other species known to me. Mr. Saunders's plant was sent 

 to Mm from the neighbourhood of Eio, by the late C. Bow- 

 man, Esq., and was grown in a cool stove in a mixture of 

 loam and peat : it is a slow grower, making a whorl of sixteen 

 to eighteen leaves annually. According to Miquel, this 

 species extends from the Amazons and Rio Negro to Eio de 

 Janeiro, and flowers in the month of December. 



Descr. Stem five to six feet high, stout, erect, glabrous, 

 covered with ashy-grey bark. Leaves crowded at the top of 

 the stem, very numerous, large and small irregularly mingled, 

 the former twelve to twenty inches long, the latter four to 

 eight ; all sessile, obovate-lanceolate, gradually tapering to a 

 very long base, acuminate, spinous-serrate, deep green 

 above, paler beneath, with very numerous horizontal reticu- 

 late veins. Racemes axillary, five to eight inches long, slender, 

 very many flowered ; pedicels slender, one-third to one-half 

 inch long, with a minute subulate bract in the middle. 

 Calyx-lobes small. Corolla one-fourth inch in diameter, 

 subglobose, bright orange-yellow ; lobes four, orbicular, not 

 spreading. Stamens four. Style short, stigma capitate. —
