814 SHORT NOTES. 



Henry 0. Forbes. [Mr. Forbes' observations corroborate gene- 

 rally those of Senlior Mello and Mr. Spruce recorded in the * Journal 

 of the Linnean Society,' vol. x., p. 1 and tab. 1, and made in the 

 province of San Paulo, Brazil. — Ed. Journ. Bot.] 



A Correction.— In this Journal for 1874 (p. 369), I have put 

 on record a supposed variety of Zannichellia with spiral fruit, a 

 fragmentary specimen of which I found, without any indication of 

 locality, in the Kew Herbarium. Having lately passed through my 

 hands the Pvtamixjctons in the British Museum, I can refer this with 

 confidence to the N. American P. SpirUlus, Tuck.,'''' and take the fi! st 

 opportunity of rectifying my previous erroneous determination. 

 This remarkable species bears both submersed and emergent 

 spikes, which differ considerably ; the latter being on longish 

 peduncles and many-flowered, whilst the subaqueous ones are 

 almost sessile and reduced to a very few (1-4) flowers. Very 

 frequently the whole plant is submersed, and neither floating leaves 

 nor stalked spikes are then produced, the plant with its sessile 

 fruit and linear leaves closely resembling a ZanniclielUa. A very 

 similar specimen to the one I so misnamed ia hi Nuttall's her- 

 barium. He made it the type of a new genus, bearing the 

 (unpublished) name Cochlosperma from the shell-like fruit, and 

 described it as without calyx and corolla ! The specimen being 

 wholly in fruit must account for this, unless there should really be 

 any difference in this respect in the submersed flowers. — Henry 

 Trimen. 



Devon Plants. — A notice of my discovery of Scirj^iis parviilus 

 at Aveton Gifford, on the Avon, S. Devon, appeared in the ' Journal 

 of Botany' last year. On Sept. 1st of the present year I found it 

 at a second S. Devon station, growing in considerable quantity in 

 the mud and sand of some drains about the Pdver Teign, at Newton. 

 At both of its Devon stations it occurs some miles from the sea, 

 where the waters are tidal, but cannot be strongly saline. I could 

 not find any of the plants at Newton in either flower or fruit, 

 owing perhaps to the very wet season we have had. On Sept. Gth 

 last my brother found Vjupctnim niynim in plenty among Callima, 

 about half a mile to the north-east of the hill of Great Mistor, 

 Dartmoor. Some years ago a friend brought me a pi-,ce gathered 

 on the moor in the neighbourhood of South Brei^t, many miles to 

 the south-east of the Mistor station. Mr. Watson has recorded it 

 for S. Devon in * Topographical Botany,' so its occurrence at the 

 two places I have named makes no addition to the list of species of 

 the vice-county. — T. E. Archer Briggs. 



Euphorbia Paralias, L. — It is well known that the late 

 Dr. W. A. Broinfield sowed the seeds of Eiiphorhia Pdialias on 

 the sandy spits of St. Helen's and of Norton, both in the Isle of 

 Wight. On St. Helen's Spit I this year noted several plants in a 

 flourishing state ; I am not aware whether descendants exist from 

 the seed sowed at Norton. With the exception of a single plant
