TL;DR: The Cenozoic fossil record of Humiriaceae in South and Central America, together with discreditation of former reports from Europe, strongly supports a Neotropical origin for this family.
Abstract: To place a new fossil occurrence of Sacoglottis in a broader context, we surveyed the fruit morphology of all extant genera of the Humiriaceae, conducted a cladistic analysis, and critically reviewed the fossil record for this family. Living and fossil fruits of Humiriaceae are recognized by a woody endocarp, germination valves, and, in some genera, wall cavities. The phylogenetic analysis based on 40 morphological characters yielded two most parsimonious trees indicating Vantanea as sister taxon to all genera among Humiriaceae. Schistostemon is indistinguishable from Sacoglottis in fruit morphology and is recovered as sister to Sacoglottis in the topology; we recommend restoring Schistostemon to the rank of subgenus within Sacoglottis. A review of prior published reports of fossil fruits attributed to Humiriaceae led to the rejection and/or reattribution of some records but supports recognition of Vantanea, Humiria, Humiriastrum, and Sacoglottis. The available characters do not support recognition of mul...

TL;DR: It is found that eggs of almost all of the species discussed have a similar flange with glue on the periphery that may prevent the egg from becoming detached from the fruit as it matures and during eclosion of the first instar larva or protect eggs against mechanical injuries.
Abstract: In Venezuela Amblycerus crassipunctatus Ribeiro-Costa feeds in seeds of Vantanea minor Bentham, Humiriaceae, a new host family for the Bruchidae. Species of Amblycerus Thunberg now are known to feed in from 11 to 14 families of plants, more than any other bruchid genus. Ecological relationships of A. crassipunctatus with its host were compared to A. nigromarginatus (Motschulsky), A. luteonotatus (Pic), A. dispar (Sharp), A. guazumicola Kingsolver and Johnson, A. vitis (Schaeffer), A. acapulcensis Kingsolver, A. robiniae (Fabricius), A. hoffmanseggi (Gyllenhal), A. testaceus (Pic), A. submaculatus (Pic), A. cistelinus (Gyllenhal), A. longesuturalis (Pic), and A. schwarzi Kingsolver and their hosts. A. crassipunctatus damaged 28.5% to 39% of V. minor fruits examined. In other species of Amblycerus where these figures are available, from 01.0% to 61% of the fruits were damaged. We found that eggs of almost all of the species discussed have a similar flange with glue on the periphery. This kind of at...

TL;DR: The diversity of stamen structures in the family with consideration of dehiscence patterns and the evolutionary transitions between tetra- and disporangiate anthers is surveyed, and the significance of inter-generic variation in gland position and anther morphology within the family is discussed.
Abstract: Humiriaceae have had little recent comparative morphological study except for their distinctive fruits. We surveyed the diversity of stamen structures in the family with consideration of dehiscence patterns and the evolutionary transitions between tetra- and disporangiate anthers. Novel interpretations of floral morphology support new combinations (Duckesialiesneri K.Wurdack & C.E.Zartman, comb. nov. and Vantaneaspiritu-sancti K.Wurdack & C.E.Zartman, comb. nov.) for two species formerly in Humiriastrum. We investigated all eleven species of Sacoglottis for diagnostic features that may contribute to better species delimitations, and describe Sacoglottisperryi K.Wurdack & C.E.Zartman, sp. nov. as an endemic of the Pakaraima Mountains in western Guyana. Finally, our survey across Humiriaceae for extrafloral nectaries (EFNs) revealed their presence on leaves of all extant species as adaxial basilaminar and/or abaxial embedded glands, in addition to the frequent occurrence of marginal glandular setae. The significance of inter-generic variation in gland position and anther morphology within the family are discussed.

TL;DR: A new species of Humiriaceae, Vantanea maculicarpa, growing in French Guiana terra-firme forest is described and illustrated and a key to the species and the IUCN status Least Concern are proposed.
Abstract: A new species of Humiriaceae, Vantanea maculicarpa, growing in French Guiana terra-firme forest is described and illustrated. This new species is distinguished from all other species of Vantanea by fruits covered by white lenticels, a character so far unknown in this genus. It also presents a pubescent intrastaminal disk, a feature encountered in two other Vantanea species only: it is further distinguished from V. parviflora, the morphologically most similar species, by more stamens and from V. ovicarpa by a much smaller rough endocarp with five valves. A key to the species of French Guiana and the IUCN status Least Concern (LC) are proposed.
