 pedunculare, intermingled with which there is an equally 

 dwarfed Alpine Draba. The only umbelliferous plants 

 growing in the low grounds within the tropics observed by 

 us in the New Continent were two species of Hydrocotyle 

 (H. umbellata and H. leptostachya) between Havannah and 

 Batabano ; therefore at the extreme limits of the torrid Zone.

The group of arborescent grasses which Kunth, in his 

 able treatise on the plants collected by Bonpland and my- 

 self, has combined under the name of Bambusaceas, is among 

 the most beautiful adornments of the tropical world. 

 (Bambu, also called Mambu, is a word in the Malay 

 language, but appears according to Buschmann to be of 

 doubtful origin, as the usual Malay expression is buluh, in 

 Java and Madagascar wuluh, voulu.'i The number of genera 

 and species which form this group has been extraordinarily 

 augmented by the zeal of botanists. It is now recognised 

 that the genus Bambusa is entirely wanting in the New 

 Continent, to which on the other hand Guadua, from 50 to 

 60 French or about 53 to 64 English feet high, discovered 

 by us, and Chusquea, exclusively belong ; that Arundinaria 

 (Rich) is common to both continents, although the species 

 are different ; that Bambusa and Beesha (Eheed.) are 

 found in India and the Indian Archipelago, and Nastus in 

 the Island of Bourbon, and in Madagascar. With the ex- 

 ception of the tall-climbing Chusquea the forms which have 

 been named may be said to replace each other morpholo-
