 broad : petiole 1"' long ; corolla-tube 3'" long ; capsule 2'" diam. — Hab. Montserrat (Sw.), 

 Grenada !, Oerst. ; [Portorico !, S. Thomas !, S. Croix, Martinique]. 



59. R. buxifolia, V. Leaves spathulate, bluntish, glabrescent, hairy on the midrib 

 and margin ■. stipules deltoid and terminated with a long mucro, strigose ; peduncles in the 

 uppermost axils, nearly as long as the leaves, & -flowered, pubescent : pedicles of equal

R. laevigata, DC. (Sieb. Tr. 374), is unknown to me : from its diagnosis it approaches 

 R. arborescens, but its leaves are said to be oblong or elliptical, acuminate at both ends. — 

 R. odorata, Jacq. (Amer. Pict. t. 61), is a peculiar species, occurring in our Cuba collections, 

 distinguished from the other Eurondeletiee by having terminal corymbiform cymes. 



Sect. 3. Stevensia, Poit. — Segments of the calyx-limb ovate or lanceolate, as long as or 

 longer than the tube. — Peduncles axillary, terminated by a cluster of sessile flowers, 

 which is supported by an involucel, rarely 1-flowered. 



R. Poitaei, Gr. (Stevensia buxifolia, Poit. !) of Haiti ! and Cuba ! (Wr. Cub. 1266), is a 

 true congener, having a loculicide capsule, distinguished from the following species (of which 

 the fruit however is still unknown) by shorter 1 (-3) -flowered peduncles. The increased 

 number of flower-parts described by Poiteau is a monstrosity : the regular number is 4 or 5.. 



60. R. hirta, Sw. Shaggy -pilose above ; leaves chartaceous, ovate or elliptical, shortly 

 acuminate, rounded or bluntish at the base, pilose above with long, scattered hairs, or at 

 length glabrate, shaggy-pilose, chiefly on the nerves beneath : stipules deltoid-subulate, 

 woolly ; flowers clustered : peduncles 3-fid or simple, as long as or exceeded by the leaves •. 

 involucral leaves lanceolate, distinct, resembling the calyx-lobes, which are lanceolate, acu- 

 minate, much longer than the tube ; corolla-tube filiform, clavate above, externally shaggy- 

 pilose, glabrous within, twice as long as the calyx-lobes ; anthers 5, oblong-linear, included, 

 inserted below the corolla-throat, 6 times exceeded by it in length. — R. umbellulata, Macf. ! 

 (non Sw.). Confounded by DC. with R. hirsuta, Sw., which has pedicellate flowers, and 

 twice shorter, somewhat stiffer hairs on the leaves, the ambiguous term " hirtiis " having 

 been employed by Swartz in the sense of " hairy with long weak hairs," while the usual 

 meaning of " hirsuta " gives no idea of his R. hirsuta. Leaves 5"-3" long, 3"-l$" broad : 

 petiole 6"'-4'" long ; peduncles shaggy, stiff or lax, 4"-14", divisions 6'" long ; corolla- 

 tube 4'" long. — Hab. Jamaica !, Macf., Wils., among mountain-shrubs. 



61. R. ipcana, Sw. Shaggy- woolly above; leaves rigid-leathery, oval-oblong, blunt, 

 hairy on the upper side with long, decumbent, weak down, at length shining -glabrate, with 

 the veins and midrib deeply impressed, on the under side hoary with branched wool -hairs : 

 atipules oblong, pointed, deciduous ; clusters 3-flowered : peduncle simple, twice as long at 

 the petiole -. involucral leaves distinct, ovate, pointed ; calyx-lobes ovate-lanceolate, shaggy-
