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 in 

 the Naturhistorisches Hof museum in 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 (uos. 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 Tribuhis terrestris^ L., Grotalaria incana, L., and 

 Rhynchosia Senna, Gill. I have little doubt that the first of these is 

 what Andersson has called 2\ sen'ceus, a plant which is too near to 

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

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

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

 ner's plants was Tillandsia insularis, Mez.

1 With the collaboration of Professor H. Pittier, the author is preparing a cata- 

 logue to bring togetlier the now scattered references to the tlora of Cocos Island, 

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

 In this subsequent paper the species here listed will be treated in greater detail.
