Morning glories... taxonomic confusion

[Guest guest]

Does anyone know if the genera Pharbitis, Ipomoea, and Rivea (and Turbina)

are all synonymous?

Bensky & Gamble list Morning Glory Seed (Qian Niu Zi) as Pharbitis. The

Western species are mainly of the Ipomoea genus (which also contains the

sweet potatoes, and, I think, Jalap [which possesses the same kind of

cathartic properties as Qian Niu Zi]). But the genus Rivea is also

mentioned (especially in discussions of lysergic acid content). Oddly, a

list of genera in the Convolvulaceae family

(http://www.fau.edu/divdept/biology/protologues.htm) doesn't even show

Pharbitis. I guess the term " morning glory " is sometimes used for all kinds

of flowers that have that general trumpety bindweed look.

When I was a teenager, everyone knew Morning Glory Seeds contained LSD

(actually d-lysergic acid amide): 5-10g of the seeds were reputed to produce

the same effect as a large dose (300 mcg) of LSD-25. But I have never heard

mention in the Chinese materia medicas of hallucinogenic effects from Qian

Niu Zi (dosed comparably) - not even in the toxicity section. Bensky

mentions that Niu Qian Zi contains lysergol - I don't know what its

relationship to LSD is. Incidentally (not that you all believe me), I'm

just curious - I'm not looking to manufacture LSD from Qian Niu Zi.

While I am far from an expert on this kind of thing, I believe that

these are not synonymous. For example, in the Chinese materia medica

Ipomoea aquatica (yöng cài zî) is considered an adulteration

and not an accepted variety of qiän niú zî
