 Description. — Stem woody, rough. Branches covered with dense, green- 

 ish tomentum, which withers and remains long attached. Leaves scat- 

 tered, light green, stalked, spreading, lanceolate, strongly veined, waved 

 or crisped, covered with harsh jjubescence on both sides, the middle rib 

 and veins projecting much on the under-side, the former above also. 

 Petiole erect, grooved above, pubescent, purple before fading, about a 

 sixth of the length of the leaf. Stipules geminate, varying in size, the 

 largest upwards, broadly falcate or kidney-shaped, horizontal and bend- 

 ing round the branch, more glabrous than the leaves. Peduiwles (about 

 an inch long) axillary and terminal, generally about twice as long as the 

 petioles, slightly flattened and dilated towards the flowers. Pedicels 

 very short, stout, straight, slightly pubescent. Flowers fascicled, nod- 

 ding, of a uniform pale yellow. Bractece single at the base of each flower, 

 with the exception of the central one, spathe-like, appressed, acuminate, 

 and coloured like the flower, pubescent. Calya: about as long as the pe- 

 dicel, pubescent within and without, nearly cylindrical, with five strongly 

 projecting ribs on the outside, leading to five slightly connivent acute 

 teeth. Corolla inferior, hypocrateriform, pubescent without, smooth with- 

 in ; tube nearly an inch "long, dilated a little upwards, and contracted at 

 the throat : limb 5-cleft, segments ovate, acute, spreading at right angles 

 to the tube, each with two strong ribs projecting behind. Stamens five ; 

 filaments inserted immediately above the middle of the tube, each having 

 a tuft of matted hairs piojecting from the inside at their base, above this 

 straight and smooth, nearly' reaching to the faux. Anthers bilobular, 

 short, connivent, bursting laterally : pollen yellowish-white. Stigma sap- 

 green, nearly round, but flattened a little at the top, raised above the 

 anthers, and projected into the faux. Style (three quarters of an inch 

 long) nearly colourless, filiform. Germen roundish or obovate, smooth, 

 yellowish-green, obscurely furrowed, seated on a small yellow disk. 

 Ovules numerous, ol)ovate. 

 We received this jjlant from the Botanic Garden of Berlin, in June 1828. 

 It is a native of Brazil, and blossomed in the stove of the Edinburgh 

 Botanic Garden in December 1829, producing, during a considerable 

 time, a succession of rather ornamental flowers.
