258 ORCHIDS 



Grobya. 



Q. Amherstias (Lindl) — Flowers ochre-spotted, in pendulous 

 racemes, produced in late summer. Leaves linear, acute, sheathed. 

 P.scudo-bulbs ovate, green, terete. 1829. (B. R., t. 1740.) 



Q. galeata {Lindl.) — Flowers green, purple-spotted, produced 

 in summer ; petals oblong, obliquely rhomboid, rounded at the 

 tip, disposed into a helmet along with the dorsal sepal (whence 

 the specific name); lateral sepals deflexed, connate at base; lip 

 tripartite ; lateral segments linear, middle one cuneate-truncate, 

 with a toothed disk, warted from shining tubercles. 1836. 



QYMNADENIA. This is now included under Habenaria. 



HABENARIA. 



0\"er 400 species are known as belonging to the genus 

 Habenaria ( Willd.), of the tribe Ophrvdae ; as at pre- 

 sent understood it includes Gyiiniadciiia. They consist 

 of stove, greenhouse, or hardy terrestrial Orchids, but quite 

 an insignificant proportion figure as culti\'ated plants, 

 interesting and sometimes show}' though the)- be. In 

 habit they resemble Orcliis. Flowers spicate or racemose ; 

 se[3als sub-equal, free or cohering towards the base ; petals 

 often smaller, sometimes deeply two-lobed ; lip continuous 

 and often \ery shortly connate with the column, having a 

 short or long strap-shaped spur (hence the name, from 

 halnnia, a thong or strap), and a spreading or pendulous, 

 undivided or three- to five-lobed lamina, the lateral lobes 

 sometimes pectinate-fringed or ciliated ; column \'ery short. 

 The new introductions which in recent years have been 

 made to this some\\hat neglected genus of plants have 

 ]3ro\-ed interesting, show)', and desirable. Such kinds as 

 //. canica, H. c. nivosa, H. pnsilla, and the large pure white 

 H. Sasanihc, are suitable for stove-house culture. They 

 are deciduous and tuberous-rooted. Like most other 

 tuberous-rooted sto\'e-plants, the)' must have careful 

 attention while in the resting state, and the)' must not, 

 imder any consideration, be allowed to shrivel through 

 lack of sufficient moisture, but enough onl)' must be given 

 to maintain them in a plump condition. 



Culture. — The pots used should be as small as possible. 

 First secure the drainage by placing a large crock over the 

 liole at the base, then add sufficient broken crocks to
