PLANTS FROM ALASKA. 171 



known leaves of Ginkgo digitata. They closely resemble a large Ginkgo 

 leaf found in the Jurassic (Lower Oolite) flora of Douglas County, Oreg. 

 This form has been described by me as G. Huttoni viagnifolia (supra, 

 p. 171). The leaves now in question resemble the Oregon plant in their 

 great size, in the irregular width of the divisions of the leaf, in the remote- 

 ness of the nerves, and in their great strength. The size of some of 

 these Alaskan leaves makes it improbable that they belong to G. digitata. 

 One of the fragments, which has much of the summit of the leaf 

 missing, is still 5 cm. long, while a spread of 7 cm. is shown on one very 

 imperfect specimen. The nerves of these are more remote than those 

 of G. digitata and much stronger. 



PL XLIV, Fig. 7, gives a fragment of one of these leaves which 

 is apparently divided into only two very wide lobes. But even this is 

 not certainly an original partition of the leaf. It has much the appear- 

 ance of an accidental division. Some idea of the size of the leaf may 

 be obtained from it. Another specimen is given in Fig. 8. In this the 

 divisions are clearlj^ accidental. In it a portion of a stout petiole is 

 shown. As, however, the material is very imperfect, the true place of 

 the forms can not be positively determined.

n The four specimens thus named by Professor Lesquereux were collected by Mr. Woolfe but were either 

 received in advance of the main collection or otherwise became separated from it and were sent to Lesquereux 

 and described by him a year earlier than the rest. They were overlooked in sending the collections to Professor 

 Fontaine and not included in his report. They were subsequently sent to him, and in his letter dated March 

 17, 1902, he says of them: "The specimens sent last do not call for any modification of my report, as they are 

 all Nageiopsis longifolia." The best specimen is shown in PI. XLV, Fig. 5. — L. F. W. 



'' Although Professor Fontaine says that Lesquereux did not mention the specimens of this species in Mr 

 Woolte's collection, nevertheless he labeled the one having Lesquereux's No. 911 Nageiopsis longifolia. This 

 was one of those that Lesquereux referred to Baiera pahnata Heer. It is here represented in PI. XLV, Fig. 2. —
