Abstract: Buddleja crispa Benth. is an important species growing on high altitudinal sites of Jammu province. Presently, two populations from Pouni and Batote of Jammu province were analysed for morphological, phenological and meiotic aspects. The plants of this species remain in vegetative stage from late September to mid-February, form buds from mid-February to early March, show full blooming from early March to mid-May and fruiting from May to June. Morphological comparison using one way ANOVA reveals Batote population is vigorous in comparison of Pouni population which seems to be an outcome of prevailing climatic conditions. Meiotic studies revealed all PMCs having diploid count of 38. These chromosomes paired as 19 bivalents at diakinesis and metaphase I and separated equally (19:19) at anaphase I. The second meiotic division was also regular. The percentage pollen stainability and viability as determined using 1% acetocarmine, triphenyl tetrazolium chloride (TTC) and fluorescein diacetate (FDA) respectively valued as 88.65%, 53.82% and 62.6% which points towards cytological stability of the species.
