1958, we were able finally to introduce the tree into cul- 
tivation in easily accessible gardens. Now, with plentiful 
material and after more than a decade of cautious consid- 
eration, I still hold that we have at hand an undescribed 
genus, the diagnosis of which is presented herewith. 
Methysticodendron RP. E. Schultes gen. nov. Sol- 
lanacearum. 
Arbor. Folia ligulata. Flores solitarii, maximi, pen- 
duli. Calyx longe tubulosus, herbaceus, spathaceus. 
Corolla profundissime quinquedivisa, lobis spathulatis, 
acuminatis. Stamina tubi apicem versus affixa, filamen- 
tis robustioribus, apicem versus attenuatis et valde con- 
tortis; antherae lineares, loculis parallelis introrsum lon- 
gitudinaliter dehiscentibus. Ovula in quoque loculo nu- 
merosa, in placentis axillaria. Styli tres, liberi (sed 
aspectu singulares, mucilagine (?) cohaerentes, valde tor- 
tiles), crassiore filiformi-ligulati sed in sectione concavo- 
complanati, stigmate indiviso, clavellato-tumescenti; ex 
ovaril parte centrali duo vel tres appendices, una filifor- 
mis, stylo subsimilis sed multo brevior atque una vel duae 
ad subulas brevissimas vel bullas reductae. Fructus non 
est praesto. 
Genus apparenter Datura sectione Brugmansia satis 
affine est. 
Generis nomen Graece ‘‘arbor somnifica,’’ inter indi- 
genas usum perstringens, significat. 
Generis species typica: Methysticodendron A mesianum. 
Methysticodendron Amesianum R. L. Schiultes 
spec. nov. 
Arbor usque ad viginti quinque pedes alta, ramulis 
brevibus, dense foliatis. Folia membranacea, atroviridia, 
anguste lineari-ligulata, apice acuminata, basi sensim at- 
tenuata (saepissime sine petiolo distincto), margine vulgo
