No se deben confundir con los parafisos, cuyo origen es estrictamente receptacular
Para Roth (1977), o ovario inferior pode ter natureza apendicular e/ou receptacular
Os frutos sao derivados de flores epiginas, com ovario infero e hipanto de origem receptacular
Males are believed to mount the female shell and release their gametes, which are then swept into the female receptacular tract by the inhalant current produced by the female gill.
Males of Rhynchopelta concentrica McLean 1989 (Family Peltospiridae) lack a penis, but the presence of a large pallial vas deferens that acts as a prostate and the discovery of viable sperm within the female receptacular duct suggest that fertilization is likely to be internal.
La condicion receptacular
del acaecer no esta supeditada a ella misma.
Krause (1960), among others, considered the scales staminodes and the nectaries opposite these scales a disk (namely, receptacular outgrowth).
Although the scales arise relatively late in ontogeny and have occasionally been interpreted as receptacular emergences (e.
This requirement can be violated in cricket matings if, as often happens, the narrow spermatophoric tube is not threaded correctly into the female's receptacular
duct (Loher and Rence 1978); in such cases, the male fails to transfer any sperm regardless of the duration of spermatophore attachment (Sakaluk and Cade 1980, 1983).
For the Periplocoideae he described the swollen region below the filaments as the "basal tube" and interpreted it as corolline or receptacular (Kunze 1990: 38).
He stated as well that these results refute his hypothesis that the basal part of the "asclepiad filament tube is of receptacular origin" and that, consequently, the "basal tube in the Periplocaceae and the [basal part of the] filament-tube in the Asclepiadaceae are not homologous" (p.
This "transition apex" is distinguished from the vegetative apex by its larger size and broader shape but lacks apical derivatives such as involucral bract primordia, floral primordia, or receptacular
bract primordia (Popham, 1964; Popham & Chan, 1952).
