Encephalartos.| | CxXX. CYCADACE® (Prain). 347 
stipe slender, usually angular. Ovules sessile, ovoid, inverted. Seeds 
ellipsoid or oblong, usually slightly angular by compression, at length 
protruding between the mature scales.—Shrubs or small, rarely 
medium trees with a simple or casually branched globose, fusiform 
or cylindric trunk clothed with coriaceous scales and the woody 
bases of the petioles. Leaves in terminal plumes or crowns, linear- 
oblong, erect or the outer ascending, pinnate; pinnules diminishing 
from the middle downwards, linear-lanceolate or lanceolate or ovate- 
or oblong-lanceolate, longitudinally many-nerved, the nerves close- 
set, tip pungent, margin (in the tropical species) spinulose-toothed, 
very rarely casually entire, usually slightly revolute, straight in bud ; 
lower often reduced to spines. 
Species about 17; seven within the tropics, the others in South Africa. 
A species of Encephalartos, E. horridus, Lehm. (Pugill. vi. 14) [Zamia horrida, 
Jacq. (Fragm. 27, tt. 27, 28)] is said by A. de Candolle (Prodr. xvi. ii. 532), to 
be a native of Tropical Africa. This does not appear to be the case ; Jacquin 
received his original plant from an unspecified locality 100 miles inland from 
the south coast; the only localities for which we have records of the collection 
of uncultivated specimens are in Cape Colony. According to Sim (For. Fl. 
Port. E. Africa, 109) one or more species of Encephalartos occur in M’Chopes and 
elsewhere in Portuguese East Africa ; one, wild in the vicinity, is planted for 
ornament in the square at Quissiqui. These species are known in the language 
of Zuvalla as Impanga or Mwanga. No specimens have been seen; the species 
in question are stated to occur only to the south of Inhambane and therefore 
beyond the area here dealt with. 
Leaves thinly coriaceous, bright green; pinnules 
linear-lanceolate, slightly falcate, acutely acuminate, 
base subequally long-cuneate, margin about 4- 
toothed throughout on either edge; stem very
