Malus toringoides (Rehd.) Hughes, 1920, is shown to be the same as Pyrus bhutanica W.W. Smith, 1911, therefore requiring a new name, Malus bhutanica, which is hereby provided.

This paper continues the systematic treatment of the bamboos of Nepal and Bhutan, covering four hardy temperate genera with semelauctant inflorescences and 3 stamens from the subtribe Arundinariinae Bentham. Arundinaria Michaux has leptomorph rhizomes, while Thamnocalamus Munro, Yushania Keng f., and the new genus Borinda have pachymorph rhizomes. The separation of these and related Sino-Himalayan genera is discussed. Sinarundinaria Nakai is treated as a synonym of Fargesia Franchet, a genus that is not known from the Himalayas. A new treatment of Himalayan Thamnocalamus species is given, including the description of two new subspecies of Thamnocalamus spathiflorus (Trin.) Munro, subsp. nepalensis and subsp. occidentalis, and one new variety, bhutanensis. T. aristalus is treated as a synonym of T. spathiflorus subsp. spathiflorus, and Fargesia crassinoda Yi is transferred and given new status as Thamnocalamus spathiflorus (Trin.) Munro var. crassinodus (Yi) Stapleton. Two new species of Borinda are described: B. chigar from West Nepal and B. emeryi from East Nepal. Six species of Fargesia from Tibet are transferred to Borinda, which thus comprises eight species.

During the 1830s Walker Amott sent a collection of Asian Acanthaceae to be identified by Nees von Esenbeck in Breslau. This material was used by Nees as the basis for describing one genus and 22 new species in Hooker's Companion to the Botanical Magazine in 1836. Both the publication and the collection were subsequently forgotten. During the course of work on the Flora of Ceylon the types were rediscovered in the general herbarium at Edinburgh. The present paper links Nees’ names with the types in Edinburgh, lectotypifying where appropriate and commenting on the taxonomic status of each species.

Reproductive structure is considered in the context of process morphology: the significance of homoeotic transformations is commented on in Araceae and other modern angiosperms. Disruption leads to the rearrangement of processes and destabilization of process combinations, or decanalization. This is apparently more readily achieved in certain extant angiosperms than in others; both environmentally triggered decanalization, including galling, and genetically prompted decanalization are discussed and illustrated with examples including those leading to the expression of ‘lost’ features. This is extended to a consideration of ‘character’ comparisons in extant angiosperms and possible pitfalls there. Finally, this approach is applied to the relationship of certain extant groups of seed-plants and their fossil allies and it is concluded that modem ones are (distantly) interrelated relics of a complex of ‘hemiangiosperms’ of the Triassic.
