lalcd to IJ. foliarea. Altliough coiimioii in the eastoni 
counlios of Kiiglaiul, it is p()ssil)lo that this tr(‘(3 camiol l)o 
seen in the United States outside of tlie Arl)oretuin, 
Ulmus noLLAisnicA, This f^eneral name Inis been giv('n 
to a raee of natural hybrids between U. foUared and U. 
(/lafmi, among wliieh are some of the lnindsom(!sl and 
most valuable of the European Elms. To the best known 
in this country of these hybrids the name IJlniKs JiolUui- 
(fira vegela has been given. This tree was raised in a 
nursery at Huntingdon about the middle of the eighUa'iith 
century and is usually called the Huntingdon Elm. This 
tre(3 often grows one hundred feet high with a massive; 
trunk and spnviding and ascemding branches which make 
a vase-shaped IhnkI which readily distinguishes this tree 
from oth(*r Elms. It can be seen to good advantage in 
('ambridgeshire, England, especially in Cambridge, where 
theie is a noble avemue of I lie Huntingdon Elm. A tree 
of this hybrid which grew in the grounds of Magdalen 
College at Oxfoi'd was believed to be the lai’gest tree in 
(Ireat Hritain. In April, 1911, this tree was blown down 
and was found to be one hundred and forty-two feet high 
w ith a trunk twenty-seven feet in circumfei’ence at live 
feet above the ground. In this country this hybrid Elm 
grows more rapidly than other Elm-trees, and as it pro¬ 
duces suckers it can he easily multiplied. It is not com¬ 
mon here, however, although in the neighborhood of bos¬ 
ton specimens not more than sixty years old have already 
grown to a large siz(‘. The var. belgira of this hybrid is 
tin; Elm w Inch has been most often planted as a stiiad and 
roadside trei; in Helgium and Holland. It is a lall tree 
with a straight, rough-barked trunk, a broad head of 
rather er(‘ct branches, and dark green leaves slightly 
roughened above and covered below^ with soft (low n. As 
this tree grow s in Holland it is one of the handsonu'st and 
most d(‘sirahle trea's for shading city sti’i'cts. This Elm 
ajipears to he little known in the United Slat(‘s; it is 
grow ing w (‘ll in tin' Arhondum, but it has not Ix'cn Ium'c 
long enough y(‘t to show if it w ill be of [leinianent valm* 
in New England. Tin; co-salled Dutch Elm, VInuis ninjor 
of many English dendrologists and a common tr('e in 
English parks, is probably another hybrid of tin; same 
parentag(‘ {IJ. hoUandira var. major). This is a vmy 
large tree with a short trunk covered with lough bark, 
w ide-spi‘eading branches furnished w ith corky w ings, 
and dark gf’c'cn h'aves lustrous and nearly smooth on tin* 
upper surface and slightly downy below^ As this tree; 
|)roduces many suckers it can be ('asily multiplied. 
Ui-Mijs LAKMS. This is a common Elm in norlh(*rn 
Hiissia and in so,m(‘ parts of Scandanavia, and occurs oc¬ 
casionally in l)(‘nmark and the Balkan countri(‘S. It h;is 
h(‘(‘n glowing in the Arlioretum since 1888, and is now 
lifty-five feet tall w ith a short trunk, a liroad pyramidal 
head and dark gioen foliage. Botanically this Elm is 
closely related to the American White Elm {Ulmus umcr- 
irana) but differs from it in the thicker coat of dow n on 
the lower surface of the leaves and in its lai'ger and 
sharper-pointed buds. The leaves of this tree unfold 
her(‘ earlier than those of any other Elm. It is |)robably 
extremely rare in the United States, but American tree* 
lovers can w isely learn more about it. 
The Arboretum Collection now^ contains sixty-two dif¬ 
ferent Elms and includes all the know n speoies w ith the 
exception of the four Himalayan Elms and the Mexican 
Elm which are not in cultivation and two specie's from 
tin; soutlu'rn United States which an; not hardy h('re. 
With few ('xc(‘j)tions the important and inten'sting var¬ 
ieties and hybrids an* rejuesente'd in the colh'ction. Many 
of tin; jilants are' still loo small to {iroduce' fruit or to 
show the habit of mature trees, but as a whole' the' col- 
h'clion oilers a good opportunity for the study of the 
h'aves and hranchh'ts of Elm- tre(;s. 
A coon Bhododenduon. To a Bhododendron which is 
grow ing in Mi', llunnew eirs gareh'n at Welh'sh'y I In* 
name; of (llennyi has been given. This name; is prohahly 
not corre'ct, at least it is not found in the' catalogues of 
garde'll Bhododendrons. There was on(*(', howe've'r, in 
England a Mr. (Ih'imy w ho raised hyhriel Bhodode'iidrons, 
for on llu' 5th of Ee'bruary, 1858, at a me'i'ling of the' 
Moyal Horticultural Society in London, “Mr. (le'orge; 
(ih'imy ('xhihile'd a Bhododendron said to have' b(;e'n 
raised hy himself from se'cd. It did not ajijiear dillerent 
from a varie'ly raised some years since by Mr. Wale're;r, 
of Knafihill, and called in the gardens /». pulr/unrimum. 
It is said to have been a hybrid betwe'en fi. arhorcum and 
/(. raucasictuu^ iu]{\ was raised at Knaphill in 1852; it has 
pink flowers.” The plant in Mr. Huimeweirs gareh'ii is 
evidently a hyhriel of II. caurusicum, and has be'e'ii grow¬ 
ing there for fully fifty years. The original s|)e'cime'ns 
were certainly inijiorted from England and are' now 
rounel-loppe'd bushes about six feet high. For at h'asl 
thirty ye'ars the'y have' never sullered from heal or e*olel 
and have' newer faih'd to bloom freely. The' leave's show 
the influence of II. Culuwhiense but the size' of the' flow- 
('I'-cliiste'rs and the; size' of the while; flow'e'rs, w hich are 
a good (h'al like those' of //. Boulo de Neuje, point to II. 
rauraslcum. The e'arly flowers, for this is one' of the' 
('arlie'st of the hardy Bhododendrons to flower in this cli¬ 
mate, show loo the caucasirum influe'iice. lint w hale've'r

The' castor-oil jilant grow s w ilel in almost ('very part of

las now been started by a Bangkok merchant who ex- 
K'cts to harve'st about 1,000 tons ol the seeds w ith in five 
ir six months after the jilanting, which is now in pro¬
