5. CRUCIFERJE. 
funicle filiform. (In S. thalianum tlie pod is quadrangular 
and the valves keeled with the side nerves fine and obsolete : 
thus approaching Erysimum.') 
Tribe in. BRASSICEJE. 
Seeds often globose. Cotyledons incumbent conduplicate 
folded together longitudinally in the middle, radicle dorsal 
embraced in their fold. 
8. Brassica. Pod linear or oblong ; valves convex with a 
single straight dorsal nerve ; lateral nerves none or repre- 
sented by a few anastomosing veins. Seeds globose in a 
single row in each cell. 
9. Sinapis. Pod linear or oblong ; valves convex with 3 or 
5 straight prominent strong nerves. Seeds globose in a 
single row in each cell. 
10. Sinapidendron. Pod linear slender curved or wavy, 
round or slightly quadrangular subtorulose ; valves convex 
with a single strong straight dorsal nerve and a few lateral 
longitudinal anastomosing veins. Seeds subangular oval 
or oblong in a single row in each cell and partly imbedded 
in the somewhat spongy dissepiment. 
11. Eruca. Pod oblong short; valves convex with a single 
subprominent dorsal nerve. Seeds globose in a double row 
in each cell. 
Suborder II. SILICULOS^E LATISEPTiE. 
Pouch short oval orbicular or globose, compressed from back 
to front, opening with 2 broad valves, 2-celled ; partition or dis- 
sepiment nearly or quite as broad as the pouch in its broadest 
diameter. 
Tribe IV. ALYSSINEsE. 
Seeds compressed. Cotyledons flat accumbent. 
12. Koniga. Pouch oval or roundish compressed, each cell 
1-2-seeded. Filaments simple not winged or toothed. 
Ilypogynous glands 8. Carpophore none. 
13. Dr aba. Pouch oblong or elliptic slightly convex or 
tumid. Seeds many in each cell, not margined, in 2 rows. 
Filaments simple. 
Suborder III. SILICULOS.E AN GU STISEPT/E. 
Pouch short, compressed laterally, opening (except in Senc- 
biera) with 2 narrow generally boat-shapea valves keeled or
