THE present paper deals with the petaloid monocotyledons and 
plants of a few allied families recently collected in Eastern 
Equatorial Africa by the Rev. W. E. Taylor, of the Church 
Missionary Society, and Dr. J. W. Gregory, of the Geological 
Department of the British Museum, all of which will be found in 
the Herbarium of the latter institution. Of Mr. Taylor’s plants 
a large proportion were collected near Mombasa, a few at Frere- 
town and on the island itself, the rest on the Rabai Hills, a low 
range (up to 800 feet) near Mombasa, or on the Giryama and. 
Shimba hills, south of that place. A considerable number were 
gathered either at Uyui, near Tabora in Unyamwezi country, or 
on the route thence to the coast opposite Zanzibar, and a few on 
Mt. Kilimanjaro at elevations ranging from 4000 to 10,000 feet. 
Dr. Gregory collected on Mt. Kenya up to the terminal moraine 
of sheet glaciation; on the Laikipia plateau, in the Kikuyu 
country south of Kenya; and along the valley in which lie lakes 
Naivasha and Baringo. Also on the Taita mts. to 4400 feet; on 
the East Ongalea mts. due east of Kilimanjaro and 150 miles 
from Mombasa, at an elevation of 2200 feet; at Kariandusi 
(6100 feet), at the south end of Lake Elmetaita in the Masai 
country ; on the Athi plains; and at various places in the Tana 
river-basin. The plants collected between Unyamwezi and the 
coast are chiefly of tropical African atinity, serving in several 
instances to connect the Eastern and Western floras, or rather in- 
dicating the floral identity of these regions. For example, Chlo- 
rophytum andongense from Angola was found at Uyui, while two 
new Chlorophytums, a new Anthericum, and a new Lapeyrousia 
also find their nearest allies in plants collected by Welwitsch 
in Angola; a fourth Chlorophytum most nearly approaches one 
from the Cameroons. This means that nearly one-fifth of these 
plants are, in our present knowledge, of exclusively West- 
African affinity. Cyanotis hirsuta from Uyui is Abyssinian ; a 
new Eulophia and a new Urginea are of the same affinity; a
