Among the grasses in the Rijks-Herbarium I found an undeterminated Panicum, received from the British Museum, collected in the Bombay Presidency by Mr. YOUNG. This plant is very interesting as it belongs to a small group of about 18 species in general appearance very similar to the genus Brachiaria as accepted by American authors. ¹) In the genus Brachiaria the spikelets are placed with the first glume towards the axis (adaxial), but in the group forming the genus Urochloa, the first glume is turned away from the rhachis (spikelets abaxial). Nearly all the species of Urochloa have a very obtuse apex of the fertile valve, ending in a fine mucro.
