Socotra. Near Galonsir. B.C.S. n. 178. 



Distrib. Endemic. 



Another plant I have referred to this genus. It has a very strong plantag- 

 ineoid habit. Its inferior ovary relegates it to Rubiaceae, and it appears to fall 

 into this genus. The fruit is however very peculiar, being quite flattened and 

 with an empty vertex, which is bifid and elongated so as to form a couple of 

 short projections beyond the persistent calyx.
