RECENTLY INTRODUCED TREES &c. PROM CENTRAL CHINA. 65 



The corolla is shaped like that of a Primrose, with a short tube and a 

 spreading limb composed of six to seven rotate segments and measuring 

 from 1^-1 J in. in diameter. 



It is figured in Hooker's "Icones Plantarum," tab. 2384, where Prof. 

 Oliver writes : " Excepting in the larger leaves, sometimes fairly if not 

 fully developed at the time of flowering, and much larger flowers, with 

 the limb of the corolla exceeding the tube, this plant might be regarded 

 as a glorified variety of Jasminum nudiflorum. It is evidently a very 

 free flowerer and in the very first rank of ornamental shrubs." 



Jasminum primulinum flowered at the Coombe Wood Nursery during 

 the past spring, both in pots in a cool house and on a north wall out of 

 doors, where it had stood for the past three winters. The latter situation 

 appears to suit the requirements of the plant best, much finer and more 

 numerous flowers being produced, and more foliage retained than when 

 grown in pots. A remarkable peculiarity is the way in which the flowers 

 become semi-double, and some, hose-in-hose, characters well depicted in 

 the Gardeners' Chronicle, March 28, 1903. 



Several forms of Buddleia variabilis are in gardens, but none so fine 

 as the variety Veitchiana which flowered and was exhibited in August 

 1902. It is a magnificent shrub. 



Buddleia albiflora is a new species first discovered by Dr. Henry, from 

 whose specimens it was named by Mr. Hemsley. The specific name is 

 unfortunate, as the flowers are not white but pale mauve with an orange 

 throat. It is quite hardy, very handsome, and flowered last year, proving 

 quite distinct from other species in cultivation. 



Buddleia asiatica is a small growing species with narrow lanceolate 

 leaves, 4 in. long by \ in. broad, dark green on the upper surface, white 

 beneath ; the inflorescence is both axillary and terminal, consisting of 

 racemes 4-6 in. long, of small white fragrant flowers. It has already 

 flowered in England as long ago as 1874, but so far as we know is not in 

 general cultivation. A figure is given in the "Botanical Magazine," tab. 

 ■6323, where Sir Joseph Hooker writes : "It is certainly remarkable that 

 so very common, elegant, and sweet-scented a plant as this, which flowers 

 for three months continuously in India, should not be in common cultiva- 

 tion." 



Pterocarya Paliurus takes its specific name from the resemblance its 

 fruit bears to that of Paliurus prcecox, a resemblance so close that when 

 the disc- shaped samara of the two are mixed it is a difficult matter to 

 separate them into their respective species. (Fig. 26.) 



Those Pterocaryas at present in cultivation are liable to injury by 

 frost, but from the vigorous condition of the seedlings and the cold 

 climate which this species endures in its native habitat it is reasonable 

 "to anticipate its hardiness in this country. It forms a tree 20-50 ft. in 

 height. 



Populus lasiocarpa is a handsome addition to our Poplars, discovered 

 by Dr. Henry in the province of Hupeh, where it is said to be common in 

 mountains from 4,000-6,000 ft. elevation. It forms a tree 20-40 ft. high 

 •and possesses the largest leaves of any in the genus : these are 10 in. 

 long by 7 in. broad, with a petiole 2-3 in. in length, broadly ovate-cordate 

 in outline with a finely serrated margin, dark green on the upper surface,
