NO. 1 TAYLOR : PACIFIC MARINE ALGAE 1 7 



meliads, ferns, and orchids; and the writer had for the first time the 

 pleasure of seeing here in the wild state the Butterfly-Orchid (Oncidium 

 Kraemerianum) , as well as a Polystacha and a Brassavola. The dampness 

 of the woods rendered this a splendid place for collecting ferns, and num- 

 erous kinds were seen, including in particular several exceedingly delicate 

 and beautiful Filmy-Ferns (Trichomanes). 



Bahi'a Cabita23 



The visit to Ba, Cabita will always be memorable to the writer as his 

 first good opportunity to collect in a wet tropical forest. The bay seemed 

 a promising one for algae in every respect, until close examination showed 

 that the rocks had practically no large algal growth upon them. They 

 seemed well placed, but except for a fair growth of small filamentous 

 species and a very sparse development of encrusting types there was noth- 

 ing to be had between tidemarks. In the splash zone at and above high 

 tide mark there was, however, a little growth of Bostrychia. 



The great attraction of this place lay in its wet, very dark forest. A 

 small, rapid stream enabled some of us to penetrate the country for quite 

 a little distance. On the rocks in the stream a small mosslike alga was 

 quite common. While it is Rhodophycean, probably undescribed and not 

 distantly related to Batrachosperrnum, it is interesting enough to deserve 

 consideration apart from the marine algae, and will be held for a later 

 report. That, however, at the time produced but minor enthusiasm. Here 

 the writer first saw growing wild the famous Filmy-Ferns (Tricho- 

 manes), notable as having the leaf blade (except for the veins) trans- 

 lucent and but one cell thick. Able to survive only where growing in a 

 nearly saturated atmosphere, these here covered dead sticks and the lower 

 trunks of small trees with a deep green mantle. The light was so feeble 

 that the attempts made to secure photographs in the woods were complete 

 failures; although the writer was well familiar with plant photography 

 in the woods, he greatly overestimated the light intensity. The list of fern 

 genera noted here is too long to introduce into a report on algae. Only 

 two kinds of orchids were noticed, but of one, a particularly interesting 

 Lady-slipper (Phragmopedhun), there was a very good clump. 



IsLA Gorgona, Valle^^ 



This beautiful, rocky, wooded island was one of the most attractive 

 spots visited. The high slopes, with trees of different foliage shades, were 

 wooded down to the rocks of the shore line ; and beautiful, delicate water-
