liaviug no bearing on Philippine botany, is not discussed here. The 

 first paper in the volume is by W. S. SuUivant, on the mosses, this being 

 published privately in 1859, an imperial folio of 33 pages and 2G plates. 

 Three species of Philippine mosses are included, two of them with 

 descriptions, although diagnoses had previously appeared in the Proceed- 

 ings of the American Academy 3 (1857) 181-185. In 18G2, the re- 

 maindi&r of the work treating of the vascular cryptogams was published, 

 the second paper being an enumeration of the lichens l^y Edwin Tucker- 

 man, no Philippine forms being -considered. In a following paper, pages 

 155 to 192, J. W. Bailey and W. H. Harvey deal witli the algae and 

 diatoms, six species of the former being enumerated froin the Philippines, 

 of wliicli one was new, and twenty-six species of the latter, of which five 

 were new, these new species also having been previously described.^ '^I'he 

 last paper on cellular cryptogams is one on fungi by M. A. Curiiss and 

 M. J. Berkeley, pages 195 to 203, in which a single Philippine species 

 is enumerated. 



One other M'ork, although not published as a Wilkes Expedition report, 

 which treats of the botany of the expedition, is the second part of 

 Pickering's "Geographical Distribution of Animals and Plants," which 

 was published in 1876. This work was prepared for the Wilkes Expedi- 

 tion reports, and part 1 was issued as such, part 2 being published l)y 

 the author privately, after Government appropriations for printing had 

 been withdrawn. It consists of 524 pages, ending abruptly, the re- 

 mainder never having been printed. The Philippines aiv considered from 

 page 491 to the end, the work ending in the middle of the enumeration of 

 Mangsi (Philippines) plants. Here are listed approximately 500 species 

 of Philippine plants, for the most part without s])ecific identilications 

 and in many cases not even determined to the family. However, fioin 

 this list, it is evident that many species of plants wei'c collected in the 

 J'hilippincs that Avere not included in other })ublished reports, some of 

 which appear not to be represented by extant specimens. 



'^i^lie Wilkes l^'xpedition reached Manila on January 13, 1842,- and 

 lx)tanical collections were made from this date to the 2nih of the month 

 in tiie vicinity of the city and on a trip inland up I he I'jisig li'wer and 

 across Laguna de Bay. Messrs. Pickering and VAd j)nHeeded to Santa 

 Cniz and Majaijai. from the hilier i)iace ascending Mount ^fajaijai 

 (Mount Banajao) on .lannary H, while Messrs. Eich, Dana and lirackcn- 

 ridge went to the town of Hay witii tlie object of proceeding to 'I'aal 

 Volcano, but finding the latter trij) impracticalile they v/ent to l^os 

 Banos and made a partial ascent of Mount Ma(|uiling. being later joined
