a special chapter is... |
