| Abstract:
The review puts forward and extends the chemo-dahlgrenogram of the genus Papaver over Papavereae. — Tertiary Cathcartia owns watery latex as Romneya (Palaeoaster’s sister), but is evoluted by sole sand-like crystals in seeds’ coats. On the other hand, Cathcartia, that synthesizes indenobenzoazepine alkaloids, differs substantially from Meconopsis. Therefore Cathcartia is an independent entity representing the starting-point for Papavereae. — Meconopsis cambrica Vig. is missing Meconopsis constituents mentioned before, but synthesizes armepavine derivative aporphines, as well as meconic acid and nudicaulin (stated at Papaver sections, but being unproved at Meconopsis taxa). Therefore the species belongs to Papaver genus, and its original name Papaver cambricum Linnaeus is effective again. — Meconopsis polycarpic (sometimes monocarpic) species of ser. Simplicifoliae accumulate retroprotoberberines, but ser. Grandes only berberine. Monocarpic species of Aculeatae and Robustae are characterized by isopavines, orientaline derivative aporphines and harmane alkaloids. Monocarpic life span of Meconopsis taxa is analogous with the biennial Papaver sect. Meconidium. — Separation of the Californian, annual Stylomecon heterophylla with phthalideisoquinoline alkaloid content from the Asian genus Meconopsis is also proved, alike to some annual or biennial Papaver taxa. — Roemeria species with aporphines and protoberberines are joined to Papaver section Argemonidium. Chemism of Roemeria refracta with rhoeadanes, promorphinanes is more similar to Papaver genus, in contrast to R. hybrida synthesizing spirocyclic-coupled proaporphines, unique at Papavereae. — The previous Papaver chemo-dahlgrenogram must be changed by detaching sect. Pseudopilosa (oxoprotopines, phthalideisoquinoline, aporphines and thebaine derived from orientaline) from the previously defined sect. Pilosa (aporphines and promorphinanes derived from reticuline). — The chemo-dahlgrenogram of the tribe Papavereae was constructed according to above data. | |
