Description
Species Description - Amply foliate, arborescent shrubs attaining 1- 4(-5) m, armed on internodes and on some lf- stks with straight declined aculei 1—4.5 mm, or the lf-stks with recurved cat’s-claw ones, except for sometimes facially glabrous lfts minutely and often densely puberulent overall and livid-granular, the lfts strikingly bicolored, thin-textured, when dry dark green or dark brown above, pallid beneath, the inflorescence a leafy-bracteate or sometimes distally efoliate pseudoraceme of oblong-ellipsoid, spiciform (subracemose), cylindric, or even amentiform capitula. Stipules lanceolate, linear-setiform or -oblong 2-8 mm, 1- 2-nerved, often lanulose externally, becoming papery. Leaf-formula (ii—)iii—vi(—ix)/6—12, the lf-stks 3—12(—16) cm, the ventral groove bridged between pinna-pairs and there with a spicule 0.6-3 mm; rachis of longer pinnae (l-)2-6.5(-7) cm; lfts oblong or ovate-elliptic (the distal pair sometimes obovate), usually obtuse-mucronulate but sometimes apiculate, the larger ones 6.5-15 x 3-6 mm, 2-3(-3.7) times as long as wide, all slenderly 3—4-nerved dorsally, the midrib displaced to divide blade ±1:2, the inner posterior nerve brochidodrome well above mid-blade. Peduncles 1-4 per node, 1-3.5 cm; spikes relatively loose or early becoming so, without filaments 6.5-7.5 mm diam., the axis at full anthesis commonly 8-20 mm, exceptionally (in Sinaloa) to 6 cm, the pyriform fl-buds densely puberulent or silky-pilosulous, much longer than the small caducous bracts; pedicels 0-0.4 mm; flowers 5-merous 10-androus, all or almost all bisexual; calyx membranous campanulate 1.2-2.1 mm, the often unequal, deltate or depressed-deltate teeth 0.2-0.5 mm; corolla pinkish, narrowly vaseshaped 2.6-3.7 mm, the lobes shorter than tube, erect or in age arched outward; filaments whitish or pale pink, monadelphous through 0.2-0.5 mm below the puberulent ovary, exserted 5-7 mm. Pods to 10 per capitulum, in profile undulately linear, straight or gently decurved, when well fertilized 40-60 x 6-9 mm, 5-8-seeded, contracted at base into a stipelike neck ±3 mm, cuspidate at apex, the replum armed either distantly randomly or all around with gently recurved aculei 0.5-2 mm, the replum and valves alike densely puberulent and livid-granular overall, the papery valves low-bullate over the basipetal seeds, when ripe breaking up into free-falling, individually dehiscent articles ± 6-8 mm long.
Distribution and Ecology - In pine-oak and tropical montane deciduous woodland, 1460-2400 m, discontinuously widespread in w. and s. Mexico, from Sinaloa (Sa. Surutato) to Jalisco, e. and s.-e. to centr. Veracruz, Oaxaca, and Chiapas. —Fl. (V-)VI-XI (-XII).
