Download or read book Seed Micromorphology of Neotropical Begonias written by Anton De Lange and published by . This book was released on 1999 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seeds of about 235 Neotropical Begonia species, representing almost all recognized American Begonia sections, were studied using scanning electron microscopy. The seeds show an appreciable diversity in size, shape, and micromorphology, which is helpful in the delimitation of sections and sometimes also of species. Mean seed length varies from 235 m in Begonia filipes to 1450 m in B. fruticosa; most seeds have a length between 300 m and 600 m. The shape of the seeds varies from almost globular to narrowly elliptic, and the length to width ratio ranges from 1.2 in B. hexandra to 8.1 in B. fruticosa. Further differences exist in the shape of the testal cells, the undulation of the anticlinal walls, the bulging of the outer periclinal walls, and the pattern and roughness of the cuticle. Five of the 15 mainly Brazilian, five of the 12 Andean and Guianan, and one of the eight middle American sections have a seed structure that is characteristic at the sectional level. All these sections have a relatively restricted geographical distribution, and they may differ in growth form or habitat. Most species of the other sections, including the larger and more widely distributed sections Begonia, Gireoudia, and Knesebeckia, have seeds conforming to the ordinary seed type. In a number of the sections, the structural differences of the seeds are nicely correlated with differences in growth form and/or in means of dispersal. In contrast to the African begonias, the great majority of the Neotropical begonias have anemoballistic dispersal. Seeds may be adapted to wind dispersal by extended micropylar and/or chalazal ends with inflated, air-filled cells, such as in the Brazilian sections Solananthera, Trendelenburgia, and Enita and in the Andean section Rossmannia, or by a more pronounced surface with deep, collapsed testal cells, such as in sections Gobenia and Scheidweileria. Zooballistic dispersal by passing animals is supposed to be present in section Casparya. The seeds of sections Casparya and Trachelocarpus have very pronounced cuticular patterns and may be secondarily dispersed by rain wash or by adhering to animals. No distinct indications for an intercontinental relationship between Neotropical, African, and Asiatic sections could be established.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Studies in the Begoniaceae The preparation of this paper was prompted by the need for more knowledge of both the taxonomic history of the group and of the floral morphology of the members of the genus Begonia. As a material for the study, the flowers of the species currently available in greenhouses in the Boston area have been used. When selecting these species, all garden varieties and hybrids were excluded and twenty-three species noteworthy for their rareness were studied. Most of those species are from the Neotropical region (brazil lo, Mexico 3, the Americas 1, Argentina l, Bolivia 1, Colombia 1) and the remainder from the Paleotropical region (india 2, indo-china l, Sumatra 2, Tropical Africa All these plants occur in wild condition in the aforementioned regions.
