others, among the garden plants of Egypt ; and was besides seen by

The Cissus rotundifolia was probably known in Egypt during the 

 Early Muslim Period. — The plant was seen by Delile in gardens at 

 Cairo; and by Forskal, on the mountains of Yemen. 



The Euphorbia tliymifolia, an Indian weed, was probably known in 

 Egypt during the Early Muslim Period. — It is figured by Plukenet ; 

 and was seen by Forskal in the mountain region of Yemen ; and by 

 Delile, in Upper Egypt and at Damietta. 



The Hibiscus trionum, a Tropical weed, was probably known in 

 Egypt during the Early Muslim Period. — The plant is figured by 

 Matthioli, Lobel, and Parkinson ; and was seen by Sibthorp in Greece 

 and Cyprus ; and by Forskal and Delile in Egypt. 



The Sida spinosa, another Tropical weed, was probably known in 

 Egypt during the Early Muslim Period. — It was seen by Forskal and 

 Delile, growing spontaneously around Cairo. 



The Sida mutica, also a Tropical weed, was probably known in Egypt 

 during the Early Muslim Period. — It was seen by Delile, in gardens at 

 Rosetta; and again, in Nubia, where it has a native name. 



The Achyranthes argentea, another Tropical weed, was probably 

 known in Egypt during the Early Muslim Period. — It was seen by 

 Hasselquist in Palestine; by Sibthorp in Sicily; and by Forskal, 

 Delile, and others, growing spontaneously around Cairo. 



Other Tropical weeds now common in Egypt, were probably intro- 

 duced during or before the Early Muslim Period : as, the Aerva tomen- 

 tosa, seen by Forskal and Delile, in Yemen, in Upper Egypt, and in 

 gardens at Cairo ; the Celosia margaritacea, seen by Delile at Cairo ; 

 and the Alternanthera sessilis, seen by Hasselquist at Jerusalem, and 

 by Forskal and Delile at Rosetta. 



Seeds of an undetermined species of Chamceriphis, were found by 

 Delile in the drug shops of Cairo : the same description of seeds may 

 have been imported during the Early Muslim Period. 



The Impatiens balsamina was probably known in Egypt during the 

 Early Muslim Period. — The plant is figured by Fuchsius and by Mat- 

 thioli ; is enumerated by Clot-Bey and Figari, as cultivated in the

 of Bombay.
