ABSTRACT
The young prothallus of Polypodium lepidotrichum (F�e) Maxon is a short filament with four to five cells. Later on, the thallus is spathulate. The mature thallus, about eight weeks after germination, is cordate, reniform or ovate with a narrow base. Bisexual and unisexual gametophytes were produced. sporophytes were observed twelve weeks after the spore were sown. It is concluded that the reproductive strategies of P. lepidotrichum include intragametophytic intergametophytic fertilization.

    Rhizanthes lowii (Beccari) Harms (Rafflesia- ceae) is a parasitic plant that grows in the understory of the rainforest in South-East Asia. This plant does not have leaves, stems, or photosynthetic tissue and is characterised by the emission of a strong odour that attracts the natural...

    Plant reproductive success within a patch may depend on plant aggregation through pollinator attraction. For rewardless plants that lack rewards for pollinators, reproductive success may rely strongly on the learning abilities of pollinators. These abilities depend on relative co-flowering...

    We examined the reproductive biology of Melocactus curvispinus Pfeiffer (Cereeae, Cactoideae) in xeric areas of northern Venezuela. Floral traits correspond to a classic hummingbird-pollination syndrome; however, pollination is shared between hummingbirds, Leucippus fallax (Bourcier 1843), and...
