STUDIES IN THE SOUTHERN AFRICAN SPECIES OF JUSTICIA AND SIPHONOGLOSSA (ACANTHACEAE): SEEDS

The seeds of all species of Justicia (except J.thymifolia (Nees) C.B.Cl.) and Siphonoglossa in the southern African region (as defined by the Flora of southern Africa) were examined with the Scanning Electron Microscope.A wide range of different seed surfaces were seen, many of which could be correlated with other Alocasia characters to further rei

In fire-dependent forests, managers are interested in predicting the consequences of prescribed burning on postfire tree mortality.We examined the effects of prescribed fire on tree mortality in Florida Keys pine forests, using a factorial design with understory type, season, and year of burn as factors.We also used logistic regression to model the
