ment in the distant views ; for the road lies very high for a conside- 

 rable portion of the way. The interest of West Lulworth lies entirely 

 in its singular broken shore, where we see the Purbeck limestone ris- 

 ing from under the chalk hills, with more or less of the strata of the 

 Wealden and of the green sand between them. In one or two places 

 the strata are absolutely reversed, and the green sand appears to rest 

 on a chalk very full of flints. The chalk strata are very much in- 

 clined, or quite vertical, as in the Isle of Purbeck, but the singularity 

 is, that there and here, these highly inclined strata are backed by ho- 

 rizontal strata of chalk. A little way west of West Lulworth is a 

 perforation in the limestone rock called Duddle Door, and near this 

 we find abundance of Statice spathulata. The leaf is rather broad, 

 with an uninterrupted margin continued behind the mucro. In 

 Sussex we have a variety with a broader leaf, but in which the mu- 

 cro is usually or always terminal. Crithmum maritimum is abun- 

 dant both on the chalk and the limestone, and on the chalk a form of 

 Arenaria marina, with a very stout, woody root, showing several con- 

 centric circles. Most botanists describe A. marina as an annual, I 

 doubt if correctly, and Babington inserts a p. ?. Erythraea latifolia, I 

 believe, occurs on the intermediate Wealden, but I am not very con- 

 fident in my power of determining this species. In the little, bay be- 

 tween Duddle Door and Lulworth I observed a good deal of a Bras- 

 sica which I had noticed in August, 1837, in this neighbourhood, 

 distinguished from B. oleracea by the turgid and seed-bearing beak. 

 My friends Mr. Borrer and the late Mr. Janson have assured me that 

 it retains this character in its progeny, and both agree that the plant 

 is distinguishable in all stages, though it would perhaps be difficult 

 to describe the difference so as to identify the plant independently of 

 the pod. I found this plant again the next day, on the little opening 

 to the shore which exists at East Lulworth, on the chalk cliffs. I 

 did not anywhere, observe it on the limestone, but Mr. Willcox in- 

 formed me that the quarry-men in Purbeck make use in the spring of 

 a cabbage they find on the cliffs. Query if this is the same, and also 

 if the plant of Dover cliffs have a seed in the beak. De Candolle has 

 a section of the genus Brassica distinguished by having a seed in the 

 beak, but these, with the exception of B. Richeri, belong to the genus 

 Erucastrum. The German and Italian Floras do not mention B. ole- 

 racea as a wild plant, and they have no species to which this can be 

 attributed ; for though two or three of them have constantly or occa- 

 sionally seeds in the beak, the descriptions are very different in other
