Why do flowers in Namaqualand close? : Flower closure in relation to the environment and pollen sensitivity to moisture by Von Hase, Amrei

“…Flowering coincides with the wet season which imposes constraints on pollination success. The wide-spread phenomenon of flower closure in the flora may represent an adaptation for protecting sensitive pollen from damage by moisture (dew, rain). …”

Life history traits of South African Encephalartos spp. (Zamiaceae) and their implications for understanding population structure, responses to threats and effective conservation a... by Konings, Kim Martina

“…The groups were not found to correspond with the most recent phylogeny for Encephalartos and thus phylogenetic constraints were excluded. An analysis of environmental variables for 193 populations of species in all groups, including maximum and minimum temperatures, mean annual precipitation, moisture index, rainfall co-efficient of variation and fire return frequency, showed that the means per group were not significantly different from each other for most of the variables. …”
