NATIVE BRITISH ORCHIDACE^ 



tiny leaf-spots, hollow stem, purple bracts and red-purple flowers. A specimen a 

 Thorenc, above Grasse, was 70 cm. tall ! (spike 7 cm.), stem solid except for a central 

 pin-hole, leaf-spots large, transverse, faint, ringed; flowers large, bright ^ed-viole , 

 side-lobes broad, toothed, mid-lobe pronounced, acute, spur short truncate (PL 48). 

 Another specimen had densely spotted leaves with a tendency to form rmged spots, 

 long bracts and bright red-lilac flowers. One on the Col de Granier above Chambery 

 had bright violet flowers, larger than in either parent, lip broader than long, with 

 rhomboidal side-lobes and short triangular mid-lobe, and spur longer than ovary. 

 At Gryon, Switzerland, June 26th, 1925, a specimen had a spike 17 cm. long, large 

 flowers (PL 50, fig. 19) and thick cylindrical spur 10 mm. long. Some of the above 

 had transverse bands of darker green on the stem.

Townsend (F/. Hampshire, p. 409) says: "Some plants have spur of laUjoha, but 

 solid stem^ and spreading leaves of maculata, with the lower bracts longer than the 

 flowers". White (F/. Bristol, p. 556) says: "Mr Fry observes: This plant has the 

 leaves of maculata but approaches latifolia in its hollow stem, much broader and more 

 deeply cleft labeUum, with the lateral lobes ultimately reflexed, and markings con- 

 fined to the centre, and in its much thicker spur, longer and stouter germen more 

 reflexed lateral sepals, and much larger and more conspicuous bracts. ... Similar 

 hybrids are on record from Devon".
