fruited. Watercress grows abundantly from cuttings, but I failed 
to raise it from seed. Dandelion on Penang Hib at one time 
established itself on the banks at an altitude of 2,000 feet from 
cultivated forms in the vegetable garden there. But instead o 
retain in s’ the original broad-leaved form it developed into a narrow- 
leaved form which resembled that of the New Guinea Mountains. 
It seems to have now quite disappeared. 
Many years ago I found Poa annua and Cerastium abundant as 
weeds 0/ the Thaiping Hills about 5,000 feet but mey seemed to 
have disappeared later. 
Cultivated ornamental plants of European origin do not do as well 
as those of American origin. Violets m tfe y Pains produce 
few flowers and those nearly all cleistogamous well-shaped open 
flowers ale scarce. They produce capsules but never establ.sh 
themselves. 
Double Roses constantly show signs of reversion as ^ “nsider- 
able number of the central petals revert to stamens. The floors 
become smaller also, and I have never seen ripe fruit. The single 
Roses have always failed and the Sweetbriar also soon perished. 
Pansies Lilies of the valley, Forget-me-not flower often once and then 
die. Poppies, Sweet-peas, Stocks and such flowers gerrmnate. grow 
for a short time producing only leaves, and eventually die without 
flowering. Sweet-peas and Nasturtiums often grow to a consider- 
able height with extremely weak stems and flaccid leaves, le ore 
dving With comparatively few exceptions the ordinary Enjish 
n flowers either behave like this or, if they do flower and 
feeu as Zinnias, Marigolds, Sunflowers, they commence to deteriorate 
after the first generation, the colours becoming dull, the stems 
weak flowers small and seed scanty. The highly cultivated forms 
doubles, etc., throw back to single ones and often go back to the 
duller colouring of the wild one. 
When one looks at the list of the Flora of Europe one notices 
what very few plants are common to this region and that, 
is a small number of plants introduced and established in southern 
Italy Sicily, etc., brought in with rice probably, such as 
tubescens, * Fimbristylis squarrosus , Imperata cylmdrica, p e J a ™ 
ilauca Panicum colonun. A few more distinctly established and 
of wider area: Cyperus rotundas, Sarpusmucronatus,^ aim II
