longitudinal slits confluent at the top, so as to represent a pore. OVARY 1 -celled, of 

 2 connate carpels, placentation parietal; style simple ; stigma obtuse ; ovules numerous, 

 anatropous, horizontal. CAPSULE with 2 valves placentiferous on their edges. SEEDS

The genus Ramondia, which constitutes this little family, is represented by a Pyrenean plant 

 formerly referred to J'erbascum (V. Myconi). It is distinguished from Solaneai by its one-celled fruit, 

 its anatropous ovules and straight embryo; from Scropftulnrineee by its regular pentandrous ilower and its 

 1-celled ovary; and from Gemcracccp. by its regular isostemonous corolla and the placentiferous dehis- 

 ceuce of the capsule.

, A.-L. de Jussieu. BIGNONIACE^, Br.) 



COROLLA hypogynous, monopetalous, anisostemonous, more or less irregular, aestiva- 

 tion imbricate. STAMENS generally 4, didynamous, inserted on the corolla. OVARY 

 I-2-celled, base girt by a glandular disk; OVULES usually horizontal, anatropous, in- 

 serted near the edge of the septum, or parietal. CAPSULE generally 2-valved. SEEDS 

 transverse, compressed, winged. EMBRYO straight, exalbuminous ; RADICLE usually 

 centrifugal. 



Woody PLANTS, often climbing or twining, very rarely herbaceous (Incarvillea, 

 Tourretia}. LEAVES generally opposite, very often compound, sometimes terminating 

 in a tendril, exstipulate. FLOWERS 5 , in racemed or spiked cymes. CALYX mono- 

 sepalons, 5-fid or -toothed, or 2-partite or -labiate, or with the limb nearly entire,
