Stem 0-2 in., grooved, thick, hollow. Radical leaves 3 in. ; pinnae 7, in. diam., 

 reticulate-nerved. Bracts like reduced leaves with narrower pinnae ; bracteoles 

 linear-obovate, toothed lobed or subpinnatifid. Umbels often subsessile ; rays 2-3 in., 

 thick, often hollow ; rays of the urn bellule often 15-20. Petals lurid green. Styles 

 very small. Fruit ^~^Q in., ovoid, subquadrate, somewhat cordate at the base, slightly 

 narrowed close under the calyx-margin which is wider than the summit of the fruit; 

 style bases depressed, inconspicuous. Carpels semi-terete; primary and secondary 

 ridges cellular, hollow, almost covering the carpel, smooth ; vittae about 8 (excluding 

 those on the commissure); carpophore 2-partite. Seed -terete, dorsally subcom- 

 pressed, slightly grooved on the inner face. 



STJBGEIT. Fentazygfon. Fruit narrowed upwards or truncate; calyx- 

 margin not prominent; ridges of the carpel 5, simple inflated rugose or 

 tubercled, secondary wanting. 



2. T. Roy lei, Lindl. in Royle III. 232 ; radical leaves 2- sub-3-pinnate

Stem 0-2 in., thick, grooved, often hollow. Eadical leaves 3 in. (including petiole), 

 oblong-lanceolate. Umbel solitary, sessile, with some of the rays (peduncles of single 

 umbels?) again umbelled; bracts leaf-like ; bracteoles 6-10, 1-2-pinnate, with lan- 

 ceolate acute ultimate segments, often white-membranous on the margin. Fruit 

 i-i in., ellipsoid, narrowed upwards ; primary ridges inflated, spongy, of cellular 

 tissue, nearly covering the carpel, glistening when very young, then rugulose, lax, 

 finally tubercled ; vittae usually 2 between the primary ridges. Seed ^-terete, dor- 

 sally subcompressed, subpentagonal.
