ramisque alternisy floribus laxe spicatis, in characteribus omnino 
cum Bignoniaceis convenit, inter quas recte ordinanda, tamen 
habitu discrepat quod magis ad Scrophularinas referrens ab his 
defectu albuminis differt. 
1. T. grand^rum, foliis elongato-lanceolatis acuminatis ener- 
viis, umbella multiflora, laciniis calycinis ovatis, corollae lobis 
omnibus rutundatis subaequalibus, stylo exserto. 
Incarvillea parasitica, Roxh. Coromand. t. 291. 
Crescit supra arhores Montium prope Sylhet, Indiae Orienta- 
lis.— IFttZZicA. bw. 
2. T. parmjlorum^ foliis ellipticis acuminatis nervosis, umbella 
pauciflora, laciniis calycinis linearibus, corollae lobis superiori- 
bus brevioribus acutiusculis, stylo incluso. 
Crescit secus truncos arborum in montosis Nepaliae irferioris.

Species a praecedente distinctissima : floribus triple minoribus, 
laciniis calycis linearibus, lobis corollae 2 superioribus multo bre- 
vioribus acutiusculis, foliis duplo latioribus brevioribusque ner- 
vosis. 
These two species, although perfectly distinct, have been sent 
in the recent collections from India indiscriminately under the 
name of Incarvillea parasitica^ Roxb. Both species are para- 
sitical shrubs, with showy flowers, resembling in habit some spe- 
cies of Loranihus. The flowers of T. grandifiorum are not in- 
ferior to those of Digitalis purpurea.
