pectinatus growing in the same pond. Hence, as far as my 

 observations have gone, I am inclined to consider "scoparius" 

 " Vaillantii," and " pseudo-ma rinits" as mere states of P . flabell atus ; 

 I retain that name for the species because its author, Prof. 

 Babington, was the first to clearly separate it from the Linnean 

 aggregate, P. pectinatus. 



P. Jiabcllatus differs from P. pectinatus by its more robust and 

 less submerged growth, and by the more fan-like expansion of its 

 branchlets ; by its broad, flattened, 3-5 -veined lower leaves, and 

 above all, by its prominently keeled fruit. In P. pectinatus the 

 fruit has no central keel, and the lateral ridges are usually very 

 conspicuous. On transverse section the difference in the fruits of 

 the two species becomes very apparent, the dorsal margin of the 

 nutlet forming an elliptical arch in P. jiubellatus, while in P. 

 pectinatus it forms a rounded arch. 



P. jiubellatus inhabits both fresh and brackish water, and, 

 judging from its frequency in herbariums, is probably the commoner 

 form throughout Great Britain. 



My thanks are especially due to Prof. Babington for his careful 

 examination of the many specimens of this group which I have 

 submitted to him, and for allowing me to study the type-specimens 

 on which he founded this species. By this means I have been able 

 to identify the fruit of P. jiahellatus with that of P. scoparias. To 

 Messrs. Charles Bailey and Arthur Bennett my thanks are also due 

 for the loan of their valuable series of the plants of this group 

 collected in all parts of the world. 



By these aids, and by continued observations made year after 

 year in the field, and also by cultivation of various forms of the 

 pectinatus group, I have come to the conclusion that P. jhtbellatus 

 is a (jood species, bearing, perhaps, the same relation to P. pectinatus 

 as P. heterophyllus bears to P. Zizii or the latter to P. lucens.

On the death of this veteran botanist inJune, 1886, an inter- 

 esting biographical sketch appeared in the ■ 

 October of that year, which we then marke 

 P^ges, but which has hitherto been held over from want of space. 

 At the same time we had occasion to refer to the description of 

 Plants published by him in the * Edinburgh Philosophical Journal ' 

 for 1822 (pp. 319-333), which is prefaced by an account of his first 

 visit to North America. This narrative is not referred to in the 

 'Botanical Gazette;' and, as it presents many points of interest, 

 We reproduce it here. 



John Goldie was born near Maybole in Ayrshire, on March 

 21st, 1793, and was brought up a gardener. He married early, in 

 1815, and became connected with the Glasgow Botanic Garden, 



Douglas, he studied botany under
