with albuminous seeds the first leaf mostly has the form and 

 structure of the normal leaves, and has a distinct petiole and 

 blade developed. This fact has been pointed out by Engler,* 

 but it seems, as if it had been overlooked, that the. seed of 

 our plant is exalbuminous, as Engler describes it under the 

 tribes Peltandreae as having *' Scmina albuminosa. 



But, besides the development of the first leaf, we see 

 also the second one (L- in Fig. 144), and further, that the 

 primary root has been almost surpassed, in regard to growth, 

 by the lowest pair of secondary roots (r^). The primary ^. 



root, of which the direction seems to be almost horizontal in 

 contrast to the others, which usually grow immediately

downward, has now attained its final length, while the second- 

 ary roots (r\ r2 and^ in Fig. 145) are rapidly growing out. 

 We see further, in Fig. 145, that, besides the above-mentioned . 



two pairs of secondary roots (r^ and r-), another one has 



been developed (r^) below the primary one. In this same 

 state (Fig. 145) the leaf has come out (L-) showing the shape 

 of the first one (L^), but is almost twice its length, and sur- 

 rounds the base of the third one (L^), which again assumes 

 the same form. We now have on this germinating plantlet 

 three leaves, all of which are approximately scale-like, or at 

 least with the blade entirely wanting, and very different from 

 the normal, arrow-shaped leaves. There is, however, between 

 these two forms a sort of transition, since, as shown in Figs. 

 147 and 148 (L- and L-^ which are the first leaves after the 

 scale-like ones), they have a blade, which is ovate-lanceolate

and tapering at both ends. This kind of leaves, which precede 

 the normal ones, may appear sooner or later, /. e., either fol- 

 lowing immediately upon the first scale-like leaf (P in Figs. 

 147 and 148) or being preceded by even three of that kind, 

 as the specimen shows (Fig. 145). The further development 

 of the roots is shown in the Figs. 147 and 148, and we see 

 in all four pairs of secondary roots on both sides of the front 

 part of the young plant, and two others, the one above, the
