116 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [VOL. 35 middle-Amazonian (Martius s.n. at M and Spruce 1110, 1558 in hb. Benth.) were referred by Bentham (1870, p. 104) to a mixed and imperfecriy realized Cassia hoffmannseggU, a name which, by lectotypificarion in this paper, has become a synonym of Senna latifolia. 9. Senna sandwithiana Irwin & Barneby, sp. nov., coroUae androecuque forma ut videtur S. bacillari proxime affinis, sed racemis simul e truncorum ramulorumque vetusriorum nodulis ac e foliorum maturorum axillis erumpentibus (nee corymboso-panicularis) diversa, fohis maximis nec non cauliflorescenria S. ruizianam (procul allopatricam) referens sed ab hac corolla majori leguminisque elongari recri seminibus 2 (nee 4)- seriaris remorior.—GUYANA, upper Mazaruni basin: n.-e. side of Mt.

Tillett ^5775.—paratypi fruct., K, NY. Trees 5-9 m with trunk up to 8 cm diam and terete, smooth, obscurely striate young branches, appearing glabrous up to the minutely pilosulous inflorescence but the branchlets, ventral face of If-stalk and margin of lfts often obscurely puberulous with fine incurved hairs up to 0.1-0.2 mm, the ample, thinly charta ceous reticulate lfts olivaceous subconcolorous, sublustrous above and duU beneath, the corymbose-paniculate inflorescences both cauliflorous from knobs on the trunk or old branches and axUlary to annotinous (older) lvs, but then much shorter than them. Stipules not seen, caducous from small pustuliform scars. Lvs (2-)2.5^ dm; petiole including longitudinally wrinkled pulvinus 2.5-7 cm, at middle 1.8-3.4 mm diam, the ventral sulcus shallow, defined by low thickened ridges; rachis 3.7-7.5 cm, almost always longer than petiole; gland 1 sessUe between proximal pair, plumply linguiform or ovoid-pyramidal obtuse, 1.5^ mm tall; pulvinules wrinkled 5.5-9 mm; distal pair of lfts very obliquely ovate- or obovate-elliptic, shortly acuminate, (12.5-)15-32 x (6-)7-16 cm, ±2-2.4 times as long as wide, at very base cuneately decurrent into the pulvinule but above this rounded to subcordate on proximal side, the forwardly incurved midrib with ±8-14 pairs of major camptodrome (and often some intercalary) secondary veins finely prominulous on ventral and sharply carinate on dorsal face, the fine tertiary and rericular venularion about equally prominulous on both faces, the ultimate defined areoles of the mesh
1982] CASSIINAE—SENNA 117 those of 4 median stamens 6-7 mm truncate, with divaricate beak ±0.6-0.8 mm, those of 3 abaxial ones 6-7.5 mm, contracted into a porrectly sigmoid beak 1.6-2 mm; ovary strigulose, the short style obhquely dUated into a cupshaped stigma 0.7-1.2 mm diam, the orifice 0.6-0.8 mm diam; ovules 186-208. Pod pendulous, short-stipitate, the stipe 5-6 mm, the body when fully formed (but unripe) straight subterete but obtusely 4-angulate 25-30 x ±0.8 cm, cuneate ly contracted at both ends, the firm brown valves rough and dull, evenulose, faintly constricted between the 2-seriate seeds; dehiscence and ripe seed un known.—Collections: 11.—Fig. 15. Rocky river-banks, sandstone cliffs, sometimes in Mora forest, 90-915 m, ap parently local, foothUls and middle slopes of Pakaraima Mts. about the sources ofthe Potaro, Mazaruni and Cuyuni rivers in Guyana and immediately adjoining Bolivar, Venezuela; and in n. Guyana also on the coastal plain, in unknown habitats along Waini and Barima rivers (Assakatta; Morawhanna), to be expected therefore in the Orinoco delta immediately n.-ward. Senna sandwithiana was first collected by the brothers Schomburgk in the region of Mt. Roraima in 1841. Their collection (Robert 881 = Richard 1523) was identified by Bentham (1971, p. 587) as related to Cassia bacillaris but left undescribed. The relationship in this direction is certainly a very close one, but the wholly or almost wholly cauliflorous inflorescences emergent from nodular swellings on the trunk and branches below the leafy canopy of the tree and their gently flexuous rather than abruptly zigzag prime axes seem significantly different. In general habit S. sandwithiana is comparable to the distantly allopatric S. ruiziana, but this has much smaller flowers and a short pod in which the seeds are doubled up into four rows. The fully ripe pod and seeds of S. sandwithiana may provide further differential characters. The epithet commemorates the eminent Kew botanist Noel Yuri Sandwith, who coUected the species in the Kaieteur gorge in November, 1937 (no. 1497, K, NY). 10. Senna oxyphylla (Kunth) Irwin & Barneby, comb. nov. Cassia oxyphylla Kunth, Mimoses pl. 39. 1822 & p. 129. 1823.—Typus infra sub var. oxyphylla indicatur. Shrubs and treelets 1-7.5 m, the slender subterete branchlets as often also the If-stalks, the dorsal face of lfts and the pod at least remotely and often densely resinous-punctate or -verruculose, the foliage and inflorescence varying from thinly strigulose with appressed hairs up to 0.2-0.4 mm to thinly or densely pUosulous with erect or loosely incurved hairs up to 0.3-0.65 mm, the lfts bicol ored, dull or sublustrous oUvaceous above, paler dull beneath, the inflorescence subcorymbose, paniculately corymbose or thyrsoid, either leafy at base, or leafy nearly throughout, or quite leafless, hence either exserted or not from foliage, its primary axis at maturity becoming abruptly flexuous. Stipules falcately oblanceolate-acuminate or linear, acute, 4.5-14 x 0.4-2 mm, when expanded arborescently venulose, usuaUy caducous long before the If, al ways deciduous before it. Lvs 7-I7(-19) cm; petiole including scarcely swollen pulvinus (0.7-) 1-5.5 cm, at middle 0.7-1.8(-2) mm diam, often a httle dilated upward, openly shallow- sulcate ventrally; rachis (6-)9-37(^0) mm, either a httie longer or shorter than petiole; gland between the proximal pair sessUe or shortiy stipitate, plumply ovate-lingutform obtuse or narrowly lanceiform acute 1.5-4 mm tall glabrous, a
