Cycas revoluta , Belamcanda chinensis, Hemerocallis fulva, Bambusa 
Inana . Not very many of these Chinese species, which are all very 
amiliar plants in Indian gardens and shrubberies, tend to reproduce 
themselves unaided. 
As might be expected, the number of perennial species, introduced 
from Central or Western Asia or the Mediterranean littoral is 
remarkably small. A considerable number of herbaceous species 
from these regions are included among the plants sown annually 
during the cold weather, but very few of them appear as self-sown 
species and none of them do so regularly. The list is as follows: — 
* Alyssum maritimum , very occasionally spontaneous; Hibiscus 
syriacus ; Melia Azedarach, not common; Vitis vinifera , very 
occasionally planted and practically only as a curiosity ; Parkinsonia 
aculeata ; Rosa centifolia ; Lawsonia alba, as a hedge but thrives 
very indifferently ; Silybum Marianum, practically only in European 
gardens as an annual ; *Jasminum Sambac ; * Cannabis sativa, 
Cupressus sempervirens. 
The number of purposely introduced African species is not remark- 
ably large. It includes the following Hibiscus sckizopetalus , Ses?_ 
bania aegyptiaca , Bauhinia monandra , * Tamarindus indica , Poin - 
ciana regia, Colville a racemosa , Punica Gr ana turn , Vangueria edulis , 
Roupellia grata , Cryptostegia grandijlora , Jacquemontia coerulea , 
* Thunbergia alata , Ocimum viride , Meriandra bengalensis , 
* Euphorbia Tirucalli, # Borassus flabellifer, * Pennisetum borbo - 
nicum * Panicum muticum % * Panicum Jlavescens, The percentage of 
species in the list that have established themselves as an integral 
part of the flora of the Gangetic delta is unexpectedly small. 
When now we turn to the American species that have been 
deliberately introduced we find a quite different state of affairs. The 
list is here sufficiently long to render it advisable to separate 
the herbaceous species from the trees and shrubs, which are as 
follows :— •* Anona squamosa and * A. reticulata , * Bixa Orellana , 
* Malvastrum tricuspidatum and * M. spicatum , * Guazuma tomen - 
tosa , *.M alpighia coccifera , Blighia sapida , Swietenia Mahagoni 
and S.macrophylla, * Anacardium occidental, * Cassia bicapsularis, 
Ceesalpmia coriaria , * Desmanthus virgatus, * Leucaena glauca, 
* Pithecolobium dulce, * Enterolobium Saman , * Psidium Guyava, 
*Carica Papaya , * Cere us pterogonus , * Opuntia Dillenii , * H amelia 
patens , Achras Sapota , Allamanda cathartica, * Thevetia neriifolia , 
Plumeria acutifolia , Cordia Sebestena , *Lantana Camara , * Duranta 
Plumien } Bougainvillea glabra and B. spectabilis, Aniigonon lepto - 
pus , *Pedilanthus tithymaloides , *Jatropha multifida and 
Curcas , * Agave Vera Cruz .
