132 TWO OLD AMERICAN TYPES. 



nerves sometimes hairy. Tiie inflorescence is copiously branched, 

 the sepals exappendiculate, and the stipes longer than in the next 

 species. 



H. PoPAYANENsis H. B. K. Nov. Gcn. v. 341 (1821). H. ameri- 

 canus L. var. f3 Popaijanensis K. Schum. /. c. 



Hab. New Granada : Prov. Popayan, Triana ! Prov. Bogota, 

 Trianal St. Martha, Fcf?i 7io//r ! Peru, Tarapoto, Spruce, ^oA^6^, 

 has been referred here by Dr. Schumann. Bolivia, Mapiri, Bang, 

 1491, referred here by Mr. Rose. 



This plant differs from H. americana L. var. Schumcmni by the 

 leaves, which are glabrous on neither surface ; below they are 

 fuscous subtomentose, with the nerves and veins hirsute ; above in 

 the original description they are said to be "adpresso pilosiusculis." 

 They are subrotund and often trilobed. 



There is in the National Herbarium a type of Triwnfetta hirta 

 Vahl, Symb. iii. 63, from St. Martha, collected by J. van Rohr. 

 M. Triana has referred this to Heliocarpus Fopayanensis H.B.K., 

 and I agree in the identification. 



Var. PuRDiEi. Foliis ovatis lobatis praecipue subtus molliter 

 tomentosis basi cordatis, inflorescentia paniculata ramosa. 



Hab. New Granada, near Velez, Purdie, Herb. Kew. 



The leaves of the above variety are much more densely tomentose 

 than in the type. 



Var. TRicHOPODA. H . tricJiopodus Turcz. /.. c. 226. 



Hab. Venezuela, near Galipan, Funck d Schliw, 150 ! (type). 

 Columbia, Moritz, 210! Panama, Cuming, 1131! Sutton. Hages, 

 437 ! Venezuela, Fendler, 1277 ! 



Triana (Prod. Nov. Granat. 221) unites this with H. Popaya- 

 nensu H. B. K. I think, however, it may take varietal rank. The 

 differences being that in tricliopoda tlie stipe is longer, and the 

 nerves of the leaves on the under side are not so hirsute. 



H. ARBOREscENs Seem. Bot. Herald, 86 (1852-57). 



Hab. Panama, Seemami ! 



This is reduced by Dr. Schumann to R. americana, but is con- 

 sidered, correctly I think, by Mr. Rose as a distinct species. It 

 more resembles the true H. americana than any other species, 

 but the leaves have a long acuminate point, and the sepals are 

 appendaged. 



H. APPENDicuLATA Turcz. /. c. 226. 



Hab. Mexico, Linden, 1605 ! Guatemala, Capt. Donnell Smith, 

 No. 1723 ! Costa Rica, Talemania, Tonduz. 



This seems a good species — the leaves are discolorous, being 

 reddish white below. The type is in very young fruit, and has a 

 very short stipe ; tliis, however, doubtless lengthens, and I have 

 compared the Guatemalan specimen, and have no reason to doubt 

 its being correctly named, although it is in a late-fruiting stage. 



The remainder of Mr. Rose's species do not suggest matter for 

 comment.
