 Brom., 130. — Leaves lorate, a foot and a half to two feet long, the 

 oblong dilated base four to five inches long, three inches broad, the 

 blade at the top of the base two inches broad, moderately firm in 

 texture, rounded with a cusp at the tip, armed with close ascending 

 horny prickles one inch and a half to two inches long. Peduncle 

 stout, one foot to one foot and a half long, with many red ascending 

 lanceolate bract-leaves three to four inches long. Flowers in a 

 dense oblong panicle six to twelve inches long, with numerous 

 ascending simply spicate distichous branches two to three inches 

 long, subtended by lanceolate entire branch-bracts, of which the 

 lowest are as long as the branches, the imbricated flow^ers each 

 furnished with a i^air of bracts, the outer one ovate-navicular, 

 miinitely cus^^idate, under half an inch long, the inner one smaller 

 and almost entirely adnate to the rachis. Calyx with ovary five- 

 eighths of an inch long ; sepals lanceolate, three-eighths of an inch 

 long, with a distinct cusp. Petals ligulate, yellow, little longer 

 than the sepals. Jamaica, Suartz. St. Lucia, Anderson! St. 

 Vincent, (iuilding ! Trinidad, Prestoe! Houston's Vera Cruz 

 plant, referred here by Schultes, is quite different, and will be 

 found under the section Hohenbergia. 



2. iE. MAETiNicENSis, Bdker, n. sp. — Leaves with a long entire 

 oblong base three to four inches broad, the closely minutely 

 serrated lamina not seen complete. Scape sheathed by xnany 

 large imbricated lanceolate bract-leaves. Flowers in a very dense.
