small patches of luma forest, the last ones in this direction, and on the almost 

 vertical face of Cerro Tres Puntas is a large carpet of Ochagavia elegans, the 

 finest growth of this lithophyte found on the island, but from here to Punta 

 de la Isla nothing but the poorest Avena <^^r/^<7/c?-grass-land is to be seen. Bahia 

 del Padre receives frequent visits from the langust-fishers and as a consequence 

 is full of weeds, inuch more numerous than the scattered native litoral plants — 

 with the exception of Salicomia per-uiriaiia, which is abundant (PI. 102). From 

 the narrow, gently sloping beach a short climb leads to the Puente, a flat tuff 

 bed with a field of mobile sand (St. 52). 



From Cabo Guasaballena along the south side of the island 

 to Cerro Negro. Little can be added to what has been said already about 

 this forbidding coast. The elevated summit ridge is, as it were, supported by a 

 series of buttresses, separated by shallow ravines, where stunted trees, shrubs 

 and ferns, among which the large leaves of Gumiera are conspicuous, cling to 

 the rock. The high ridge is drenched in rain, and from the crest cascades tumble 

 down into the abyss. The dome of El Yunque dominates the scenery, but it is 

 often hidden from sight by fog (Fig. 2). At the foot of El Yunque, Cerro Negro 

 rises like a bastion (PI. 92, alt. about 180 m, one reading only). West of this 

 hill stretches the Piano del Yunque; from here toward Punta Larga is pasture- 

 land, where Acaena argejitea and numerous other weeds are widely spread.
