Seite 271 - I consider the pistillum or female organ of all phanerogamous plants to be formed on the same plan, of which a polyspermous legumen or folliculus whose seeds are disposed in a double series may be taken as the type. A circular series of these pistilla, disposed round an imaginary axis, and whose number corresponds with that of the parts of the calyx or corolla, enters into my notion of a flower complete in all its parts.
Seite 311 - Goodenoviae, in the greater part of whose genera the ovarium has actually two cells with one or an indefinite number of ovula in each ; while in a few genera of the same order, as Dampiera, Diaspasis, and certain species of Scaevola, it is equally reduced to one cell and a single ovulum.
Seite 560 - In the prosecution of this task his public engagements, and other important scientific inquiries accumulating in a degree beyond what was expected when he commenced the work, it was agreed between Mr. Brown and myself that the original plan should be modified, and that the assistance of a coadjutor should be obtained. " On this point I have the satisfaction to state that Л.
Seite 209 - I have added specific characters of the only two specie* with which I am acquainted ; but Hoya carnosa probably includes several species, which can only be determined from living specimens : it is also to be considered as the type of the genus, Hoya viridiflora differing in some degree in the structure of its corona, and considerably in habit.
Seite 19 - I am inclined to think, not only from its consideration in this family, but in many others, that it may be consulted with advantage in fixing our notions of the limits of genera : and though its minuteness may perhaps always exclude it from a place in generic characters, yet it well deserves, to use the words of Linnaeus when speaking of habit, to be "occulte consulendus.
Seite 363 - Willdenow, a genus which he had many years since investigated without being able to determine its place in the natural system. Examination proved these two plants to be so nearly akin, that they might perhaps be included in the same genus. They are here, however, separated, and the two genera are considered as forming a family distinct from all those at present known. The place of this new family (LIMNANTHES) is not absolutely determined ; but it is suggested that in two remarkable points of its...
Seite 10 - This observation originated with Mr. Dryander; and the few exceptions hitherto known to it, occur considerably within the tropic. The fact is the more deserving of notice, as their diffusion is very extensive in the southern hemisphere, not merely in latitude and longitude, but also in elevation ; for they are not only found to exist in all the great southern continents, but seem to be generally, though very unequally, spread over their different regions : they have been observed also in the larger...
Seite 716 - Pandanea, we are hereby enabled to connect our fossil fruit with this remarkable tribe of plants, as a new. genus, Podocarya. I owe the suggestion of this name, and much of my information on this subject, to the kindness of my friend, Mr. Robert Brown. \ The large spherical fruit of Pandanus, hanging on its parent tree is represented at PI. 63, Fig. 1. Fig. 11 is the summit of one of the many Drupes into which this fruit is usually divided. Each cell when not...
Seite 548 - ... take place, or the relations of the reduced series to the other parts of the flower, have, as far as I know, never yet been particularly attended to. It will probably appear singular, that the observation of these relations in the reduced series of pistilla should have suggested the opinion, that in a complete flower, whose parts are definite, the number of stamina and also of pistilla is equal to that of the divisions of the calyx and corolla united in Dicotyledones, and of both series of the...
Seite 686 - C. cuneifolia) has since been found during an expedition into the interior of the above country, growing on the banks of the river Lachlan, in 1817, by Mr. Allan Cunningham, who is commended by Mr. Brown as 'an indefatigable collector and acute observer'.
