“…Taylor (1983) considered this evidence to indicate that Harrisonia and the subfamily Spathelioideae occupy a "rather unclear junction area" of Rutaceae, Cneoraceae, and Ptaeroxylaceae. Ptaeroxylon lacks limonoids but possesses the pyranochromones that are otherwise restricted to Harrisonia, Spathelia (Rutaceae), and Cneorum (Cneoraceae) (White, 1986). Alkaloids have also been shown to be absent from both Harrisonia and Cneorum (Waterman, 1983), although they are known to occur in Rutaceae and Meliaceae, as well as Simaroubaceae s.s. (Mester, 1983).…”

The constitution of this clade approximates the broad concept of Sapindales (sensu Cronquist). Five lineages within the order are recognized: a "rutaceae" clade (Rutaceae, Cneoraceae, Ptaeroxylaceae, Simaroubaceae sensu stricto, and Meliaceae); a "sapindaceae" clade (Sapindaceae, Aceraceae, and Hippocastenaceae); Anacardiaceae plus Burseraceae; Kirkiaceae; and Zygophyllaceae pro parte. Relationships among these groups were only weakly resolved, but there was no support for the recognition of the two more narrowly defined orders, Rutales and Sapindales sensu stricto. Several families that have previously been allied to Sapindales or Rutales show no affinity to the core sapindalean taxa identified with the molecular data, and are excluded from the order: viz. Akaniaceae, Bretschneideraceae, Conneraceae, Coriariaceae, Melianthaceae, Meliosmaceae, Physenaceae, Rhabdodrendraceae, Sabiaceae, Staphyleaceae, Stylobasiaceae, Surianaceae, and Zygophyllaceae sensu stricto.

“…Freiburghaus et al (1996) also investigated the activity of leaf extracts of T. roka, which is now named T. emetica subsp. emetica (White, 1986), which were inactive. In our work, we showed that the T. emetica leaf extracts (methylene chloride and water) possess interesting activities.…”

The in vitro antitrypanosomal activity of methylene chloride, methanol and aqueous extracts of the leaves and twigs of five plant species traditionally used in Benin for the treatment of sleeping sickness were evaluated on Trypanosoma brucei brucei and their selectivity was analysed on Leishmania mexicana mexicana and J774 macrophage-like murine cells. The results showed that the four most active extracts had MIC values ≤19 g/ml (Hymenocardia acida twig and leaf, Strychnos spinosa leaf, Trichilia emetica leaf methylene chloride extracts).All these extracts had a lower activity on L. m. mexicana and J774 cells. Determination of the IC 50 values of the methylene chloride leaf extracts on two strains of trypanosomes (T. b. brucei and T. b. rhodesiense) and two mammalian cell lines (L6 and J774 cells) showed that all extracts possessed some antitrypanosomal activity with IC 50 's ranging from 1.5 to 39 g/ml. All were also toxic to the mammalian cells, but usually with higher IC 50 's. The only exception was the S. spinosa methylene chloride leaf extract which had no toxicity on J774 cells. Although tannins have been identified in most of the species studied, they could not be detected in the most active extracts, just as alkaloids. The presence of flavonoids and quinones may at least in part explain the observed activities of some of the active extracts.

“…Many species inhabit secondary forest, and drier, more open vegetation, with a few in semidesert. As White (1986) commented, "In its ecology the Meliaceae is more diverse than most tropical families of comparable size…".…”

“…From West Africa to Uganda Ekebergia capensis occurs in savanna woodland and drier parts of the rain forest region, while in east and southern Africa it is mostly in montane forest, riparian forest, and temperate forest (as at Knysna in South Africa). White (1986) wrote: "Because it occurs in more than one major vegetation type and more than one regional phytochorion, it is an ecological and chorological transgressor…", The neat allopatry among Ekebergia, Quivisianthe and Sandoricum (Fig. 23) suggests that none of the genera have spread very far.…”

Biogeography and ecology in a pantropical family, the Meliaceae

This paper reviews the biogeography and ecology of the family Meliaceae and maps many of the clades. Recently published molecular phylogenies are used as a framework to interpret distributional and ecological data. The sections on distribution concentrate on allopatry, on areas of overlap among clades, and on centres of diversity. The sections on ecology focus on populations of the family that are not in typical, dry-ground, lowland rain forest, for example, in and around mangrove forest, in peat swamp and other kinds of freshwater swamp forest, on limestone, and in open vegetation such as savanna woodland. Information on the altitudinal range of the genera is presented, and brief notes on architecture are also given. The paper considers the relationship between the distribution and ecology of the taxa, and the interpretation of the fossil record of the family, along with its significance for biogeographic studies. Finally, the paper discusses whether the evolution of Meliaceae can be attributed to 'radiations' from restricted centres of origin into new morphological, geographical and ecological space, or whether it is better explained by phases of vicariance in widespread ancestors, alternating with phases of range expansion.
