Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1912 edition. Excerpt: ...floral detailsa, Petal (auriculate); b, staminodes; c, stamens; d, filament; e, pistil. Scale 3. Pedicels glabrous. Corolla 3.5 to 4 mm. long. Anthers slightly apiculate. Staminodes hardly above 1 mm. long. Seeds ovoid (pi. 96, c); umbilical area circular; glabella distinctly biscutellate. Leaves long-petiolate, pouchless.--Porto Rico (Sintenis 5001, 3950; Heller 507); Florida (Garber; Chapman 11, Curtiss 1759).

It is, however, safe to admit that the Porto Rico and Florida specimens represent the original S. mastichodendron of Jacquin and Gaertner (fig. 84), even though Jacquin does not mention the characteristic "glabella ovata bipartita" which seems to be a constant feature of the seeds in the Porto Rican and Floridan specimens and which is clearly shown in plate 202 of the Supplementum Carpologiaea of the last author. An obscure detail of this question is that the origin of the specimen made use of in Gaertner's description is not given, while the names acouma jaune ou abricot des bois would seem to indicate a product of the French West Indies. The other forms may represent entirely new species, or correspond to some of the older ones (S. obovatum Gaertn., S. acouma A. DC, S. foetidissimum Jacq.) (fig. 85). In regard to their status, we may repeat here what Jacquin said with respect to the whole genus: "Donee omnium fructificatio plene cognita sit, frustra tentabimus." Only the careful comparison of large series of complete materials will enable us to decide, and meanwhile Urban's step in condensing forms a few of which are to all appearances specifically characterized must be...show more
