somewhat broader than long, attached together along median line at apex ; side lobes 

 broader and larger than the front, overlapping them slightly ; central lobe very large, 

 triangular inflated, scarcely sculptured, apex free ascending. Reuver. 



This cone, as already mentioned, somewhat resembles that of type specimen of 

 Alnus elliptica Req., which is placed under A. glutinosa in the Kew Herbarium ; but it 

 does not agree with the common form of A. glutinosa. 



ALNUS Sp. 2. 



PI. V, figs. 2-5. 



Cone ovate*oblong, length 13 mm., breadth 10 mm.; scales few large; front and 

 side lobes nearly equal, wing4ike, free part truncate with rounded corners, irregularly 

 rugose or striate longitudinally, length and breadth about equal ; front lobes separated 

 by a U* or V*shaped gap, side lobes slightly overlapping front ones; central lobe semi* 

 circular embossed wrinkled, no free part. Seeds round or rounded*quadrilateral blunt 

 at apex, sessile attachment cordate. Approaches A. maritima. Reuver, Swalmen. 



ALNUS Sp. 3. 



PL V, figs. 6—8. 



Cone ovate or ovate*oblong, length 15 mm., greatest breadth 11 mm.; scales 

 many, blade about 4 times as broad as long, straight or slightly rounded in front, thick 

 embossed much wrinkled ; front and side lobes involute ; front lobes usually gaping, 

 side lobes overlapping them slightly; both with thin narrow rounded margins, lower 

 part thick highly sculptured ; central lobe irregular broad oval about 3 times as broad 

 as long, highly sculptured, with large central boss, bluntly pointed in front and scarcely 

 free projecting outwards. This boss is sometimes flattened into the scale and gives the 

 appearance of a large tubercle. Seed wedge*shaped ribbed longitudinally, front margin 

 concave ending in a triangular point, broadest 2 / 3 from base, base broadly truncate. 



Reuver. 



ALNUS Sp. 4. 



PL V, figs. 9—11. 



Cone oblong, length unknown, as none are complete, breadth 8 mm. ; scales few 

 small ; front and side lobes wing*like thin nearly equal, rounded in front ; side lobes 

 overlapping considerably ; central lobe round inflated wrinkled. Seeds very large, projec* 

 ting much beyond the scales, very broad apex blunt or even emarginate, base not seen. 



Reuver. 



This is a very marked species, distinguished by the great size of the seeds. These 

 are nearly as large as the whole blade of the scale, and project above it for about l /i of 

 their length, giving the appearance of two additional large lobes. 



In figs. 13 to 16 we have also shown a group of isolated seeds and scales
