TitleThe distally lobed inner integument of Hernandia peltata Meissn. in DC. (Hernandiaceae)
JournalBlumea - Biodiversity, Evolution and Biogeography of Plants
AbstractA peculiar structural detail, occurring during the development of ovules, seems to have passed almost unnoticed till the present day. It concerns the distal rim of either the outer or the inner integument, which appears to be slightly lobed in the ovules of several unrelated plants. In a recent note (1970) I called attention to this feature.
It is known from Juglans and Platycaria (Warming, 1878; Leroy, 1955; Boesewinkel and Bouman, 1967), where the single integument is two-lobed. Warming mentioned two more cases, namely Lagarosiphon and Symplocarpus; however, I cannot confirm his observations from dried material. I noticed it myself in Scyphostegia horneensis, in Caloncoba welwitschii, and in Sterculia alexandri. In these three species the lobes occur at the rim of the outer integument. To these can now be added Hernandia peltata. However, in that species the lobes occur at the rim of the inner integument.
