bjpt-26071	Naderifar, Maryam; Sonboli, Ali; Gholipour, Abbas	Pollen morphology of Iranian Dracocephalum L. (Lamiaceae) and its taxonomic significance	2015	12	.pdf	application/pdf	3299	238	56	Based on pollen data, D. oligadenium shows diagnostic features compared to D. kotschyi such as: smaller polar axis (38.8 µm vs 43.7 µm), colpus length (30.5 µm vs 38.1 µm), exine thickness (1.1 µm vs 0.8 µm), mesocolpium diameter (8.5 µm vs 11.1 µm) and apocolpium index (0.15 vs 0.14), which are useful for separating it from D. kotschyi. Considering the results obtained here from palynological data along with diagnostic morphological characters we may propose that D. oligadenium is a distinct species from D. kotschyi and could be resurrected as a separate taxon.	cache/bjpt-26071.pdf	txt/bjpt-26071.txt
