Ovary summit without hairs (8th, 13th photos)
Petal length (mm): 18,17,19, 17 (2nd photo), 17.5 (3rd photo), 19 (4th photo), 19 (5th photo)
Sepals were spreading for well-opened flowers; they were not strongly reflexed, nor were they pressed against the hypanthium (e.g., 9th, 10th, 11th photos)
Number of flowers in inflorescence: 5,5,7,8,8,10
Inflorescence length from the base of the lowest pedicel to the base of the highest flower (mm): 53,48,50
Lowest pedicel length (mm): 22,25,30, 26 (15th photo; the measured pedicel shown with yellow arrow).
Lowest pedicels were not subtended by a leaf in 6 of 10 inflorescences examined (e.g., 12th, 13th photos); the remaining 4 inflorescences had lowest pedicels that were subtended by a leaf (e.g., 14th photo; the subtending leaf shown with yellow arrow).
Leaves slightly hairy adaxially (top surface) at flowering and were glabrous abaxially (on the underside). See 16th and 17th photo.

Willows (Genus Salix)Observer
rbolesDescription
Same shrub as observed one week earlier (the “no dog” sign in the background of the last photo was captured in both observations): https://www.inaturalist.org/observations/207304203
One week later, more (most) flowers have reached anthesis, but there are still some that have not matured.
Anther length estimated as: 1.1-1.2 mm (4th photo); 1.0 mm (5th photo).
Two flowers were removed from a catkin and photographed through the lens of a dissecting scope (second last photo). Elongated green nectar glands are visible protruding from the base of the flower.
Additional notes: Photos 2 and 4 were taken with a Canon Powershot camera and the remainder were taken with a cell phone. Photos 7 and 8 were taken through the lens of a dissecting scope.
