I 2 and 13 belong to that species, and 14 and 15 to //. pauciflora. The 

 leaves sent with the latter point to the correctness of this identification.

When Bentham published Siphon in pauciflora, Spruce (Hook. Kew 

 Journ. Bot. vi. p. 370) he suggested that specimens in the Hookerian 

 herbarium from British Guiana, collected by Schomburgk, Parker, and 

 Hancock, might be the same species. Subsequently Mueller Arg., in the 

 place cited above, included Schomburgk's specimens under Hevea 

 panciflora without a doubt; and later (/7. Bras. xi. 2. p. 300) he 

 described Spruce's type (2691) of pauciflora under the name of 

 //. membra uacea ; under II. pauciflora he included Schomburgk's 

 Guiana specimens, and also gave Spruces locality of //. pauciflora, but 

 without a number. The types of all the species collected, and partly 

 described and named by Spruce, and published by Bentham, are in the 

 Kew Herbarium, and the only course is to retain the names for the 

 species to which they were originally applied. Parker and Hancock's 

 British Guiana specimens, mentioned by Bentham, are true H. pand- 

 flora, so far as can be determined from leaves alone. Further, Jenman 

 (726 and 24.10) and im Thurn (200) have both collected H. pauciflora 

 on the Mazaruni river, British Guiana. Of the distinct 1L gwhrnemi*, 

 Aubl., in which the anthers are 5 only and in one whorl (see pi. 2573, 

 tig. 9), we have only seen specimens from French Guiana. The details 

 of the flowers of //. confusa are given in plate 2574, figures 1-3 : 

 and the seed in plate 2575, figures 12 and 13.— W. Botting Hemsley.
