Mr. McDonough inrespone to your posting with respect to Arisaema yunnanense and some possible ambiguity over colours, etc. I have the first edition of Mr & Mrs Gusman's Arisaema monograph so looked up the description for you on page 392, as follows:- A. yunnanense Buchet in Lecomte, Notul. Syst. 1. (12) p.367 (1911) Deciduous up to 50 cms tall and 25 cm wide. Subglobuse tuber 1.5 - 4.0 cm wide Roots few slightly woody and branched. Pseudostem to 35 cm long, Green Cataphylls 2 or 3, 2-30 cm long, thin and brown striped Petiole 10-20 cm long, pale green or purplish Leaf. one trifoliate held at 80 degrees Leaflets three, broadly lanceolate plain green above, sometimes variegated, underside glaucus, apex acute or acuminate, margins entire. Central leaflet is the largest segment, 10-25 cm long, 2-12 cm wide, subsessile or with a petiolule to 1.5 cm, Lateral leaflets smaller, slightly asymmetric, sessile. Flower emerges after the leaf unfolds, flowering at leaf level or above. Petiole 2 12-30 cm long, green or pinkish, Spathe tube cylindrical 3-6 cm long, 1-3 cm wide, colour yellowish green, white striped, yellow when fading. If you need any more detail extracted, there's about as much again, feel free to get in touch. As we progress the Arisaema collection here, several taxa have proved to be hardy than has been suggested, coping down to - 15 C to - 25 C for prolonged periods it is maybe a question, as with Lilium etc, that perfect drainage is of paramount importance. I try two or three new taxa most years and had few losses so far. I hope the above helps, best wishes, Iain.
