Female catkins were both green and brown at time of harvest. Little to no fall color at time of seed collection (4 Sept. 2015) with approximately 75% of leaves already dropped. During growout in 2016, samples #699-3 and #699-5 resulted in seedlings that have petiolules (on small seedlings) that average 3-5 mm in length with the leaf apex being rather sharply acute, possibly indicating presence of hybrids. Other samples (#699-1, #699-2, #699-6, and #699-7) seem to exhibit characteristics of B. pumila with densely pubescent leaves and stems, with leaves having the apex usually broadly acute or obtuse to rounded, and essentially leaves being sessile or less than 1mm in length. | 1927397 | Ames 32955 |
