MB. G. BENTHA.M ON TILIACE2E. 69 



subtus valde elevatis ; venulis transversis, conspicuis ; petiolo 1-lJ- 

 pollicari. Raccmi laxi, fructiferi, 2-3-poll. longi, subcompositi. Calvx 

 4-5-fidus, sepalis circa 2 lin. longis. Staminum nonnisi fragmenta 

 adsunt, hirta videntur ; antheris apiculatis. Capsula fere S. sinema- 

 riensis nisi stipite lineani longo fulta. 

 Hab. On the Casiquiare above the mouth of the Pacimone, and very 

 common in Cunucunuma, R. Spruce, n. 3197. 



18. S. pubescens, Benth. (Dasynema pubescens, Poepp. et Endl. Nov. 

 Gen. et Sp. iii. p. 74, t. 284.) 



Hab. In woods near Ega, on the Amazon, in North Brazil, Poeppig. 



I have not seen his specimens, but others from Cayenne, Martin, answer 

 perfectly to his figure and description, except that the pedicels are rather 

 shorter. 



19. S. cuneifolia, Mart. Herb. Fl. Bras. p. 94. 



Hab. In woods on the Amazon, in North Brazil, Martins. 



I have not seen authentic specimens of this species, but one of Blanchel's 

 from tropical Brazil, n. 2356, agrees with Martin's character. The flowers 

 and stamens are those of S. guianensis, of which it may prove to be a 

 variety. The leaves are larger, with petioles an inch long. 



20. S. microcarpa, Planch, in Herb. Hook. sp. n.? Glabra. Folia 

 obovato-oblonga, acuminata, 4-6-pollicaria, basi angustata; petiolo 

 1-3-lin. longo ; venis primariis subtus elevatis. Pedunculi breves, 

 pauciflori. Capsula sessilis, parva, setis rigidis echinata, fere S. 

 guianensis. 



Hab. Cayenne, Martin. 



21. S. guianensis, Benth. (Ablania guianensis, Aubl. PI. Gui. p. 585, 

 t. 234). Folia 3-4-poll. longa, petiolo 6-9-lin. longo. Antherac ex- 

 sertae, birtellae, filamento breviores, apicula quam anthera ipsa dimidio 

 fere breviore. 



Hab. Cayenne. I have a specimen derived from the Lambertian Herba- 

 rium, but without the collector's name. 



22. S. alnifolia, Mart. Herb. Fl. Bras. p. 94, n. 87. Folia 3-4 poll, 

 longa, obtusa v. brevissime acuminata, apicem versus subrepanda, 

 basi rotundata ; petiolo semipollicari. Racemi petiolo breviores. 



Hab. In woods near Rio Janeiro, Martius, Pohl, Mrs. Graham. 



23. S. riparia, Planch, in Herb. Hook. (Dasynema riparium, Gardn. 

 in Hook. Lond. Journ. Bot. ii. p. 324). Glabra. Folia ovali-elliptica 

 v. oblonga, acuminata, 3— 1-polliearia; petiolo 3-6-lineari. Racemi

 mouosperma, valvulis crassis, vix pollicaribus. Setae demissse, mol-
