though where it is not covered with vegetation other than lichens it shows still 

 all its characteristics. 



Beyond Auahi, with its fifty species of trees, is open, flat, rough country with 

 a few scattered trees of Xanthoxylum, the last stragglers from the dry forest 

 which have ventured out into the open, or perhaps are the survivors of an old 

 forest previously existing in this locality. Close to it lies the Kaupo Gap, or 

 southern outlet of Haleakala crater, beyond which seems to be a semi-wet dis- 

 trict, followed immediately by the rain forest.
