Iw the present paper are characterized upwards of 150 Dicotyle- 
dons of the Gamopetalous series of natural orders, gathered in 
Madagasear by recent English collectors, especially by the Rev. 
R. Baron, F.L.S., of the London Missionary Society. The most 
interesting is Schismatoclada, a new genus of Rubiacez allied to 
Cinchona. The other new genera are :— Tetraspidium, of the group 
of semiparasitie Serophulariacez such as Pedicularis and Melam- 
pyrum (which turn completely black in drying), remarkable for its 
four shield-shaped one-celled anthers; Forsythiopsis, an erect 
shrubby Acanthaceous genus with flowers like Forsythia and 
leaves not fully developed till after the flowers fade; and Mona- 
chochlamys, another genus of Acanthacew, allied to Mendoncia 
and Thunbergia, with numerous small flowers each contained in a 
persistent spathaceous bract like the hood of a Franciscan monk. 
Of representatives of well-known European genera, the present 
collection contains two species of Anagallis nearly allied to 
A. tenella, 2 Ajugas, a Salvia, 2 Micromerias, 3 species of Stachys, 
5 Senecios, 3 Cynoglossums, and a Lysimachia. The genera re- 
presented most largely are Danais, Vernonia, Helichrysum, Gert- 
nera, Clerodendron, and Hypoestes. There is a single species of 
the beautiful Acanthaceous genus Strodilanthes, represented in 
India by above 100 species. There is anew Vinca allied to V. rosea. 
Of endemic genera known previously in the island, we have new 
species of Aspilia, Epallage, and Oncostemon. Of Cape types the 
principal are a Lightfootia, a Halleria, an Alectra, and two heaths 
of the genus Philippia.
