Flowers of extant Quintinia are described in detail on the basis of field observations and serial microtome sections and compared with flowers of the Late Cretaceous Silvianthemum suecicum and Bertilanthus scanicus on the basis of new analyses of the fossil material. The analyses of both extant and fossil material also include synchrotron-based X-ray tomographic microscopy. The study shows that Quintinia and Silvianthemum/Bertilanthus have more features in common than previously recognized and strongly reinforces their earlier assumed close relationships. Among important characters linking the three genera are similar secretory hairs on the floral surface and pedicel; short sepals; free, quincuncial petals; broad anthers with small pollen sacs; 4-aperturate pollen (in Silvianthemum and Quintinia); postgenital union of the 3-4 apocarpous styles (in Silvianthemum and Quintinia); connection of the apocarpous carpel parts with the floral base; downward tapering ovary and locule(s); placentation on incomplete septa; and flask-shaped epidermal cells with a thin and long papilla on the carpels. Features observed in Quintinia, particularly the presence of bitegmic ovules and free petals, suggest that the apparent phylogenetic position with extant Paracryphiales (campanulids) needs further analysis. Bitegmic ovules are not known from other Paracryphiales or campanulids, and the presence of free petals is unusual in campanulids.

Based on herbarium collections, the Malesian species of the genus Lasianthus are revised. A total of 131 species including 5 subspecies and 6 varieties are recognized from the Malesian region, of which 41 species, 3 subspecies and 3 varieties are described as new, and 3 new combinations are made for varieties. 22 species names and 15 variety names are reduced to synonyms. Ten species names and 2 varieties are treated as dubious mainly because their types cannot be traced. Additionally, 11 species are further excluded from Lasianthus. All species are described and a key to Malesian Lasianthus is given. TAXONOMIC HISTORY Generic delimitationLasianthus Jack was established in 1823 based on two Sumatran species, Lasianthus cyanocarpus (later selected as the type of the genus; see below) and Lasianthus attenuatus. In the same year Blume (1823) listed several plant species under the genus name Mephitidia attributed to Reinwardt but described one species M. hexandra himself. The genus was redescribed two years later by Reinwardt (1825), but no species were mentioned by him. According to the International Code of Botanical Nomenclature (McNeill et al. 2006), the genus Mephitidia is attributed to Reinwardt ex Blume with M. hexandra Blume as type. Blume (1826Blume ( -1827 realized that Mephitidia was synonymous with Lasianthus Jack and provided accounts of the Javanese species. Mephitidia continued to be used by some authors because they were aware of an earlier publication of Lasianthus Adans. (= Gordonia) for a genus in the Theaceae. De Candolle (1830) was the most significant of these authors and Korthals (1851) was the last author to use Mephitidia for the Malesian species in taxonomic publications. Later, Lasianthus Jack has been conserved for the genus treated here. Blume (1823) described from Java a monotypic genus Lito santhes, which is closely related to Lasianthus. Inherently Ridley (1923a) reduced this genus to a section of Lasianthus, however Bakhuizen van den Brink (1965) retained Litosanthes as a separate genus based on three characters: imbricate corolla, forked stipules, and pedunculate inflorescences. Deb & Gangopadhyay (1991) transferred some Indian taxa to Litosan thes, but subsequently Gangopadhyay & Chakrabarty (1992) reduced these taxa of Litosanthes to a section of Lasianthus (see section below).The circumscription of Lasianthus Jack was more or less modified by later authors, especially referring to the number of ovary locules or pyrenes. In Jack's description Lasianthus has ovaries with 4 locules each with a single basal erect ovule, which normally develops into a drupe with 4 pyrenes. Blume (1826-1827) followed Jack's view, but described more variation based on more Malesian species: 4-9 locules and a drupe with 4-9 pyrenes. Wight (1846) modified the genus by adding a species with a 2-locular ovary and drupes with 2 pyrenes (L. foetens Wight = Saprosma foetens (Wight) K.Schum. (1891)). Korthals (1851) established a subgenus of Dysosmia based on a Javanese species Mephitidia dichotoma Ko...

“…Warburg (1900b) assumed that P. polycephalus would not be native to the Philippines and that individuals identified as such in the Philippines had actually been introduced, presumably from somewhere in Indonesia (then the Dutch East Indies, most likely from the Bogor Botanic Garden). Merrill (1904) identified two collections made by Copeland from Davao, Mindanao, as P. polycephalus. Martelli (1908), however, disagreed and regarded the specimens from Davao as "quite distinct" and to represent an undescribed species, P. brevispathus.…”
