B. xanthina 'Atrorubens'

A hybrid bred by Inspector Bouché with B. rubrovenia. It is much closer to the latter form in terms of leaf shape, but again, the leaf color is much closer. The plant is generally smaller and also seems, similar to B. xanthina, to grow somewhat taller, i.e., to develop more distinct stems. The surface of the elongated, cirri-lanceolate leaves has an almost blackish-green, but always somewhat metallic-sheened color on the surface, while the underside appears brownish-red. The auricles at the base are as small as they occur anywhere else in B. rubrovenia Only a few bristles are found on the surface veins, but there are many more on those of the underside, which are also soft-baseed in the cone. This is usually also the case with the leaf stalk, but to a much lesser extent with the flower stalk. The latter often shows no trace of hairs at all. The reddish, almost non-fleshy, and lanceolate stipules are indicative of \*B. rubrovenia\*.
