The flowers in C. subulata, Roth, and C. striata, Kunth, are always blue as far 
as known. The name ©. subaurantiaca, Hochst., appears to have been given by 
Hochst. in the herbarium (not from any field note by the collector, Schimper) ; and 
Hasskar! suggests that it refers to the yellow colour of the dried plant, not to that of 
the flower, the colour of which is unknown in C. subaurantiaca.

Welwitsch has carefully noted the colour of the flower in all these numbers—as 
“yellow,” “light yellow,” or “ brownish-yellow.” Except, however, in the colour of 
the flower, I can discover no difference between this plant and typical C, subulata, Roth. 
7. CG. angustissima, K. Schum. in Engl. Pfl. Ost-Afr. C. 134. 
Annual. Stems slender, 16 in. high. Leaves 7 by } in., very narrowly 
linear. Spathes solitary, less than } in. long, villous. Flowers deep 
blue ; otherwise as C. swbulata, Roth.

No example seen ; but the three subjoined plants agree with the description in 
the long linear leaves, and small spathes shaggy with white multicellular hairs.

Probably annual. Stems 1 ft. high, slender. Leaves up to 5 by } in., 
elongate-lanceolate. Spathes less than } in. long, glabrous. Flowers 
blue. Seeds trigonous, nearly flat, conspicuously 3-lobed. Very near 
C. subulata, Roth, but excellently separated by the 3-lobed seeds.

Separate the species excellently from any other species of Commelina , it is difficult 
to imagine how they would pack into the 5-seeded 3-celled capsule of the Sect. Hu-
