280 THE FLOEIST AND POMOLOGIST. [December, 



in winter, leaving nothing visible but tlie cylindrical smootli reddisli-brown stems. 

 It is wortli cultivating in shallov/ ponds or streams, on account of its dissimilarity 

 to all other aquatics. 



The Water Dropwort, (Enanthe Jistidosa, is rather curious than beautiful. 

 It usually attains to the height of 2 ft. or 3 ft., the stems being quite hollow 

 or pipe-like, while the leaves vary from 4 in. to G in. in length, the radical ones 

 being twice pinnate, of a light-green colour, and bearing a marked resemblance 

 to those of the carrot ; hence its vulgar name of "Water OaiTot. The flowers, which 

 are collected into umbels, are of a pinkish-white, and produced about midsummer. 

 It is by no means showy, but being an umbelliferous plant, is worth culture for 

 the sake of variety. Let it be planted near the margin, as it is of small growth 

 when not in flower. 



The CE. pimpinelloides is another British species of smaller growth, but not 

 worth introducing into small collections. The (2J. carolincnsis (Tiedemannia tereti- 

 folia)^ with its singular filiform leaves, is not at present in cultivation. 



The Pohjgonxmi amphihium is a British perennial, not unfrequent in ponds and 

 ditches. Its prostrate stems emit at the nodes small roots like scarlet threads. 

 The leaves are alternate, 5 in. or Gin. long, by 1 to li- in. broad, lanceolate and 

 somewhat downy ; the flowers are borne in terminal, cylindrical spikes, and are 

 of a clear rosy-pink. The leaves lay flat on the surface, and the flowers stand 6 

 or 8 in. above the water. It is generally in full bloom in August, and is then 

 very showy. It should be planted near the margin. One form of the plant 

 grows and flowers readily in the ordinary soil of a garden, and this has a striking 

 resemblance, as far as the inflorescence is concerned, to P. Brunonis^ a plant sent 

 some years since by Captain (now General) Munro, from the northern parts of 

 India. — W. Buckley, Tooting.

({'''E have here a fine deciduous Oak, introduced from Asia Minor to the 

 Jardin du Museum, at Paris, some few years since, and of which an 

 account, accompanied by the annexed figure, has been published in the 

 Revue Ilorticole by M. Carriere. The plant appears to vary somewhat 

 from seed, the form here figured being taken as the type. It forms a vigorous 

 and handsome-looking tree, with spreading branches, having a brownish-gray 

 bark. The leaves are coriaceous, of a bright glossy green colour, elliptic-lanceo- 

 late, rounded and rather unequal at the base, margined with stiff spinescent 

 teeth. The male flowers, which open about April, grow in slender catkins, the 

 females, solitary or in pairs, appearing later in the summer, and as in some other 

 Oaks, taking a second year to arrive at maturity ; indeed in April, when the 

 males are in blossom, the young glans or acorns are already like small peas. The 

 cupules, which embrace about half of the acorn, are covered with numerous 

 fimbriate imbricated scales, the upper ones smaller and closer, and forming a 

 thick pad crowning the cupule. The acorns arc about \\ in. in length, and about
