or branch, as it were, passing through the centre, and the veins 

 all radiating from that point. In Canscora perfoliata of Lin- 

 naeus, and in C. yrandiflora, Wight (PI. Ind. Or. t. 1326), the 

 upper leaves are broad and perfoliate, the lower ones narrow and 

 free, and in other respects are quite different from ours, and which 

 cannot fail to remind the European botanist of our well-known 

 Chlora perfoliata, while the larger and orbicular leaves, sometimes 

 two to two-and-a-half inches in diameter, bring to recollection 

 those of Bupleurum rotund! folium. 



Descr. Boot annual. Plant one to two feet high, erect, 

 branched, mostly dichotomously so ; stem and branches slender, 

 quite terete, stramineous, lower ones sometimes opposite. Leaves 

 copious, not only opposite, but perfectly connate-, so that the 

 united two apparently form one exactly orbicular leaf, with the 

 stem or branch in the centre, the veins radiating from that point, 

 glaucous; the apices very obtuse, but sometimes indicated by a 

 minute point or mucro. Flowers almost as copious as are the 

 leaves, solitary, axillary, very short petiolate, perhaps the largest 

 of the genus. Calyx urceolate, ventricosc, inflated, veined, quite 

 destitute of angle or wing, four-lobed; lobes unequal, broad, 

 acute. Corolla pure white j fed* inflated below; looet obovate, 

 oblique, moderately unequal, tinged with yellow in the centre, 

 and at the base of each are two small, deep, yellow, ocellated 

 spots. Stamens four, two large and two small, inserted in the 

 faux. Ovary ovate, free ; style rather short ; stiyma rather small, 

 two-lobed.
