shape, sometimes even smaUer, and indeed absent from some flowers, showing that 

 the spur-building mechanism was thrown out of gear, sometimes failing to work, 

 sometimes formkg a spur resembling C viride. The time of flowering, July, agrees 

 with the latter species. The lower bracts were lanceolate, just exceeding the ovary; 

 the flowers about the size of G. conopsea, pale rose and scented, but not like G. conopsea ; ' 

 the side-sepals spreading and recurved, the upper erect; the petals ovate-acute, keeled, 

 not so broad at the base as in G. conopsea, but erect and spreading, thus differmg from 

 both parents. Mile Camus has named this form var. hiloha? 



Habitat. Chalk downs, together with the parents. 



Distribution. Hants. (Winchester!); Salop! It has never been found on the 

 Continent. 



CCELOGLOSSUM VIRIDE x ORCHIS LATIFOLIA 



Orchicoeloglossum Drucei Camus 

 PL 23 C 

 Tubers not dug up, doubtless palmate as in both parents. Stem 18-21 cm., sohd. 

 Lower leaves oblong-lanceolate, rather short and broad, with faint transverse some- 

 times ringed spots in some plants and small faint sparse spots on others; upper two 

 bract-Hket narrow, acute. Spike nearly cylindrical, 5-7 cm., rather dense or some- 

 what lax at the base, with about 25 duU rose flowers. Bracts linear-lanceolate, 

 tapering to a fine point, lower longer than flowers. Sepals lanceolate, erect, spreading, 

 dull rose (in one specimen greenish in the middle and slightly spotted). Petals at 

 first connivent with upper sepal to form a hood, later nearly erect, dull rose unspotted. 

 Lip longer than sepals, oblong or slightly obovate, 3-toothed at apex with two broad 

 longitudinal stripes of continuous or interrupted rose colour on a whitish ground 

 occupying most of the lip. Spur short, barely half as long as ovary, rather thick, 

 rounded at tip. Pollinia brownish, viscid glands not enclosed in a pouch. 



The parentage of C. viride is clearly shown by the habit, low stature, short broad 

 leaves, oblong 3-toothed lip, often with side-teeth curved forward, and short rather 

 sack-like spur. That of 0. latijolia is suggested by the ring-spotted or spotted leaves, 

 rather dark-coloured flowers, erect spotted sepals, small mid-lobe of the lip, and by 

 the spur, longer and less saccate than in Cdoglossum. 



The plant is evidently a hybrid of Caloglossum viride with a spotted-leaved orchid, 

 and the only two such present with it being 0. latijolia and 0. maculata, the second 

 parent must be one of these. Two hybrids of C. viride with 0. maculata were found 

 in the locality {vide PI. 22), and in both the resemblance to 0. maculata was at once
