 Smilax ornata Lemaire. Zarzaparilla. (Plate 33.) 



Foliage specimens of officinal sarsaparilla were collected near Izabal, and a 

 flowering specimen has recently been sent me from the same locality by Senor M. 

 Hernandez C The species is said to flower in Guatemala from January to 

 March; the root is collected from January to April, and is not valuable after- 

 wards. The roots are done up in small bundles, tied with pieces of the stem, 

 and dried for a week over a slow fire. They are then tied up in bundles of 100 

 to 150 pounds, and shipped to New York, where they bring about one cent a 

 pound. The plant grows in swamps, and has a thick four-angled stem with 

 strong retrorsely curved spines, and large ovate leaves sparsely spiny on the 

 nerves beneath.
