The most often recommended book on the genus is "The Genus Arisaema" by G & L Gusman. The problem is that this is out of print and second hand copies command a rather high price. The 1st. Edition, 2003, ISBN 390414491X, is available at Amazon for ~£140 to £400 but is advertised at €39.00 from Koeltz Botanical Books. The expanded, 2nd. edition, 2006, ISBN 0881928399, can be bought on Amazon for ~£1200.

Another worthy, (and also out of print), book which covers just the Himalayan species is "Himalayan Cobra-Lilies (Arisaema): Their botany and culture" by Udai C. Pradhan. I bought a copy of the 1st. edition, 1990, with B&W illustrations, ISBN 8185423008, for £20 at an eBay auction. The 2nd. edition, 1997, with colour photos, ISBN 8185423040, can be bought on Amazon from £250 to £840.
