A new species and a new combination in friesodielsia ( annonaceae ) of borneo
TL;DR: A new species of Friesodielsia (Annonaceae) is described from Borneo as mentioned in this paper, which is a large woody climber of lowland forests, the species has been collected from Sabah, Sarawak and Kalimantan.
Abstract: A new species of Friesodielsia (Annonaceae), Friesodielsia formosa, is described from Borneo. A large woody climber of lowland forests, the species has been collected from Sabah, Sarawak and Kalimantan. A new combination in Friesodielsia is made for Oxymitra grandifolia Merr. which is resurrected from the synonymy of Friesodielsia latifolia (Hook.f. & Thomson) Steenis. The name Oxymitra grandifolia is lectotypified.

TL;DR: The phenetic analysis of both morphological and molecular attributes clarified the segregation of genus Avicennia as a distinct identity away from Acanthaceae and indicated that the used morphologically and ISSR criteria is likely to be useful and valuable taxonomic traits.
Abstract: Acanthaceae has received considerable taxonomic attention at the familial, subfamilial, tribal and subtribal levels. Several different infra-familial classifications have been proposed for the Acanthaceae, but no taxonomic consensus has yet been reached. The main objective of the present study is to throw light on the phenetic relationships and to explore the contribution of morphological and molecular characters in systematics of Acanthaceae. The morphological data viz. macromorphology, stomatography, lamina architecture and ISSR profiles of 30 Egyptian acanthaceous taxa were investigated. The phenetic analysis using NTSYS-PC version 2.02 software based on 55 potentially informative morphological and molecular characters indicated that the used morphological and ISSR criteria is likely to be useful and valuable taxonomic traits. The morphological characters and ISSR aspects of all the studied species produced a phenogram that showed two series; one of them had two subseries, the first one comprised only three taxa while the second divided into two clusters, each contained two groups. The delimitation and the membership of the studied taxa clearly merit additional study using more criteria. The phenetic analysis of both morphological and molecular attributes clarified the segregation of genus Avicennia as a distinct identity away from Acanthaceae. Acanthus mollis & A. montanus are isolated in its own series that comparable to tribe Acantheae of the current taxonomic systems. The studied species of Thunbergia are gathered its own subseries that comparable to tribe Thunbergiae and Ruellia in its own group that comparable to tribe Ruellieae.

TL;DR: The first volume of the Flora of India is due to the completion of the first volume as mentioned in this paper, which is an event of no small importance in descriptive botany and is the last of our possessions whose vegetable wealth botanists have undertaken to describe in a systematic order.
Abstract: AbstractTHE completion of the first volume of the Flora of India is an event of no small importance in descriptive botany. That India should be almost the last of our possessions whose vegetable wealth botanists have undertaken to describe in a systematic order, is due to various causes, not the least of which is the enormous labour of collecting and sifting the scattered literature bearing on this subject. The books and short papers on the botany of various parts of India are exceedingly numerous, and several works have been commenced never to be completed. Dr. Hooker himself, in conjunction with Dr. T. Thomson, published some years ago the first volume of a Flora of India based upon a more elaborate plan than that of the work now in progress, which departs from that of the other Colonial Floras, Hooker's “Student's Flora of the British Islands” having served as a model.The Flora of British India.

TL;DR: In both groups, long-distance dispersal appears to have played a more significant role in establishing modern patterns than had previously been assumed.
Abstract: Annonaceae are a pantropically distributed family found predominantly in rainforests, so they are megathermal taxa, whereas Rhamnaceae are a cosmopolitan family that tend to be found in xeric regions and may be classified as mesothermal. Phylogenetic analyses of these families are presented based on rbcL and trnL-F plastid DNA sequences. Likelihood ratio tests revealed rate heterogeneity in both phylogenetic trees and they were therefore made ultrametric using non-parametric rate smoothing and penalized likelihood. Divergence times were then estimated using fossil calibration points. The historical biogeography of these families that are species rich in different biomes is discussed and compared with other published reconstructions. Rhamnaceae and most lineages within Annonaceae are too young to have had their distribution patterns influenced by break-up of previously connected Gondwanan landmasses. Contrasts in the degree of geographical structure between these two families may be explained by differences in age and dispersal capability. In both groups, long-distance dispersal appears to have played a more significant role in establishing modern patterns than had previously been assumed. Both families also contain examples of recent diversification of species-rich lineages. An understanding of the processes responsible for shaping the distribution patterns of these families has contributed to our understanding of the historical assembly of the biomes that they occupy.

Abstract: In 19491 pointed attention to the fact that the annonaceous generic name Oxymitra (Bl.) Hook. f. & Th., Fl. Ind. (1855) 145, is a later homonym of the ricciaceous genus Oxymitra Bischoff ex Lindenb., Syn. Hepat. Eur. (1829) 124. Cf. Bull. Bot. Gard. Buitenzorg ser. III, 17: 458.
As the name of the hepatic genus is still in use it seemed to me impossible to suppress it and consequently I proposed a new generic name for the annonaceous genus, viz. Friesodielsia, without making any new combinations under that name.
