Revision of Schradera (Rubiaceae-Schradereae) in Malesia Naturalis
Puff, C.; Greimler, J.; Buchner, R..
A taxonomic revision of the Asiatic taxa of Schradera Vahl (formerly known as Lucinaea DC.) is presented. 16 species are recognized. Two new species (S. grandiflora, S. pseudonervulosa) are described from Borneo. The new name S. elmeri is published for the Philippine endemic previously known as Lucinaea involucrata. Two new subspecies are recognized in S. korthalsiana (subsp. korthalsiana and subsp. robusta) and three in S. membranacea (subsp. membranacea, subsp. flagellarioides, and subsp. parvifolia comb. & stat. nov.).

Puff, C.; Buchner, R.; Greimler, J..
A taxonomic revision of Lecananthus Jack, a genus of three species occurring in Sumatra, the Peninsular Malaysia, and Borneo, is presented. A new species, L. peduncularis Puff, endemic to Sarawak, is described, and a new combination, L. pentander (Merr.) Puff (syn. Lucinaea pentandra Merr.), is published.

Lecananthus and Leucocodon, two genera to be added to the tribe Schradereae (Rubiaceae) Naturalis
Puff, C.; Buchner, R..
The presence of a combination of various character states (epiphytic habit, adventitious rootlets in rows along the internodes; capitate, involucrate inflorescences; certain floral features such as ‘hooded’ corolla lobe apices; heterodistyly; fruit and seed morphology and anatomy; leaf anatomy) provides evidence that the monospecific Sri Lankan endemic Leucocodon and the small Malesian genus Lecananthus are to be added to the Schradereae, a tribe hitherto thought to be monogeneric.

The genera Mitchella and Damnacanthus. Evidence for their close alliance; comments on the campylotropy in the Rubiaceae and the circumscription of the Morindeae Naturalis
Robbrecht, E.; Puff, C.; Igersheim, A..
The two species of Mitchella (Southeast Asian and North American) and several species of the Southeast Asian genus Damnacanthus are investigated. Vegetative character states (growth form, branching pattern, leaves) of the two genera are described and compared. Damnacanthus always exhibits heterophylly and some species have paired thorns. The latter are interpreted as paired lateral shoots in the proximal part of a sympodial branch unit, and it is speculated that the paired thorns may be modified inflorescence shoots. Detailed information is also given on inflorescence structure and floral morphological and anatomical details of Damnacanthus and Mitchella. Particular emphasis is placed on the ovaries, the structure of which is remarkably similar in the two...
