maica biflora, circinalis, and Dorningensis : But, 

 from the descriptions and figures of authors, espe- 

 cially of Jacquin, Swartz, and the authors of the 

 " Flora Peruviana," I without hesitation refer to 

 it the following species : E. suberectaj/^^. repens 

 Jacq. agglutinata Jacq. asperuginis Swartz, 

 torulosa Jacq. acuminata H. Peruv. laxa H. 

 Peruv. hirsuta H. Peruv. E. quinquangularis, 

 Jacq. and annularis, Linn. SuppL are probably 

 not genuine species, on account of the prominent 

 ring of the faux, and E. glandulosa H. Peruv. 

 which according to the figure has a crown of 5 

 entire laciniae and the segments of the corolla 

 equal-sided, must be excluded from this genus. 

 E. siphilitica, the specimen of which in the 

 Linnean Herbarium I have seen but not suffi- 

 ciently examined, is somewhat doubtful. E. 

 floribunda, corymbosa and spicata are removed 

 to another genus. The two remarkable species 

 of South Africa, E. bispinosa and succulenta, 

 require further examination ; for their peculiar 

 habit indicates their being a distinct genus 

 from Echites, which it would be desirable to 

 limit to the species of tropical America : hence 

 it will be necessary to re-examine certain plants 

 of India that in many respects agree with this 

 genus, especially Tsjeria-pupal-valli of Rheed,

 from Echites chiefly in having a calyx longer 

 than the tube of the corolla, in the scales sur- 

 rounding the ovarium being united, (which,
