334 EAST ANGLIAN BOTANY. [November, 



this valley of the Yare and Waveuey, the results of which are 

 now to be communicated to our readers. 



On the 15th our walk was along the right bank of the Yare 

 as aforesaid. All the rivers here are navigable, and are all en- 

 closed by a high liank to prevent the tidal waters and land-floods 

 from overflowing the adjoining marshes ; these are mostly mea- 

 dow or pasture, but there are here and there some cultivated 

 fields. 



The broad on the Yare, named Braden, was almost full of 

 Zostera marina* not yet in flower nor fruit. Pucus vesiculosus 

 and a few other marine plants were attached to the stone-lined 

 water wall ; also here and there grew Artemisia maritima and 

 Apium graveolens, both on the earthen mound and at its base ; 

 Hordeum maritimum was about equally common; Glaux inari- 

 tima and Lepidium ruderale were seen everywhere, the latter on 

 the top or sides of the bulwark, the other on the moist ditch- 

 sides below. 



Note. Our conviction about the reported growth of Lepidium 

 latifolium and Frankenia Icevis in this neighbourhood, i. e. near 

 Yarmouth, is that these two plants are equally uncommon or 

 scarce everywhere on the eastern coast ; and furthermore, that 

 Glaux maritima and LepAdium rudtrale, through some oversight 

 of the reporter, were elevated into the place of the very much 

 rarer plants reported. We do not insinuate that the Frankenia 

 and the rare Lepidium are not there because we did not see 

 them ; only an error is suspected when two plants are omitted 

 usually incorporated in such lists, and which are moreover so 

 abundant that they could not have been unobserved. 



In the ditches we saw plenty of Potaniogeto7i pectinatus, P. 

 gramineus, and other still undetermined species; also Juncus 

 coenosus, J. obtusiflorus , J. acutiflorus, and probably J. maritimus. ' 

 Scirpus maritimus was seen everywhere, and Alt/uea officinalis 

 was far from scarce, but at this period, 15th July, not yet in 

 flow-er. Rumex maritimus or R. palustris, possibly both, were,, 



* We did not know when we saw thousands of acres (square miles ?j covered ' 

 with the long, narrow, Qoatuig leaves of this plant, that it was destined to be a sue-''" 

 cessor to the far-famed Sea-Island Cotton of the Southern States of America. We-ri 

 do not know what amount of fibre it yields, nor are there as yet any reliable ac- ;. 

 counts pubhshed about the fineness and tenacity of its tissues, but plenty of the 

 plant is attainable, and at no great cost.
