1. Omphalodes aliena, A. Gr. MSS. in hb. Kew. 
Foliis cordiformibus, inflorescentia laxo-racemosa ebracteata. 
Herba annua, 6-8 poll. alta, longe strigoso-pilosa, caulibus erectis vel adscendentibus, gracillimis, basi 
tantum foliosis. Folia tenuia, longe petiolata, cordiformia, brevissime abrupteque acuminata,

4-5 lineas diametro, laxe pseudo-racemosi, ebracteati, pedicellis filiformibus usque ad 6 lineas 
longis; calycis segmenta lanceolato-oblonga, obtusa, extus densissime longeque albo-strigosa ; 
corolla subrotata, squamis crassiusculis papillosis instructa. Nucule, ut videtur, dimorphe ;

circumalatz, subplane, glabra, ala crenata, plana, tenui, subscariosa.

We think there can be no doubt that the nucules of this species are dimorphic, the 
Wing in a few of the lower ones being thickened, hispid, and turned back, and in the 
rest thin, glabrous, and flat. 
2. Omphalodes cardiophylla, A. Gr. MSS. in hb. Kew. 
Folis cordiformibus, floribus omnibus axillaribus. 
Herba annua, 3-4 poll. alta, hispidulo-pilosa, ramis gracillimis, undique foliosis. Folia tenuia, 
radicalia longe petiolata, omnia cordiformia, gradatim acuminata, lamina maxima 1 poll. longa, 
radicalium petiolis gracilibus usque ad 3 poll. longis, caulinorum petiolis 4-12 lineas longis. 
Flores 3-4 lineas diametro, axillares, solitarii, pedicellis quam folia brevioribus ; calycis segmenta 
ovato-oblonga, obtusa, extus strigillosa; corolla breviter tubulosa, squamis crassiusculis 
papillosis instructa. Nucule pateriformes, circumalate, mature puberule ; ala vix incrassata, 
retroflexa, dentata, dentibus angustis longiusculis acutis.
