of corolla oblong obtuse, capsule almost like Ve- 

 ronica, but semi adherent, 2locular, polysperme, 

 seeds reniform. Probably a subgenus, Etoro- 

 Tis Raf. meaning eared heart, 



999. HousTONiA GENicuLATA Raf. stem geni- 

 culate 4gone assurgent, leaves subfasciculate 

 lanceolate acute, margin rough; flowers axilary 

 solitary, corolla tube filiform, limb campanulate 

 4fid — on the Wasioto hills of Kentucky, annual 

 semipedal, leaves uncial pale beneath, flowers 

 purple, calix linear, tube of corolla double of ca- 

 lix. Another subgenus by peculiar corolla, I 

 will call it GoNiOTis, I have not seen the cap- 

 sule. 



1000. HousTONiA RETICULATA Raf. stcm gen- 

 iculate 4gone erect, radical leaves petiolate 

 obovatc, on stem larger ovate acute trinerve, 

 veins reticulate, margin rough, flowers terminal 

 few corymbose, peduncles l-3flore, capsule glo- 

 bose — Alabama, annual 3 to 4 inches high, akin 

 to iJ. purpurea^ but radical leaves different and 

 smaller, on stem often uncial, calix adherent 

 with two thirds of ovary, segments linear. — A 

 var. triflora has only 3 flowers, some leaves 

 oblong mixt, either obtuse or acute. 



For other sp. of Houstonias see my mono- 

 graph of 1820, it must form several subg. or 

 even Genera. I have all our sp. H. serpylifo- 

 lia, patens, rtipestris, tenuifolia, longifolia, 

 angustif. heterophyla, puhescens, purpurea, 

 varians ^c and I may give another monograph 

 of all the SamolideSjofSamolus itself I gave one 

 in my herbarium Rafinesquianum. 



I must now conclude this Flora, although I 

 have left many families untouched in which I 

 possess many novelties ; particularly in Gratio- 

 lides, Acanthides, Personates; Scrophularia,
