Última Placentation patterns and seed number in fruits of South American Solanum subgen. Leptostemonum (Solanaceae) species Darwiniana Chiarini,Franco E.; Barboza,Gloria E.. Thirty-seven South American species representing seven sections of Solanum subgen. Leptostemonum were analyzed. Andromonoecious as well as hermaphrodite species were considered. The length and width of their fruits was measured, and the number of seeds per fruit was counted. Medial cross sections of fresh, ripe fruits were observed with a stereoscopic microscope and illustrated. Six placentation patterns and three types of seeds were described. A relationship among seed number, fruit size, fruit color and sexual system was detected by means of statistical analysis. These results suggest that andromonoecy affects fruit size and placentation patterns, in order to contain a higher number of seeds per fruit.

Ano: 2007 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0011-67932007000200002 Taxonomy of Hodgsonia (Cucurbitaceae), with a note on the ovules and seeds Naturalis Wilde, W.J.J.O. de; Duyfjes, B.E.E.. Hodgsonia, ranging from NE India through S China to Java and Borneo, was for a long time considered as monotypic, but there are two (and possibly three) species, demarcated at the Isthmus of Kra in S Thailand. The few, woody ‘seeds’ should be regarded as pyrenes, a condition not known elsewhere in the family Cucurbitaceae.

Ano: 2001 URL: http://www.repository.naturalis.nl/record/525962 The tribal placement of the monospecific tropical African genus Petitiocodon (Rubiaceae) based on molecular data and morphology Naturalis Tosh, J.; Block, P. De; Davis, A.P.; Dessein, S.; Robbrecht, E.; Smets, E.F.. A first phylogenetic placement of Petitiocodon based on molecular sequence data from three plastid regions (accD-psa1, rpl16 and trnL-F) is presented, in conjunction with a reassessment of morphology for the genus. Our results do not support an evolutionary affinity between Petitiocodon and Tricalysia (Coffeeae) as suggested by previous studies, but they confirm other research that Petitiocodon and Didymosalpinx are distinct genera. Placement of Petitiocodon in tribe Octotropideae is well-supported on the basis of molecular data and floral and carpological characters.
