and is more tapered at the base ; but it is still doubtful if these dif- 

 ferences suffice to separate them. The leaves figured by Ettingshau- 

 sen in his ' Mora von Haring,' pi. 22, figs. 1-8, under the name of 

 Andromeda protogcea, belong, I think, to A. reticulata,

The seeds appear in great numbers in the upper three feet of the 

 " third division " of Forbes. These are probably the seeds which 

 he mentions as Carpolithes ovulum, var. 



They are brilliantly black, short oval, at both ends obtusely 

 rounded, 2|— 4 millims. long, and 2-3^ millims. broad, agreeing in 

 form and sculpture with those of Nymphoea, In many of the speci- 

 mens the fine stripes are to be seen with the aid of a lens, whilst in 

 others they are rubbed out ; they agree so well, however, in all other 

 points'^with the rest that they cannot be separated. 



It is undoubtedly the same species as that of Bovey ; it differs 

 from NymphcBa Charjoentieri (Heer, Flor. Tert. Helvet. pi. 155, 

 fig.20 6, c, c?) and JSf. Arethusoe, Br. {Carpolithes ovulum, Br.) by 

 the somewhat broader and shorter seeds. The NympJicea doliolum^j 

 Ludwig, is the iV. Charjpentieri, Heer.

Ehizomes and portions of leaves abundant, ; seven feet above the 

 *^ Black Band ; " one rhizome in the upper three feet of the *' third 

 division." 



Several large portions of leaves have been found, but no entire 

 leaves. They show us that the leaf was peltate, like that of Nelum- 

 hium. Fig. 19. Pl. XVIII. represents a portion of a young leaf where 

 the petiole was attached ; its venation is very indistinct ; one sees, 

 however, that one of the principal veins was stronger than the others, 

 which distinguishes Nelumhlum Buchii from other species. Other 

 portions belong to large, full-grown leaves, with well-preserved 

 veins, but do not show either the edge or the middle. The prin- 

 cipal veins are forked, the forks forming ' acute |[angles ; they are 

 forked again a little higher (Pl. XYIII. fig. 19 h, where a small por- 

 tion of a leaf is represented). Delicate veins unite the principal 

 ones ; and the areas they include are filled up with a fine reticula- 

 tion. 



There is no doubt that the rhizomes represented in Pl. XYIII. 

 figs. 19 c, d, e belong io' Nelumhium. r- The rhizomes of this genus 

 partly form knots, which are provided with a bunch of long fibres. 

 They show, therefore, quite another structure than the rhizomes of 

 Nymphma. These rhizomes - occur in the same bed with the leaves 

 of Nelumlliim Buchii, and therefore confirm the explanation given 



^ I received the seeds from M. Tasche of Salzhausen.
