Thymelcsa hirsuta, Linn. Mount Hor and Petra ; Bir es Seb4. 



T. ? sp. Tell Abu Hareireh. 



LORANTHACE^. 



Viscum cruciatum, Sieb. Near Jerusalem. Very like our mistletoe, 

 except in the berries, which are red. 



Loranthus acacice, Zucc. Abundant on acacias and nubk (Zizyphus), 

 in a grove several miles in length on the east side of the 'Arabah, about 

 fifteen miles north of 'Akabah. In Wady Ghuweir, on tamarisk and 

 nubk ; plentiful in Ghor el Feifeh and Gh6r es Safieh and near Jericho, 

 on nubk. This species may be dependent on the visits of the sunbird for 

 the fertilization of its flowers. Specimens of this bird (Cinnyris Oseee) 

 were obtained with their long bills dusted with the pollen of the tubular 

 flowers, which the bill is well fitted to probe. I may add that they usually 

 occur together, as at Jericho, Gh6r es Safieh, and near El Tiba. The 

 berries are red, cup-shaped and soft, with a single large hard seed. 



EUPHORBIACE^. 



*Euphorbia csgyptiaca, Boiss. Gh6r es Safieh. A tropical African 

 species, ranging from Egypt, Nubia and Abyssinia, to the Cape de Verdes, 

 and Senegal on the west, and Northern India on the east. An addition 

 to the flora of Palestine. 



E. cornuta, Pers. Frequent in Sinai, especially on the western side.
