, calyx) have a relatively sparse covering of capitate-stalked glandular trichomes.
Inflorescences produced before leaves, subtended by small bracts on reduced cymes with 2-5 flowers per cluster, flowers rarely solitary; peduncles stout, 2-3 mm long, pedicels slender, <2 mm long, with a basal small and caducous bracteole
<1 mm, soon deciduous.
The pistillate flowers are clustered in cyme-like inflorescences that consist of three flowers, three laciniate tepals and one short, lanceolate, pilose, yellow-greenish bracteole
(see Figure 1E).
The following characteristics were used: bracteole
form, vegetation habit, standard color, wings color, string bean color, string bean transversal section, string bean bending, string bean suture, string bean color at the physiological maturation, wall of the string bean staple fibers, string bean standard tegument, seeds tegument darker color, seeds brightness, seeds form, hypocotyls pigmentation, emergent cotyledon color, color tonality from the chlorophyll leaf, anthocyanin in the leaf, leaf form, leaves persistence, lodging, floral size, bracteoles
button size, bracteole
/chalice length relation, chalice/bracteole
color, wings opening, stiletto/keel relation, string bean position in the plant, string bean apex position and dry string bean color and seeds ribbing.
Typical microscopic characters of powdered hop cones include numerous large yellow glands unique to the species (lupulin glands), abundant bracteole
and leaf fragments, as well as sparsely distributed glandular and many covering trichomes (Jackson and Snowden, 1968; Neve, 1991; Yamada et al.

Townsend, the partial florescence consists of a solitary hermaphrodite flower and a solitary small sterile flower formed by a large-celled, spongy, ventrally floccose cylinder tipped with small greenish processes present within and scarcely exceeding one bracteole

empty (Townsend, 1993).
number, however, is rather homoplasious (Fig.
For measurement of leaf, pod, and bracteole
characteristics, a central leaflet from a fully developed trifoliate leaf, hilly open flowers, and fully developed pods were used, respectively (Singh et al.
