elliptical, obtuse, naiTOwed into a sliort petiole, smootli and shining above, 

 the margins slightly recurved, the veins nuaierous, almost parallel, visible 

 especially on the under side, 1^ to 2^ in, long. Flowers small and singly 

 sessile along the simple or rarely branched rhachis of axillary shortly pedun- 

 culate spikes, scarcely above ^ in. long, and usually minutely pubescent. 

 Calyx about 1 line long, divided to about the middle. Corolla-tube very 

 sliortly exceeding the calyx, the lobes narrow, acute, nearly as long as the 

 tube. Anthers almost acute. Ovary pubescent. Fruit larger than in 

 A.bHxifoUa,i\\^ articles usuallv solitary, vai-ying from globular to ovoid. —

6. A. thyrsiflora, BenlL A glabrous slirub. Leaves usually iu 

 ^'hoiis of 3, obovate or oblong, rery obtuse, narrowed into a petiole of 2 or 3 

 lines, tlie margins slightly recurved, smooth and shining above, the veins 

 parallel hut very obscure and not so numerous as in A. spicata. Flowers 3 

 to 7 together in little heads or clusters, pedicellate or nearly sessile along the 

 Aachis of small axillary thyrsoid or spike-like panicles, the upper ones some- 

 times singly sessile, all rather smaller than in J^obtusifoUa. Calyx-segments 

 narrow and acute. Corolla-tube slender, 2 or 3 times as long as the calyx 

 the lobes ovate, much shorter than the tube. Ovary glabrous. Articles ot
