11. H. KAL.MI.SNUM Lam. Kalm's St. John's \Vort. 



Identification. Lam. Diet., 4. p. 148. ; Don's Mill., 1. p. 603. 

 Synonymes. H. Bartranuum Mill. ; Virginia St. John's Wort 



Spec. Char. $c. Branches tetragonal. Leaves linear-lanceolate. Flowers 3 to 

 ~-7, in a terminal corymb. Sepals lanceolate, bluntish. (Dim's Mill.,\. p. 603.) 

 A sub-evergreen undershrub ; a native of North America, in Pennsyl- 

 vania and Virginia; introduced into England in 1759, and producing its 

 yellow flowers in June and July. Height 3 ft. It was found by Mr. James 

 M'Nab in great abundance in the neighbourhood of the Falls" of Niagara, 

 in dry places ; and a variety of it (//. K. elongatum) was found in moist places 

 in New Jersey. This variety has flowers somewhat smaller than those of 

 the species, but they are equally rich in colour. (Ed. N. Phil. Journ., 

 vol. xix. p. 38.) This species is ornamental, forming a very neat compact 

 bush, and is in very general cultivation. American seeds ma}' be procured, 

 in London, at 6d. a packet, and plants at 9d. each ; at Bollwyller, 1 franc ; 

 and at New York, 25 cents. 



-* 12. H. URA^LUM Ham. The Urala St. John's Wort. 



Identification. D. Don Prod. Nep., p. 218. ; Don's Mill., 1. p. 607. 

 Derivation. From its name, Urala swa, in the Newar language. 

 Engravings. Bot. Mag., t. 2375. ; and our Jig. 107.| 

 Spec. Char., fyc. Branches compressed, 2-edged. Leaves elliptical, 



mucronulate, smooth, shining. Flowers terminal, somewhat corym- 



bose. Sepals oval, very blunt Petals orbicular. Styles shorter than 



the stamens. (Don's Mill., i. p. 603.) An undershrub, growing 2ft. 



high, introduced from Nepal, where it is found on the tops of 



mountains, in 1823 ; and producing its yellow flowers from July to 



September. In mild situations, and on a dry soil, it may safely be 



left through the winter without any protection ; but this should not 



be the case where the situation is cold, and the soil tenacious or 



humid.

Synonymes. J^ndrosae^mum constantinopolitanum fibre maximo Wheeler's Journey, 205. ; the large- 

 flowered St. John's Wort ; the large-flowering Tutsan ; the terrestrial Sun ; Aaron's Beard ; Mille 

 Pertuis a grandes Fleurs, Fr. ; grossblumiger Johannis Kraut, Ger. 



Derivations. This species was called /Jndrosje'mum by the old writers on botany, on account of the 

 tinge of red in different places on the stems, and the redness of the anthers, which were supposed 

 to give it the appearance of being spotted with blf>od. It was called Constantinopolitan from its 

 having been found near that city, in 1676, by Sir George Wheeler, Bart. The large size of its flowers 

 is remarkable, and has given rise to most of its other names. The name of the Terrestrial Sun is 

 very appropriate to the large golden flowers, with their long ray-like stamens, lying glittering on 

 their bed of dark green shining leaves, which spread over the surface of the ground. The number 

 and length of the stamens are, doubtless, also the origin of the name of Aaron's Beard.

Spec. Char. Stem tetragonal, dwarf. Leaves ovate, coriaceous, broad, full 

 of pellucid dots. Flowers large, terminal, solitary. Sepals large, obovate, 

 spreading ; capsule nodding. (Don's Mi/I., i. p. 603.) A beautiful little ever- 

 green, with shining dark green leaves, and bright golden flowers 2 in. or 3 in. 

 in diameter, and having innumerable reddish tremulous anthers. Height 

 from 1 ft. to 18 in. //. calycinum is a native of bushy places in the west 

 of Ireland and Scotland. It is extremely valuable for covering banks, rock- 

 work, or the surface of the ground in old shrubberies or picturesque woods, 

 especially for the latter purpose, as it thrives perfectly well under the drip 

 and shade of trees. The root creeps, and a small plant will soon extend 

 itself in every direction, especially if the soil be light, so as to cover a great 

 many square yards in a very short space of time. It is an excellent shelter 

 for game. Plants may be had, in the London nurseries, at Gd. each.
