166 4. CRUCIFER^. 



joint authority of himself and Mr. C. C. Babington, sup- 

 ported by Mr. Woods: "This interesting plant was detect- 

 ed on the sands near Pennard Castle, in the summer of 

 1838, by Mr. Woods. It was still plentiful when I visited 

 the spot in company with my friend, C. C. Babington, 

 Esq., in August last." But a manuscript note from C. C. 

 B., dated in 1843, assigns the locality of Pennard to S. 

 monensis ; and specimens sent to the Botanical Society of 

 London by Mr. Moggridge, from "Three Cliffs Bay, 

 Gower," are refemble to S. monensis. I presume, there- 

 fore, that Messrs. Woods, Babington and Flower at first 

 mistook S. monensis for this species, but that afterwards 

 Mr. C. C. Babington changed his opinion. Is this so .'' 



124. Raphanus Raphanistrum, Linn, f^ ^^- ^^^■/■^^/^ 



Area, general. 



South limit in Devon, Isle of Wight, Kent. '^ '- i^nM 



North limit in Shetland, Orkney, Hebrides. 



Estimate of provinces 18. Estimate of counties 80. 



Latitude 50 — 61. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 350 yards, in East Highlands. 



Range of mean annual temperature 51 — 43. 



Colonist. Agi-estal. A common and generally distri- 

 buted plant ; and yet apparently dependant on agriculture 

 for its permanence in this country, assuming the coi"n-field 

 weed to be specifically distinct from the plant of the coast. 

 On this account I class it among the colonists, rather than 

 among the certainly aboriginal natives.
