latis longe cordato-lanceolatis puberulis v. subtus ad venas 
hispidis, bracteis ovato-lanceolatis, floris feeminei calyce tri- 
partito, laciniis latis profunde palmato-pinnatifidis.—On the 
Quorra at Addaenda, Vogel. 
Indumentum fere T. cordifolie, sed sete pauciores. ^ Petioli 
raro pollicem longi, sepius multo breviores. Folia pleraque 
3-4 poll. longa, 3-1 poll. lata, nonnulla fere semipedalia, con- 
sistentia praecedentibus firmiora. Racemi breviter peduncu- 
lati, densiflori. — Bractee serrato-ciliolatz,  feeminez more 
affinium ternz, exteriore latiore. Calycis lacinie constanter 
9, sessiles, fere ad basin divise in lacinias 11-15 lineares 
quasi digitatim dispositas, per anthesin 14 lin. longze et late, 
sub fructu hispido stellatim patentes, 3-4 lin. longze et fere 
5 lin. late, laciniis dense setosis. 
The T. pedunculata, Pal. Beauv. Fl. Ow. et Ben. t. 54, if 
correctly represented, is different from all the above in inflores-
