Three New Crûg Farm Introductions

d Lilium 25/3/08 11:21 Page 1 PlantsmanThe Lilium eupetes, a new species of lily from Vietnam where it grows epiphytically on large forest trees Additional material examined: Vietnam, Lào Cai province, Nov 2006. BSWJ 11796 (Herb. BSWJ; photo WSY); floral parts from cultivated plant, Crûg Farm Plants, Oct 2007, BSWJ 11722 (WSY). At first glance appearing like Lilium arboricola Stearn which is related to the L. primulinum group, but differing in the maroon-purple petals forming an open stellate-cam- panulate flower instead of the reflex- ed apple-green petals of L. arboricola. The flowers are superficially similar to those of L. souliei and L. taliense, Photographs: Bleddyn Wynn-Jones Photographs: but these species differ in many details, including a lack of axiliary bulbils. Several other little known Lilium species, including L. puerense Three new Y.Y. Qian, L. rockii R.H. Miao and L. pyi H. Léveillé are recorded from adjacent Yunnan, but based on the information given in the account of Crûg Farm Lilium in Flora of China (Songyun & Tamura 2000) they cannot be equa- ted with these collections from Vietnam.

This mode of cultivation flowered during the dispersal is apparently unique.

The maroon flowers (top right) are usually solitary and the scaly bulb (above right) is about 2.5cm in diameter – any larger and it might have difficulty remaining on the tree. One of the most distinctive features of this new species is the aerial dispersal of the bulbils (right): they are buoyed on air currents by the dead leaf Description stellate; pedicel maroon.
