1680 The Trees of Great Britain and Ireland 



This tree occurs in northern China, at Jehol, and on the Po-hua mountain, west 

 of Peking ; and has also been found in the Moni Ula range, north of Ordos, in 

 Mongolia. It was introduced into cultivation by Dr. Bretschneider, 1 who sent seeds 

 from Peking to the Museum at Paris in 1880, and to the Arnold Arboretum in 1882. 

 The specimen in the Jardin des Plantes at Paris is about 20 ft. high. A small tree 

 at Kew flowered, when only 5 ft. high, at the end of July 1907. This species has 

 lately been introduced into the Coombe Wood Nursery by Mr. Purdom, who has been 

 collecting for Messrs. Veitch in northern China. (A. H.) 



TILIA PAUCICOSTATA 



Tilia paucicostata, Maximowicz, in Act. Hort. Petrop. xi. 82 (1890); Schneider, Laubholzkunde, 



ii. 371 (1909) ; V. Engler, Monog. Gatt. Tilia, 87 (1909). 

 Tilia Miqueliana, var. chinensis, Diels, in Engler, Bot. Jahrb. xxxvi., Beibl. No. 82, p. 75 (1905) 



(not Szyszylowicz). 



A small tree. Young branchlets glabrous, green. Leaves about 2\ in. long 

 and 2 in. wide, ovate, usually truncate and rarely cordate at the base, ending at the 

 apex in a long non-serrate acuminate cusp ; green and glabrous on both surfaces, 

 except for minute axil-tufts of pubescence beneath, which are, however, absent at the 

 base of the blade ; tertiary veins on the lower surface few, irregular, not parallel, but 

 anastomosing, more or less prominent ; margin with regular fine serrations ending 

 in long points ; petiole about an inch long, green, glabrous. 



Cymes erect, each with seven to fifteen flowers ; bracts glabrous, stalked ; 

 staminodes present ; style pilose at the base. Fruit globose, tomentose, faintly five- 

 ribbed. 



This species differs from T. cordata and its allies, in the prominent tertiary 

 venation and the green and not glaucous under surface of the leaf, which is usually 

 truncate at the base. It is a native of the provinces of Kansu, Shansi, and Szechwan, 

 in western China, where it was collected by Potanin, Giraldi, and Wilson. The 

 latter sent a living plant 2 in 1901 to Coombe Wood, which I consider to be probably 

 of this species. From it many grafts have been taken, and it now produces coppice 

 shoots with large leaves, which show at the base of the blade and on the adjoining 

 end of the petiole a trace of scattered stellate pubescence. This is probably a 

 juvenile character, disappearing on adult plants ; and a young tree at Kew, one of 

 the grafts, about 8 ft. high, bears leaves similar to those of the adult wild tree, though 

 slightly larger, and in these the stellate pubescence has almost disappeared.
