the axis at some distance from the plumule, as in the majority of the 
Maydee. 
Andropogon saccharatus (fig. 9,10, A-O Pl. II). -The scutellum almost 
surrounds the plumule. The projection appearing in fig. 9 like an epi- 
blast is only a longitudinal section through one of the margins of the 
scutellum. The scutellum-bundle is inserted on the axis at some dis- 
tance from the plumule, while directly under the plumule two bundles 
branch off into the plumule-sheath. Fig. 10 A shows a section through 
the plumule with its plumule-sheath and bundles of the first true leaf, 
while fig. 10 B represents a section taken through the axis between the 
plumule and the insertion of the scutellum-bundle. Only one radicle 
is present with a large vessel in the center and five smaller ones 
around it in the central cylinder (fig. 10 C). There is a deep groove 
between the scutellum and the coleorhiza. 
Apluda cristata (figs. 11, 12, Pl. II). The embryo of Apluda cristata 
resembles those of the Maydew and Chloridew. There is no epiblast. 
The radicle appears as in fig. 12, with one large vessel and six smaller 
ones in the central cylinder. This arrangement continues through the 
axis until near the insertion of the scutellum, where vascular bundles 
appear. These continue through the lengthened node as far as the 
-base of the plumule, where they send off branches into the plumule- 
Sheath. The ring around the radicle in fi g. 12 represents a cross section 
through the coleorhiza. 
Tribe ZovsrkE x. 
The Zoysiew resemble on the one hand the Andropogonec, through 
Trachys, Anthephora (fig. 13 A-E, 1 Pl. II), and Perotis (fig. 15 A-D), 
and on the other hand Oryzee through Zoysia (fig. 14 A-D) and Nazia. 
Bruns, in a list of genera, represents Nazia without an epiblast, while : 
in his figures he represents it with an epiblast, both in longitudinal and 
transverse sections. The scutellum in Anthephora and Perotis i8 
inserted at some distance from the plumule, while in Zoysia it is 
inserted directly under it. The radicle of Zoysia is also curved in à 
horizontal direction like Oryza. 
Tribe TRISTEGINEJE. 
Unfortunately no representatives of this tribe could be secured. 
Bruns, however, who has investigated the fruits of Beckera and Arum- 
dinella, found them to be without an epiblast, and similar to the 
Zoysiea.
