  • Description

    Species Description - Dioecious shrub 1-2 m tall, with tannish fissured bark, young branches subquadrangular with thick tomentum. Leaves sessile, blades lanceolate to elliptic, 5.5-10 x 1.5-4 cm, above lanose, below thickly lanose; apex acute, base connate-perfoliate, often au-riculate, margin crenulate to subentire. Inflorescence 15-30 cm long, with 1 order of branches; flowers sessile, borne on 5-15 pairs of pedunculate or subsessile heads in axils of progressively smaller leaves, each head 1-1.5 cm diam. with 20 or more flowers, peduncles to 2.5 cm long. Calyx tubular, densely lanate outside, tube 3-3.8 mm long, lobes 2-2.5 mm long, long acuminate. Corolla yellow, tubular, to subfun-nelform with thick tomentum outside, with warty hairs on inner surface in upper half of tube, tube 4.5-5 mm long, lobes oblong, 2-2.5 x 1.2-1.5 mm. Stamens sessile, inserted near sinus, anthers 0.7-1 mm. Ovary 1.5-2.5 mm long, thickly tomentose except at the base, style 3.5-4.5 mm long, stigma capitate, 0.5-0.7 mm long. Capsule narrowly ellipsoid, 6-7.5 x 2.5-3 mm, tomentulose on upper half, dehiscing septicidally, the valves acute. Seeds type 6, oblong, 0.7-0.9 x 0.2-0.3 mm, wingless, funicular end spongy, seed body 0.7 mm long.

  • Discussion

    Montes 4708 mentions that tender shoots are eaten by small rodents.

    The male flowers have slightly shorter corollas than the female ones. The style is especially long in female specimens of this species. In most neotropical Buddleja the stigma is close to the level of the anthers at anthesis but here the stigma is raised several mm above the anthers, which is the case in general for ser. Stachyoides. This character plus the seed coat type indicate a position in this series for this species. However, in general appearance it resembles B. blattaria (ser. Lanatae) of N Peru.
