BRITISH BOTANY. 



R. Raphanistrum, Lin. Wild Radish. — e.b.856. l.b.s. 124. 



A. 18. C. 80. Lat. 50-61°. Alt. 0-350 yds. Tern. 51-43°. This 

 plant has been seen in one of our midland counties at an elevation 

 of 300 yards. 



Root tapering, vertical, slender. Stem erect, branching, 1-2 

 feet high, rigidly hairy. Leaves lyrate, rough, with a large 

 toothed terminal lobe. Flowers large, yellow or white with 

 bluish-violet veins. Pod linear-oblong, moniliform (necklace- 

 like), when ripe separated by transverse partitions forming one- 

 seeded cells, abruptly contracted into a long subulate beak. 



Fields. Annual ; May- August. — A very variable plant. 



R. maritimus, Sm. Sea Radish, — e.b. 1643. l.b.s. 124 6. 

 A. 7. C. 10. Lat. 50-56°. Alt: 0. Tern. 52-48°. 



Root large and succulent. Stem 3—4 feet high, rough chiefly 

 at the base. Root and lower stem-leaves more serrated than in 

 R. Raphanistrum ; upper simple and serrated. Flowers yellow, 

 and less veiny than in the above species. Pods more strongly 

 and broadly furrowed, not rough. 



Smith in Eng. Flora, vol. iii. p. 227. 



R. Landra, Moretti. — The upper leaves of what we suppose 

 may be this species are coarsely serrated, with very unequal 

 sharp teeth. The flowers are much smaller than in the pre- 

 ceding species (forms ?) . The style is three times as long as in 

 R. sativa, becoming a long tapering beak, usually longer than 

 the pod, which consists of 3-4 joints. — Is this plant, which grows 

 about Wandsworth and Battersea, a variety of 7?. maritimus ? 



Neslia paniculata, Desv., has been collected during the last 

 four years in the Adcinity of Chelsea and Battersea, and espe- 

 cially near the Steamboat-pier, Wandsworth, 



It may be readily distinguished from the genera and species 

 in this section by its rounded, bony, wrinkled pouches, which are 

 in lax panicled clusters. The stem is quite erect, usually simple, 

 rough and hairy. Leaves oblong-linear or lanceolate-clasping, 

 toothed, more or less rough. 



Annual; June- August. 



The following plants were also abundant in the Wandsworth 

 locality : — 



. Biplotaxis erucoides, DC. — Flowers large, white veined with 

 violet. Root-leaves lyrate; stem-leaves pinnatifid, with short 

 blunt lobes.
