development of the calyx as the fruit matures in the last 4 species (and perhaps 
with them S. quadrisulcus should also be associated), would almost seem to 
warrant the retention of the genus Pachycalyx, Klotzsch, for them, 
I. Calyx very distinctly 4- (rarely 3-) angled, with 
or without a more or less distinct midrib on the flat 
or grooved faces between the angles : 
* Leaves 3-nate; bracts 3, coming away with the 
calyx ; calyx-teeth opposite the angles of the 
tube; ovary minutely puberulous at the top, 
2-celled : 
Calyx-teeth as long as the tube; stigma 
minute, peltate, shortly crater-like ... (1) carneus. 
Calyx-teeth 4-3 as long as the tube; stigma 
simple or obconically thickened : 
Leaves glabrous or rarely thinly pubes- 
cent on the back; corolla contracted 
at the basal third : 
Young leaves ciliate and together 
with the bracts and calyx-teeth 
usually tipped with a few hairs... (3) barbiger. 
Young leaves not ciliate, and as 
wellas the bracts and calyx-teeth 
without a tuft of hairs at their 
tips san ‘as see Ks 
Leaves finely and shortly pubescent or 
puberulous all over; corolla slightly 
narrowed just at the base... ... (4) pubescens. 
* Leaves 4d-uate; calyx-teeth alternating with 
the angles of the tube; ovary glabrous : 
+ Stigma simple or very slightly thickened : 
Bracts 3, coming away with the calyx ; 
calyx-tube glabrous : 
Ovary 2-celled, not 4-angled ; calyx- 
teeth not ciliate ... ae aoe 
Ovary 4-celled, with 4 much com- 
pressed angles ; calyx-teeth ciliate (6) piquetbergensis. 
Bract solitary (in 7, S. glabellus, 8, 
S. depressus, and 10, 8. swhmuticus, 
sometimes accompanied by 2 very 
small Jateral bracts,) and coming 
away with the calyx or 0 except the 
floral leaves, which remain on the 
axis; ovary 2- rarely 3-celled : 
{ Calyx-tube glabrous or only pubes- 
cent down the middle of the 
grooves or on the ribs between 
the angles, often ciliate on the 
teeth : 
§ Leaves linear or linear-lan- 
ceolate; calyx-oblong = or 
slightly obconic - oblong, ; 
scarcely or but slightly nar- 
rowed downwards : 
Leaves widely spreading ; 
corolla 11 lin. long,

narrowed within the }-3

Leaves spreading to erectly 
imbricate ; corolla 14-2
