FLORA OF THE GALAPAGOS ISLANDS. 261 



Vienna, a manuscript list of the specimens of plants collected on the 

 Galapagos Islands in 1872 by Dr. Steiudachner and now deposited ia 

 the Naturhistorisches Hofmuseum iu Vienna. These plants were gath- 

 ered rather as souvenirs of a peculiar flora than as scientific specimens, 

 and many are fragmentary. The list at hand includes the pteridophytes 

 (nos. 21 and 22) and spermatophytes (nos. 23 to 116). The first twenty 

 numbers seem to have been applied to thallophytes and bryophytes, but 

 these are not listed. The only plants mentioned which are not included 

 in the above flora are Trihulns terrestris, L., Crotalaria incana, L., and 

 lihynchosia Senna, Gill. I liave little doubt that the first of these is 

 what Andersson has called 2\ sericeus, a plant which is too near to 

 T. terrestris for very satisfactory distinction. Dr. Zuhlbruchner writes 

 that the labels furnish no data as to the particular islands upon which 

 the plants were collected. The only new species among Dr. Steindach- 

 uer's plants was Tillundsia insularis, Mez.

1 With the collaboration of Professor IL Pittier, tiie author is preparing a cata- 

 logue to bring togetiier the now scattered references to the flora of Cocos Island, 

 and unite with them the data derived from recent and very interesting collections. 

 In tiiis subsequent paper tlie species here listed will be treated in greater detail.
