KNowi.TON.T DESCRIPTION OF STECrES. 27 



l)een called G. enropsens^ Sequoia Couttsm^ etc., l)ut we have not a suffi- 

 cient amount of authentic material to enal)le us to settle the question. 



The sin<j'le specimen with its counterpart (U. S. Nat. Mus., No. ^(U(>), 

 referred by Lesquereux to Sequoia ]\f<>rden,skloldil^ is undou])tedly the 

 same as what is here called (j/i//>fostro7>H-<< Ungeri. 



Loealtty. — Van Horn's ranch, about Vl miles west of Mount Vernon, 

 (trant County, Oregon. Collected by Maj. Charles E. Px'ndire (U. S. 

 Nat. Mus., Nos. 2480, 2610) and by Merriam's expedition of 1900 (Mus. 

 Univ. Cal., Nos. SG8, S72-882). 



Taxodium distictium miocenum lleer. 



The collections embrace a dozen or more branchlets that I am con- 

 strained to refer to this form. They do not agree perfectly with cer- 

 tain Hg-ures of this species, but the diU'erences are slight, and they had 

 best be placed here. Unless material is very perfectly preserved it is 

 difficult to determine the exact manner of the insertion of the lea\es, 

 and such is the case with these specimens. 



Locality. — Mascall beds, Van Ilorn's ranch, Oregon. Collected by 

 Maj. (Miarles E. Bendire (U. S. Nat. Mus., No. 26U) and by Merriam's 

 expedition of 11>00 (Mus. Univ. Cal., No. 8T8a). 



Taxodium, male aments of. 



PI. I, figs. 4, 6. 



In the material from the Mascall beds are two specimens, both of 

 which are here figured, that appear to represent the male aments of 

 Taxodium. They are long, slender, and clustered, with the aments 

 on short lateral spurs. They are hardly to be distinguished from 

 the aments of the living* Ta'xodiimi distichum., and in all probability 

 belonged to T. disticham miocenum., which is not uncommon in these 

 beds. 



Local itij. — Mascall beds, Van Horn's ranch, Oregon. Larger 

 specimen (tig. 4) collected by Merriam's expedition of 1900 (type in 

 Mus. Univ. Cal., No. 889). Other example (fig. 6) collected by 

 Knowlton and Merriam, July, 1901 (U. S. Nat. Mus., No. 8551).
