36606. PLEIOGYNIUM SOLANDRI. From J. F. Bailey, Brisbane, 
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 
backgrounds 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 
determine 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 attaining 
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.
