The Spurred Orchids, part 2 Edgar T. Wherry Some authors split the genus Habe- naria of Willdenow into a number of smaller genera, but the plants are just as difficult to cultivate whether classed in large or small groups, and for sim- plicity they will here be kept together. Northern Rein-orchids, Habenaria bracteata, H. dilatata, H, hookeri, H. hyperborea, H. macrophylla, H. obtiisata, H. orbictilata. These species apparently survived glaciation in the higher Appalachians, and after the retreat of the ice spread far and wide in northern lands. They are all about alike in preferring cool, moderately acid, porous, humus-rich, moist soil. Their fleshy foliage is ex- ceedingly susceptible to attack by slugs, rot-inducing fungi, and other pests, and attempts to cultivate them are rarely if ever successful, except in habitats essentially identical with their natural ones. Southern Rein-orchids, Habenaria clavellata, H. flava. Ranging as they do from the Gulf of Mexico to the Great Lakes and to Newfoundland and Nova Scotia, re- spectively, these species are evidently adapted to a wide range of climatic conditions. They are also not par- ticular as to soil acidity, although most frequent in rather strongly acid hu- mus. If a moist shady place is avail- able they can probably be cultivated after a fashion, but their flowers are too inconspicuous to be worthy of much eflFort. Frog-arrow Orchids, Habenaria in- tegra, H. n'wea. Intensely acid, moist pinelands and *Contribution from the Botanical Laboratory and Morris Arboretum of the University of Pennsylvania.. Edgar T. Wherry Habenaria ciliaris in a weedy meadow in piedmont Virginia grassy meadows are the preferred habitats of these southern orchids. While most abundant in the Gulf states, they range north to New Jer- sey, so m
