94 THE FLORA OF THE DAKOTA GROUP. 



undoubted cliaraoters of a seed of the LauiincfC, like those of J^aurus, ('in- 

 namomum, Sassafras, etc. Its upper part, f)'"" hjug- and 3.5""" broad, 

 rounded at apex, is supported upon a short pedicel 2'""' long, which, enlaro-ed 

 at its top, forms a support to the base of the fruit and is marked like it 1))' 

 corresponding vascular scars. The seed is easily separated from the embed- 

 ding matter and also from its sup})ort. 



It is comparable to the seeds of Cinnamoimim pohimorplmm (Al. Braun) 

 Heer(Engelhardt in Nova Acta, vol. 43, PI. xiii, Fig. 11 ; PI. xvii, Figs. 7-11).

LAURUS TELIFORMIS, Sp, JIOV. 



PI. L, Fig. 9. 



Leaf small, rigid, subcoriaceous, lanceolate-acuminate, decurring to a 

 thick, curved petiole, entire; midrib narrow, rigid; secondaries thin, very 

 distinct, camptodrome, incumbent, quite near the border; the lowest pair 

 basilar, distant from the upper one at a more acute angle of divergence ; the 

 upper gradually less distant and more open ; areolation very small, 2)uncti- 

 form. 



This fine leaf is of thick texture, G.o*"" long, including the thick curved 

 petiole, which is over 1.5"™ long. It is only 12™°' broad at the middle, 

 whence it is rapidly naiTowed to a sliarply pointed apex and very gradually 

 tapers to the petiole, decurring to it at the base. It has eight pairs of sec- 

 ondaries, the lowest diverging from the base of the midrib at an angle of 20°; 

 those above gradually less distant from each other under an angle of diver- 

 gence of 30°, the uppermost of 50°. 



The secondaries are thin, but passing throixgh or cutting the epidennis 

 of the leaf; all simple, following the borders in festoons. The character of 

 the nervation is that of various species of Laurus of the Tertiary, being 

 especially like that of L. dcj-matopIiijUon Weber (Ettingshausen in Flora v. 

 Bilin, pt. 2, p. 7, PI. xxxi, Fig. 8), L. .mperha Sap. (Etudes, vol. 2, PI. vii, 

 Fig. 4), L. resurgens Sap. (ibid.. Fig. 9), etc. 



Habitat: Kansas. 



Laubus Knowltoni, sp. nov. 

 PI. L, Fig. 4. 



Leaf large, linear, lanceolate, thick,- coriaceous, with smooth surface; 

 midrib stout; secondaries irregular in distance, thick, divei'ging about 40°
