II. DIAGNOSES OF NEW SPECIES AND NOTES ON 



OTHER SPERMATOPHYTES, CHIEFLY FROM 



MEXICO AND CENTRAL AMERICA. 



By J. M. GREENMAN. 



The diagnoses and notes following are the results of critical study 

 in the determination of several collections of plants which have been 

 received from time to time during the last few years at the Field Museum 

 of Natural History for identification. Particularly valuable series 

 have been received from Professor Cassiano Conzatti, from the late 

 Professor W. A. Kellerman, from Mr. Charles R. Orcutt, and from 

 the late Professor Charles R. Barnes and Dr. W. J. G. Land. These 

 collections while not containing a large percentage of new plants do 

 include many which belong to recently published and hence little- 

 known species; thus there are here introduced several brief notes, relat- 

 ing to additional localities for such species, which it is hoped may be 

 helpful in tracing their geographical distribution. 



Tradescantia angustifolia Rob. Proc. Am. Acad, xxvii. 185 (1892). 

 The type of this species is perfectly matched by specimens col- 

 lected on the Cerro de San Antonio de la Cal, State of Oaxaca, 

 Mexico, altitude 1700 m., 18 August, 1907, C. Conzatti, no. 1995 

 (hb. Field Museum). 



Ficus subrotundifolia Greenm. Proc. Am. Acad. xli. 237 (1905). 

 Specimens agreeing in all essential details with this species were 

 collected at Chichen Itza, State of Yucatan, Mexico, 28 January and 

 10 February, 1901, E. W. Goldman, no. 553 (hb. Field Museum). Dr. 

 Geo. F. Gaumer's, no. 599, coll. of 1905 from Yucatan seems also to 

 be conspecific. 



Phoradendron Robinsonii Urban, Engl. Bot. Jahrb. xxiii. Beibl. 



lvii. 4 (1897). 



This species, which was based on no. 6272 of Mr. C. G. Pringle's 

 Plantce Mexicans, has been collected at San Nicolas, Tehuacan, State 

 of Puebla, Mexico, altitude 2000 m., 22 June, 1908, C. Conzatti, no. 

 2199 (hb. Field Museum). The species is well marked and one of the 

 most attractive of the genus.
