 with a distinctly gonolobus-like habit ; but on account of the tubular- 

 camjjanulate corolla, the elongated gynostegium, and the pendulous or 

 somewhat oblique pollen-masses the plant is jilaced rather under the 

 genus Lachnostoma. 



Ipomcea barbatisepala. Gray, Syn. Fl. ii. pt. 1, 212. To tliis 

 species are to be referred specimens collected in the State of Oaxaca, 

 Mexico, at an altitude of 1650 m., December, 1900, Conzatti S^ Gonzalez.,

 Gr.), agree in all essential details with the original of the above species. 

 The specimens from Yantepec Valley, however, show a considerable 

 variation in the foliage, particularly as to the breadth of the leaf-lobes,
