H 



HABENARIA (Greek, a rein or strap; referring to 

 the shape of parts of the flower). Orchiddcese, tribe 

 Ophrydese. Rein Orchis. Terrestrial leafy herbs, 

 sometimes grown in bog -gardens and naturahzed in 

 moist places. 



Tubers usually undivided, rarely lobed: fis. in ter- 

 minal racemes or spikes, rarely sohtary ; sepals subequal, 

 free or cohering at base, erect or spreading; petals 

 usually smaller, often 2-lobed; lip spreading or drooping, 

 long- or short-spurred at base, its blade entire or 3-5- 

 fid.; column very short, sessile; rostellum usually 1- 

 toothed or lobed; glands naked; anther-cells parallel 

 or divergent: caps, ovoid or oblong, erect. The lateral 

 lobes are sometimes fringed, giving the 

 fl. a graceful appearance. ^^pecies about 

 400, very widely distributed in temper- 

 ate and tropical regions. 



Few species of Habenaria axe of much 

 horticultural importance, especially in 

 this country. Some of the exotic kinds 

 enjoy some favor as stove plants in 

 England, while there are a number of 

 hardy North American species which can 

 be recommended for outdoor cultiva- 

 tion in boggy places. H. Susanna, H. 

 carnea, H. militaris and other East 

 Indian species are best grown in a moder- 

 ately wann house, needing good light 

 and a fair amount of water. It is recom- 

 mended to repot them after the resting 

 season in a compost of peat, moss, loam 

 and crock dust, with the tuber resting 

 upon the crocked-up bottom of the pot 

 and the growing point just beneath the 

 Boil. They should then be given a good 

 supply of water until after flowering. 

 These habenarias are much hke bletia 

 in their requirements. The most popular 

 species at present seem to he H. ciliaris, 

 H. fimbriata and H. psycodes, but these 

 give a very imperfect conception of the 

 beauties of the genus, although in the 

 opinion of some persons, H. ciliaris is 

 the showiest orchid in temperate North America 

 native species are procurable through collectors and 

 dealers in native plants: foreign species through Dutch 

 bulb-growers; and H. radiata through dealers in 

 Japanese plants.
