638 HYPERICUM 



the most disappointing in its flowers, which appear a few at a time from 

 July to September. It has a creeping root-stalk, and eventually forms a 

 large dense thicket ; it is thus easily increased by division. 



H. KALMIANUJVT; Linn&us. 



(Garden and Forest, 1890, fig. 24 ; Bot. Mag., t. 8491.) 



An evergreen bush, 2 to 3 ft. high, with angled branches. Leaves 

 glaucous green, I to 2 ins. long, \ to \ in. wide ; narrow-oblong or 

 oblanceolate, dotted with transparent glands. Flowers produced in small 

 cymes at the end of the branch and in the axils of the terminal leaves ; 

 f to I in. across, bright yellow ; sepals \ to \ in. long. Fruit ovate, five-celled. 



Native of Eastern N. America, where it is confined to the cliffs of rivers 

 and lakes from the Falls of Niagara northwards ; said now to have 

 become rather rare. It is named after Peter Kalm, the famous Swedish 

 naturalist and traveller who discovered it in 1750. Nine years later it 

 was introduced to England, but appears to have disappeared from cultivation 

 for a long period, the plants so-called being always H. prolificum. Mr 

 Dunbar, of the Parks Dept, Rochester, N.Y., has recently sent to Kew 

 seeds of the true plant. H. prolificum has narrower petals and not so 

 handsome a flower, also a three-celled fruit. (See densiflorum.} 



H. LOBOCARPUM, Gatlinger. 

 (Garden and Forest, 1897, fig. 57.) 



A free-growing shrub, 3 to 6 ft. high, with erect, angled branches. Leaves 

 narrowly oblong or oblanceolate, I to 2^- ins. long, scarcely stalked, margins 

 decurved. Flowers in dense cymes forming large leafy panicles ; yellow, about 

 \ in. across ; sepals about \ in. long, styles five ; fruit five-celled. Blossoms in 

 August and September. 



Native of the south-eastern United States in N. Carolina and Tennessee ; 

 introduced in 1898. It has very much the aspect of prolificum, but differs in 

 its five- celled fruit. (See densiflorum.} 



H. LYSIMACHIOIDES, Wallich. 



An evergreen or semi-evergreen shrub up to 4 ft. in height, but cut to the 

 ground at Kew in severe winters and not likely to grow so high ; branchlets 

 angled. Leaves ovate, pointed, f to i J ins. long, glaucous beneath. Flowers 

 in terminal cymes, each flower I to \\ ins. wide ; petals bright golden yellow ; 

 sepals \ in. long, linear-lanceolate ; stamens very numerous, in five bundles. 



Native of the west Himalaya ; introduced to France in 1894 by Mr 

 Maurice de Vilmorin, and to England ten years later. At Bitton, near Bristol, 

 it thrives admirably, forming a graceful bush 3 or 4 ft. high, and flowering- 

 abundantly. It is nearly allied to H. patulum, but differs in its narrow sepals 

 and smaller flowers. 



H. MOSERIANUM, Andre. 



(Garden, Dec. 17, 1898 coloured plate.) 



A hybrid between H. patulum and H. calycinum, raised in Mr Moser's 

 nursery at Versailles about 1887. It is a dwarf plant of tufted habit, sending 

 up arching, reddish shoots each year I to i J ft. long. Leaves intermediate 

 between those of the parents and up to 2 ins. long, ovate, rather glaucous 

 beneath. Flowers from one to five in a cluster at the end of the shoot, but not
