DR. DICKIE ON AECTIC SPECIES OF ALGiE, 235 



This is the dicliotomous palm of Eastern Africa common to the 

 maritime region. There are two varieties, the 



1st with stem 30 feet high, many times divided ; fruit smaller 

 and less flattened than in the second: observed on the Eovuma, 

 between eight and twelve miles from the sea-coast. The 



2nd is a smaller palm, seldom divided more than once, and 

 often a bush with very short stem; the fruit much flattened at 

 the end, and of a deep brown colour. It grows abundantly at 

 the Zambesi mouth.

This palm is not found on the sea-coast ; two hundred miles 

 up the Zambesi it is common, also at the south end of Nyassa, 

 and on the river Shire. On the hills it is less frequent. The 

 stem is 20 to 30 feet high, more or less flexuose or erect. Fronds 

 large, the ligule well marked and nearly equal on both sides. 

 Fruit ovate or oblong, larger than that of -ff. coriacea. Elephants 

 sometimes swallow it ; but by men it is seldom eaten,

It waa 



seen by us on the low rocky islands above the Victoria Falls of 

 the Zambesi, and is well represented in an oil painting of that 

 scene by Thomas Baines. 



From other IlyphcerKB it is known by its loftier stem, which is 

 often swollen in the middle like that of Borassus — and by its 

 spherical fruit surrounded by a considerable quantity of farina- 

 ceous matter, and larger than that of either of the preceding. 



I believe that this species extends south to the Lake JN"gami. 

 By the Makololo it is named " Mokolwane."
