POLYGON A CEJE. TRAGOPY RUM. 



J 293 



Spec. Char,, $c. Stem spreading widely. 

 Leaves lanceolate, tapered to both ends, 

 flat. Ochrea lanceolate, shorter than the 

 internode. The 2 exterior sepals reflexed, 

 the 3 interior ones obcordate. Flowers 

 octandrous, trigynous. A native of Sibe- 

 ria and Dahuria. (Willd.) A shrub, a 

 native of Siberia, growing from 1 ft. to 

 more than 2 ft. high, branchy, even to the 

 base. Introduced in 1770, but rare in 



collections. Branches twh 



Leaf with 



a frosty hue, spathulate-lanceolate, nearly 

 1 in. long, several times longer than broad ; 

 its edge obscurely indented. The petiole 

 short. The ochrea ends in 2 acuminate 

 points. The flowers are borne on terminal 

 twigs, are pediceled, erect, axillary, 1 — 3 

 in an axil, often 3, and arc so disposed as 



to constitute leafy racemes. The calyxes are whitish, variegated with 

 rose colour, and persistent ; and of the 5 sepals to each flower, the 3 that 

 invest the ovary after the flowering become more entirely rosy. The pedicels, 

 erect while bearing the flower, after the flowering become deflexed,and render 

 the fruit pendulous. {Bot. Reg.) There is a plant in the Horticultural 

 Society's Garden, in an unfavourable situation, being much shaded by 

 trees, which is upward of 1 ft. in height ; and there is one in the arboretum 

 of Messrs. Loddiges, which forms a hemispherical bush 2^ ft. high; which, 

 during great part of July and August, 1836, was covered with its beautiful 

 white flowers, tinged with pink ; and formed a truly admirable object. It 

 thrives best in peat soil, and is worthy of a prominent place in the most 

 select collections.

Spec. Char., cfc. Leaf obovate, obtuse, tipped with a short 

 mucro ; the lateral margins undulated and reflexed, 

 glabrous. Ochreas with 2 awns. (Shns in Bot. Mag, t. 

 1065.) A shrub, a native of Siberia. Introduced in 

 1800, and flowering in July. Its decumbent branches 

 will extend 2 ft. and upwards on every side of the root ; 

 their bark is ash-coloured. The leaves are of a light 

 green colour, rather rounded in outline, about 1 in. in 

 diameter, and deciduous. The flowers are produced in 

 long racemes, are nodding, and white. The fruit is 

 enclosed by the 3 inner sepals, which become, as the 

 fruit ripens, of a rosy colour. This, and the preceding 

 species, are extremely interesting and beautiful little shrubs, and it is much 

 to be regretted that they are so very seldom seen in collections. Though 

 they require heath soil, and some little time to be firmly established, yet 

 when once they are so, from their compact neat habit of growth, very little 

 care will be necessary afterwards. They never can require much pruning, 

 are quite hardy ; and, provided the soil be not allowed to get too dry in the 

 heat of summer, they are always certain of flowering freely. We hope in 

 due time to see our provincial horticultural societies encouraging the growth 

 of plants of this kind, by offering premiums for well grown specimens ; and 

 for those who collect the greatest number of sorts.
