CONVOLVULACEAE. — PORANA 361 



According to C B. Clarke P. truncata Kurz (in Jour. Bot. XI. 136 [1873]) " is 

 intermediate between that species and P. malabarica." It was collected in Burma 

 (Pegu and Martaban), and I have not seen a specimen. Kurz mentions Griffith's 

 No. 5876 from East Bengal as related to his species. I have a specimen of this 

 before me, bearing only fruits which are very similar to those of P. malabarica, but 

 the sepals are more ovate, rather acute at the apex, and more contracted at the base 

 the fruits appear to be more globular.

This is a widely distributed half-shrubby or almost herbaceous climber, the 

 " Snow-creeper " of the English, according to Clarke, " one of the most beautiful 

 of Indian plants." The type was collected in Nepal.

A very distinct species, the tubepf the flowers of which is a little enlarged at the 

 point of insertion of the stamens, which are in one row.

 Darjeeling at 5-6000 feet elevation, on metamorphic rocks," October 1868, S. 

 Kurz (type, ex Kurz). 



According to Clarke " this differs from P. grandifiora in the shallowly cordate 

 leaves, the remarkable bracts, the color of the flowers, and the exceedingly narrow 

 fruit-sepals." The author and Clarke do not say anything about the stamens and 

 the gynaeccum, and I have not seen a specimen. This species needs further 

 observation.
