568 REPORT OF THE HARVARD AFRICAN EXPEDITION 
In the vicinity of Boa and Suehn, coffee is cultivated rather extensively 
and it is quite possible that most of the coffee that is exported from Liberia 
is raised in this region. Cacao is also grown, but more abundantly near Suehn. 
The apocynaceous Callichilia subsessilis(?) appears in the second growth as a 
beautiful erect bush that produces fairly large, cream-colored flowers. Myri- 
anthus arboreus and Dichapetalum Linderi grow in the secondary forest. The 
latter species has been described by Hutchinson and Dalziel! from material 
collected by the writer. An epiphytic member of the Piperaceae with fleshy 
leaves that are scarcely more than an inch long, and with flowers in small yel- 
low-green spikes, is used by the Vai in an attempt to cure fits. To accomplish 
this end, the leaves of this plant are cooked with rice and administered to the 
patient. 
The last species to be remarked upon is Mussaenda macrosepala(?). It is a 
tall, straggling shrub that is conspicuous because of the densely hirsute cymes 
of large orange-yellow flowers and the prominent, enlarged and light greenish- 
yellow, leaf-like sepals. This species appears to be confined to a zone extend- 
ing fifteen to twenty miles back from the coast. | 
In the above account of the botanical phase of the Harvard African Ex- 
pedition to Liberia, only a partial picture of the flora of that country can be 
given since species in such large families as the Rubiaceae, Apocynaceae, Maran- 
taceae, Zingiberaceae, Commelinaceae and others have not as yet been deter- 
mined. For this reason, the results of collecting are expressed in the following 
table in numbers gathered:

In conclusion, the writer wishes to express his gratitude to Dr.-R. P. Strong, 
the director of the Expedition, for the privilege of serving as botanist; to Mr. 
Hill and his associates at Kew for their kindness in communicating the deter- 
minations of a portion of the flowering plants that were collected; to Professor 
Oakes Ames for a partial determination of the species of orchids; to Dr. Joseph 
Bequaert for his invaluable assistance in the field; and to Dr. George T. Moore, 
Director of the Missouri Botanical Garden, who by arranging a year’s leave 
of absence, made it possible for the writer to participate in the Expedition.
