22 THE LATER EXTINCT FLORAS OF NORTH AMERICA. 



flowers in slender terminal aments, 2 inches long, 2 lines wide, anthers 

 few, under peltate connective scales; cones ovate or subcylindrical, com- 

 posed of rhomboidal or square peltate scales." 



We have in the specimens before us, collected by Captain Howard, 

 U. S. N., a new and strongly marked species of Sequoia, which is distin- 

 guishable at a glance from all of its known congeners by its remarkably 

 sparse, rigid, slender, and acute leaves. As usual among conifers of this 

 group, there is some diversity in -the character of the foliage, some of the 

 leaves being closely apjoressed, others longer and more spreading. In gen- 

 eral aspect the terminal branchlets resemble some of those belonging to 

 S. Couttsia Heer (Phil. Trans., Vol. CLII, Pt. II; Foss. Fl. Bovey Tracey, 

 PL LX, figs. 1, 2, 3, 6, 15, 44, 45; Fl. Foss. Arct,, Vol. I, PI. XLV, fig 

 19), but the leaves are longer and more slender. None have been observed 

 taking the squamose form exhibited by most of the foliage of S. Couttsios in 

 the illustrations given by Professor Heer. The cones, too, are longer, being 

 subcylindrical, while in S. Gouttsice they are nearly globular. One of the 

 cones is represented in fig-. 5, PI. LIII, unfortunately rather badly preserved. 

 Quite a number are associated with the leaves in the specimens before us, 

 but none more complete. The sterile aments are slender, the group of 

 anthers much less crowded than usual. On some of the branchlets the 

 foliage is more crowded and the leaves are broader than in the specimens 

 figured on PI. LIII, but this may be considered as a fair representation of 

 its average character.

Note. — In the discussion of T. occidentale Dr. Newberry says that the speci- 

 mens obtained at Birch Bay, Washington, by Professor Dana, and at Currant Creek, 

 Oregon, by Rev. Thomas Condon, are hardly to be distinguished from the living 

 T. distichum. — A. H.
