A SUPPLEMENT TO THE 'FLORA VECTENSIS.' 137
Obs. D. deJioides, L. Was observed by the Rev. E. Venables in the grounds of " The Hennitag-e," growing on land previously cidtivated. Miss E. Twining included D. ddtoides in a list of Isle of Wight plants which she sent to Mr. Watson, but I fear that the plant has x^.^ claim to be considered native, or even permanently estal)lished.
- Saponaria oJficlnaUs, L. Clifi" below the Fort at Freshwater Gate,
but not native (H. C. Watson) ; hedge close to Brightstone, an escape from or adjoining to a garden (R. Tucker).
Obs. S'dene iioctiflora, L. Must be erased from the Isle of Wight list, as Mr. Harabrough told me that he felt uncertain about the single specimen which he once picked when out shooting.
Sagina ciUata, Fries. In a furze brake at Steephill (A. J. Hambrough) ; on a bank near Sandown ; in the Warren at Alum Bay ; at Liccombe ; gravel pit at the junction .of the roads to Fishbourne and Ryde (Uev. A. M. Norman), etc., but far less common than *S'. apetnla.
S. amhifjua, Lloyd. On sandy banks near the Fort in Sandiwn Bay, 1856. This is, I believe, a seaside form of S. cillata, with fleshy leaves and stouter habit.
S. snbulata, Sw. On Freshwater Down, near the site of the former lighthouse (A. J. Hambrough).
XSperrpila arvemls, L. In the Isle of Wight I have found only the variety^, vulgaris (Bonng.). This agrees with the experien 'C of Le Jobs and Mabille on the opposite coast of France.
Stellaria neglecta, Weihe. In damp shady places, rather scarce. North side of Centurion's Copse, 1860; roadside near Apse Heath and near Shanklin ; in Cowpit Clift' Wood, with pedicels quite glabrous an I smaller petals ; near Landguard Farm and near Great Combley Farm. Well marked in the most typical form by the ten stamens, the long-reflected pedicels, and the large petals, which catch the eye even when the flower is closed ; but it must be confessed that plants often occur which it is difficult to refer to S. neglecta or *S'. media.
S. Boroeana. iovA.^Alsine pallida, Dum. Sandhills at St. Helens and above Sandown Bay. Still less distinct from S. media than the former. Ryde and Niton (Bromf.), sub var. y.
Cerastium triviale, /8. holosteoides, Fries. On the top of Shanklin Down, sparingly ; on Bembridge Down, near the Fort, with C. pianiluni, 1858.
C. pnmilum, Curt. Abundant on Bembridge Down, especially near the edge of the cliff, 1858; on Brading Down; Afton Down, Frediwater. This plant is very different from both 6'. semidecnndrnm and C. triviale, but is very closely allied to C. tetrandrum, to which it is indeed joined as a variety by Cosson and Germain. Besides that the edge of the bract is membranous, the stems of C piiniilum branch in a more regular manner from about the middle, while in C. tetrandrum the stems branch from quite low down, and tlie dichotomy is developed on one side only. In the stiape and veining of the petals, C. piimilum agrees closely with C. tetrandrum, while both differ from C semidecandrum. The plant iflen- tioned by Dr. Bromfield as growing near the Ferry House at St. Helen's is Q. tetrandrum.
C. tetrandrum, Curt. Occurs in a few places at some distance from the sea, as on Ninham Heath and Pan Common. I once found on Pan Common a few plants with the foliage and stems quite glabrous, calvx
