crimson, but changing through orange to pale yellow as the 

 blossoms unfold. 



Botanists, unacquainted with this plant except from La 

 Llave's good description, have referred it to the genus Qua- 

 moclit, with which it doubtless corresponds in many respects, 

 especially in the structure of the ovary and stigma. But in 

 that genus, that is to say in the legitimate species, of which 

 the old Ipomsea Quamoclit must be regarded as the type, the 

 flowers are arranged in the manner common to the majority 

 of the order, and the limb of the corolla is as usual flat when 

 expanded. Here, on the contrary, we have quite a peculiar 

 inflorescence, and the limb of the corolla inflated into an 

 oblonof 5-cornered bao", the base of which is so much thrust 

 inwards by the tube as to hide that part from mimediate 

 view. Considering what the characters are on which the 

 recognized genera of the Convolvulaceous order are esta- 

 blished, it certainly appears to me that this genus Mina must 

 be recognized.
