APPENDIX. 
Tribe 3. Duboisiee. Corolla with a tube either sone) 
gated and ventricose above, or short and rotate, 
with a 5-lobed border, the lobes being diversely 
volutive in zstivation : 5 equal stamens or 4 di- 
dynamous with the rudiment of a fifth ; anthers 
rounded, cordate, always extrorse, either 2- | Dubdoisia, 
celled, with the cells confluent at the apex, or 
165 
unilocular with a hippocrepiform line of de- r Aathocercis, 
hiscence, and gaping transversely as in Verbas- | Anthotroche. 
cum: ovarium 2-locular, with numerous ovules 
affixed to thickened placentz adnate to the dis- 
sepiment: fruit either baccate or capsular, 2- 
valved, with septicidal dehiscence: terete em- 
bryo in albumen, slightly curved. 
Tribe 4. Schizanthee. Corolla deeply cleft into alge | 
ral irregular divisions, with a somewhat reci- 
procative zstivation : stamens 5, of which 3 are 
sterile ; style erect, with a small fistulose stigma, Ockicuisthes: 
slightly swollen below, its contracted entire mar- 
gin filled with a globose viscous gland: capsule 
2-celled, 4-valved, seeds with a terete hemicy- 
clically arcuate embryo. 
Tribe 5. Salpiglossidee. Corolla more or less ven- 
tricose above, sometimes contracted in the 
mouth, the border being divided into 5 nearly 
equal regular segments, one of them always 
somewhat larger and more erect, their zstiva- 
tion being reciprocative (see p. 172): stamens 4, 
didynamous, sometimes with the rudiment of a

Salpiglossis, 
Pteroglossis, 
fifth ; anthers 2-lobed, lobes divaricate at base, >Leptoglossis, 
connected at apex by intervening filament, one 
of the lobes being sometimes reduced to a small 
lateral dehiscent gland: style winged at its apex 
or expanded into a remarkable tongue-shaped 
process, which is stigmatose at its emargina- 
ture: fruit capsular, 2-locular, 2-valved : embryo 
slightly curved, much more so in Salpiglossis. J 
Tribe 6. Petuniee. Corolla with an elongated tube, 
sometimes hypocrateriform, seldom with the ru-. 
diment of a palate, the border being divided 
into 5 nearly equal, rounded and emarginated 
lobes, their wstivation in Petunia being replica- 
tive (see p. 173), in Nierembergia, replicative 
at the base of the lobes, with a perfectly quin- 
cuncial imbrication at their summits ; stamens 5, r 
one of which is shorter, 2 longest; anthers 2- | 
Petunia, 
lobed, divaricate at base, without connective : 
stigma expanded into a remarkably tongue- 
shaped form, emarginate at its apex, in Nierem- | 
bergia embracing the anthers : capsule and seed 
as in Salpiglossidea. :
