Are The Fruiting And Non-Fruiting Acrocarpous Moss Barbula indica (Hooker) Sprengel in Nigeria Distinct Species?
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2018, Vol 13, Issue 1
Abstract
Barbula indica (Pottiaceae), a dioecious acrocarpous moss had never been found with sporophytes in Nigeria. The occurrence of fruiting B. indica from two populations in the Nigerian forest and derived savanna is reported for the first time. Aspects of the morphological characters of fruiting and non-fruiting plants were compared to ascertain if they are distinct species or not. The leaf and costa length were not significantly different in both types of plants. The ratios mean leaf length : mean leaf width, costa length : leaf length and apical cell size were higher in non-fruiting than in fruiting shoots. However basal and median cell lengths were higher in fruiting than non-fruiting samples. Mean shoot lengths in fruiting plants were 8.8 + 2.946 mm and 9.6 + 2.330 mm in non-fruiting samples. Non-fruiting shoots produced more axillary gemmae than fruiting ones. As all of these vegetative differences are within the morphological range of Barbula indica the fruiting and non-fruiting shoots are not distinct species.
