Abstract
AN important feature in the revision prepared by Dr. C. B. Robinson of Philippine Urticaceæ, is the discussion of generic limits and relationships. A new genus, Elatostematoides, is proposed for certain species previously referred to Elatostema or Pellionia, and another genus, Astrothalamus, allied to Maoutia. Under Laportea, a genus of notoriety on account of its stinging hairs, it is mentioned that the hairs are siliceous, and may contain formic and acetic acids; also that prompt relief is afforded by ammonia or carbonate of soda. Many new species are differentiated, notably nine for Laportea and twenty for Elatostema. The first part only of the article appears in the concluding number of the fifth botanical volume of The Philippine Journal of Science.
