31. A. SZECHUENSIS, 8p. nova. 
Plantula 30-45 mm. alta, vix supra humum, nana diffusa 
multiflora glanduloso-pubeseens. Cauliculi tenues. Folia 7-12 
mm., linearia obtusa, basi dilatata, laxe connata, parce ciliolata. 
Pedicelli axillares et terminales. Calyx basi truncatus; sepala 
21-4 mm., dense glandulosa, lanceolata acuta, margine anguste 
scariosa. Petala calyce 23-plo longiora, alba ovalia breviter 
unguieulata. Styli subulati, calycem longe superantes. 
Differs from A. longistyla in the more diffuse multifloral stems 
producing both axillary and terminal flowers, in the small sepals 
acute instead of mucronate at the apex, and the large oval petals. 
It is not very different from A. linearifolia, Franch., from which 
it is distinguished by the leaves ; though the latter is stated to 
have winged seeds, and should thus be transferred to Moehringta, 
for which therefore I propose the name of M. LINEARIFOLIA.
