36606. PLEIOGYNIUM SOLANDRI. From J. F. Bailey, Bris- 

 bane, Queensland, Australia. A moderate-sized tree, 40 to 60 feet 

 high with a trunk 2 to 3 feet in diameter. Timber when first cut 

 is soft, but afterwards becomes hard and tough. Possibly of use as 

 a stock for the less hardy mango, cashew, or Spondias. 



26614. POPULUS BEROLINENSIS. Poplar, var. Rossica. 

 From F. N. Meyer, Liesnoi, Russia. A very hardy variety of the 

 ordinary Berlin poplar, widely planted in and around Petrograd as a 

 shade tree; mostly closely pruned there, but of open habit of growth 

 under ordinary conditions. 



22447. POPULUS BREVIFOLIA. Chinese poplar. From 

 F. N. Meyer, Taijatsoa, China. An extremely slender but very 

 graceful tree, suitable for grouping in parks and for forming back- 

 grounds for other tall deciduous trees. The buds and young leaves 

 exhale a pleasant balsamic odor. Partial to moist, sandy soils, suc- 

 ceeding especially well along watercourses. 



22363. POPULUS SIMONII. Poplar. From F. N. Meyer, 

 Shiling, Chihli, China. Forma, fastigiata. One of the balsam poplars, 

 the odor of which is particularly noticeable when the young leaves 

 are developing. This form looks somewhat like the Lombardy poplar, 

 but makes a more pleasing impression. Thrives in sandy soil. 

 Hardy at Arnold Arboretum, near Boston, Mass. 



34779. POPULUS SIMONII. Chinese poplar. From Angers, 

 France, through Charles Detriche. Coming from south China, where 

 the climate is warm and moist, this species may prove tender north 

 of Georgia; although being deciduous, it deserves a wide trial to deter- 

 mine its range. It may prove to be adapted to cultivation south of 

 the range of poplars in Florida. 



26812. POPULUS SINENSIS. Poplar. From F. N. Meyer, 

 Orianda, Crimea, Russia. Stately white-trunked tree, often attain- 

 ing a height of 80 feet or more, with a remarkable pyramidal habit. 

 Old trees branch out and lose their pyramidal shape. Of value in 

 the Western States for windbreaks and as an ornamental park tree. 



22861. POPULUS SUAVEOLENS. White-barked poplar. 

 From F.N. Meyer, Wutaishan, Shansi, China. Grows at high altitudes 

 and is valuable for sand binding. Frequently planted along ravines 

 to prevent erosion and damage to lands below. Suggested for similar 

 use and avenue planting in this country. The young bark of the . 

 tree is green.
