Hypericum 67 References 119 Systematic index 121 The subdivision of the large sect. 9. Hypericum and four of its segregated sections having been treated in Part 4(1), Part 4(2) is concerned with those members of sect. 9, viz. Hypericum sensu stricto, in which the stem internodes have glandiferous raised lines – subsect. Hypericum series Hypericum . The series comprises 11 species and can be divided into (i) a group centred in Europe and the Mediterranean (4 species) and (ii) one centred in north-east Asia (6 species), one species of which is confined to western North America and another has spread westward into Europe. The remaining species ( H. perforatum ) is morphologically and geographically intermediate between two taxa, one from each group, and behaves as an allotetraploid hybrid. It is divided into four subspecies: subspp. perforatum , songaricum (Ledeb. ex Rchb.) N. Robson stat. nov. , veronense (Schrank) H. Lindb. and chinense N. Robson subsp. nov. The hybrids of H. perforatum are treated in detail and include H. × desetangsii nothosubsp. balcanicum N. Robson, nothosubsp. nov. ( H. maculatum subsp. immaculatum × perforatum ). Other new hybrids proposed are: H. × laschii nothoforma froelichii N. Robson, nothoforma nov. ( H. maculatum subsp. obtusiusculum × tetrapterum ), H. undulatum × tetrapterum and H. elegans × perforatum .","PeriodicalId":145329,"journal":{"name":"Bulletin of The Natural History Museum.

Three phenological phenomena were tracked: the opening and closing of flowers, flower production and fruit production. The large short-lived white flowers of S. lanceifolium , S. rudepannum , Lycianthes hypoleuca and L. gorgonea opened around sunrise and closed at sunset. The purple flowers of S. erythrotrichum and the small white flowers of S. nudum and S. cordovense opened more or less randomly. All seven study species flowered at least once during the months of May, June and July; there was substantial overlap in the flowering of some species. Four species, S. rudepannum , S. cordovense , S. lanceifolium and S. erythrotrichum , developed mature fruit during the monitoring period while the remaining species possessed immature fruit at the termination of the study. Thus, it appeared that these seven solanaceous species would provide a fairly constant supply of mature fruit during the rainy season. During observations of pollinators, 17 different bees in the families Colletidae, Halictidae and Apidae were found to visit the buzz-pollinated flowers of Solanum and Lycianthes . Analysis of the pollen loads revealed that bees were highly constant to Solanaceae although it was not possible to determine their constancy to particular species. Very few visits were observed to S. cordovense and L. gorgonea .","PeriodicalId":145329,"journal":{"name":"Bulletin of The Natural History Museum.
