Re: More on Arisaema erubescens

From: grsjr at juno.com (George R Stilwell, Jr.) on 1997.02.27 at 02:18:52(439) Peter, Very interesting. Thanks for sharing the references with us. I do have a translation of the Key from Flora of China done at the National Arboretum. It does identify A. erubescens but does not even mention A. consanguineum. Hopefully the descriptive portion of the document does do that, but I do not have a translation of that. I do have a partial translation, not in computer form, and will search that. The section of the key on A. erubescens shows: Arisaema Sect. 13 Sinarisaema 1. Spathe throat margin entire. 2. Appendix apex glabrous. 3. Leaflets 14, undulate-margined; appendix thick-clavate, narrowed to base, upper part to 1 cm thick. 70. A. undulatum Krause 3. Leaflets entire. +More 4. Leaves 2. 5. Leaflets 9, oblanceolate; spathe purple with white striae, blade with linear cauda to 12 cm long; appendix thin, 7 cm x 1 mm. 71. A. oblanceolatum Kitamura 5. Leaflets 11, linear-lanceolate; spathe green with white striae, blade with linear cauda 4.0-4.5 cm x 5-6 mm, female appendix with numerous sterile flowers. 72. A. biradiatifoliatum Kitamura 4 Leaf 1. 6. Petiole longer than leaf blade; appendix more or less with sterile flowers. 7. Spathe green with white striae; leaflets 7-13. 8. Appendix thin, 4-5 cm x 1 mm, slightly recurved, sparsely covered with sterile flowers below. 73. A. formosanum Hayata 8. Appendix thicker, 5-6 cm x 2-4 mm, middle and lower parts with obtuse sterile flowers to 7 mm long. 74. A. kelung-insulare Hay. 7. Spathe green or purple, with or without white striae; appendix narrowed toward base and apex, 2-4 cm long, 2.5-5.0 mm thick in middle, lower part with sterile flowers; leaflets few or more. 75. A. erubescens (Wall.) Schott 6. Petiole shorter than blade; leaflets 13, 30 x 6-7 (-10) cm. 76. A. brevipes Engl. 2. Appendix apex ciliate or rugose. 9. Appendix clavate, stipitate, 2.2-6.0 cm x 5-9 mm, apex densely echinate for more than 0.7 mm. 78. A. echinatum (Wall.) Schott 9.
