300 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [VOL. 35 Fig. 24. Senna koelziana I. & B. Leaf + raceme xVi; petiolar gland x4; one abaxial petal + detached stamens and staminode x3 (McVaugh & Koelz 1163). Brandt 2383 (MEXU) in which the racemes are normally pedunculate in distal leaf-axils. The handsome foliage and sumptuous flowers of S. koelziana recommend it for trial in frostless gardens that can furnish conditions suitable for a Mediterranean flora.
1982] CASSIINAE—SENNA 301 93. Senna talpana Irwin & Barneby, sp. nov., flore deficiente affinitatis inscru- tabiUs, sed ex similibus speciebus mexicanis notularum harum coitu extricanda: fohola ampla penninervia 4-5-juga ±5.5-7 x 2.5-3 cm usque; stylus filiformis ±11 mm; legumen plano-compressum ±8-9 X 0.7 cm, 16-20-spermum.—MEXICO. Jahsco: barranca in steep mountains 11-12 miles s. of Talpa de AUende in headwaters of a w. branch of Rio Talpa, ±1650 m, 23-25.XI.1960 (fr jun), Rogers McVaugh 21334.—Holotypus, MICH; isotypus, NY. Amply leafy shrubs at anthesis ±2 m with terete striate green annotinous branchlets, appearing glabrous but the lf-stalks and axes of inflorescence in curved-puberulent and the thin-textured subciholate lfts thinly or remotely strigulose on both faces with straight appressed hairs up to 0.5-0.8 mm, the foliage strongly bicolored, dull dark green above, palUd-glaucescent beneath, the axillary racemes much surpassed by their subtending If, all lateral to leafy stems. Stipules caducous, not seen. Lvs 14-26 cm; petiole including discolored, when dry shrunken pulvinus 4-8.5 cm, at middle 1-2 mm diam, rounded dorsally, shallowly openly sulcate ventrally; rachis 7.5-11 cm, the longest interfoholar segment 25-32 mm; petiolar glands (much eaten) between all but the distal pair of lfts stipitate, in profile 1.3-2.7 mm taU, the slenderly ovoid-ellipsoid acute body ±0.4-0.7 mm diam; pulvinules 2.5-3 mm; lfts 4-5 pairs, moderately accrescent distally, in outhne obovate-elliptic obtuse but obscurely apiculate, the distal pair 5.5-7 x 2.5-3 cm, 2.1-2.4 times as long as wide, at base subsymmetrically cuneate, the margin plane, the slender midrib and 7-8 pairs of filiform camptodrome secondary veins prominulous be neath only, tertiary venulation scarcely perceptible. Racemes shortly (7-)10-22-fld, the axis together with slender peduncle 6-11 cm; bracts deciduous, not seen; fruiting pedicels 13-19 mm; perianth not seen; ovary puberulent; style filiform, persistent on young pod, ± 11 mm; ovules 16-20. Pod variably spreading-ascending, the stipe 1-1.5 mm, the (immature but almost fully formed) body Unear piano-compressed ±8-9 x 0.7 cm, bicarinate by the gently undulate sutures, the stiffly papery valves brown glabrescent veinless, shghtly raised over each forming seed, the seed-locules 4.5-5 mm long, as wide as the pod's cavity, the septa between them very narrow or almost 0; seeds not seen ripe, but evidently oriented with broader faces to the valves and bearing an areole on each.—Collection: 1. Openings in forest of oaks, Carpinus, Distylium, Magnolia and Podocarpus, ± 1650 m, locaUy abundant in the barranca of a w. source of Rio de Talpa, mun. Talpa de AUende, far w. JaUsco, Mexico; known only from the type-locality.— Fl. ±X. Because sound classification of Senna requires data from perianth, androecium, pod and seed, the affinity of 5. talpana, described from a single coUecrion bearing immature pods, cannot be justly evaluated at present. In gross aspect it suggests some form of distantly aUopatric S. guatemalensis, but differs in the long filiform style (±11, not 1-2 mm) which imphes a substantiaUy larger flower. Senna mul tifoliolata, a species of mountainous southern Mexico, has a simUar pod and seeds, but differs in the more numerous (7-14, not 4-5) pairs of leaflets. Senna koelziana, which occurs in simUar cool upland habitat not far distant from Talpa on Sa. del Halo in southeastern Jahsco, has a similarly elongate style but ovules very much more numerous (±64, not 16-20) which prognosricate a pod (unfor tunately not yet collected) ehher longer, plumper, or both. In the event that the pod of S. talpana breaks up, when fuUy ripe, into one-seeded segments, the
