172 Dr Graham's Description of' New or Rare Plants. 



3. C. arachnoidea-plantaginea ; raised from seed of C. plantaginea, pro- 



duced by the pollen of C. arachnoidea. 



This plant is almost identical in appearance with the last, the parents be- 

 ing only transposed. The flower is rather smaller, its colours darker, 

 more decided, more speckled, and, on the whole, certainly handsomer. 



4. C. corymhosa-Fothergillu ; raised from seed of C. Fothergillii, produced 



by the pollen of C. corymhosa. 



! This plant being produced by a cross between species much more dissimi- 

 lar, is quite unlike any of the others, has little of the family features of 

 either of its parents, and apparently the delicate health of a badly orga- 

 nized mule. The leaves are like those of C. Fothergillii., but they are 

 more numerous, and extend farther, upon a more robust stem. The 

 form of the flowers considerably resembles those of C. Fothergillii, but 

 the}' are larger, and yellow. Its habit is such that I thought it was 

 probably a mule between C. Fothergillii and C. integrifolia, before I was 

 informed by Mr Morrison of its origin. 



Eutoca sericea. 



E. sericea; suberecta, foliis utrinque sericeis pinnatifidis, laciniis estror- 

 sum incisis, superioribus linearibus integerrimis ; ovulis placentae sin- 

 gulte numerosis, multis abortientibus; staminibus corolla triplo Ion- 

 gioribus. 



Description Root perennial. Stem (10 inches high) herbaceous, sub- 

 erect, angular, red, hoary, leafy, branched at the bottom. Leaves very 

 numerous, spreading in a stellate manner from the crown of the root 

 and lower part of the stem, or scattered along the stem, smaller and 

 more entire upwards, the lower with their petioles 5 inches long, the 

 ujjper linear, entire, and about 1 inch long, pinnatifid, covered on both 

 sides with subadpressed white. hairs, channelled, subdecurrent along the 

 petiole ; segments incised on their outer edges, and each section has a 

 strong central nerve, prominent below, and channelled above. Spike ter- 

 minal, solitary, compound, dense, about half the height of the whole 

 plant. Spikelets erect, gradually elongating, hairy. Flowers erect on 

 the upper side of the spikelets, expanding from below upwards. Calyx 

 5-parted, segments linear, nearly smooth on the inner side, on tlie outer, 

 covered like tlie pedicels with long, spreading, somewhat matted white 

 hairs. Corolla (about 3 lines long, 4^ across), inferior, subcampanulate, 

 bluish purple, equal to the length of the calyx, segments 3-nerved, blunt, 

 entire, smootli, paler towards the base, and there on the inside some- 

 what hairy, and each having two overlapping membranous, nectariferous 

 wings. Stameiis 5, nearly thrice the length of the corolla, connected with 

 its base, and alternating with its segments; filaments straight, distant, 

 tapering, purple, slightly hairy at their origin, every where else smooth ; 

 anthers vellow, placed transversely, attached by their middle, bilobular, 

 lobes somewhat crescent-shaped, furrowed in tlie centre. Germen green, 

 ovate, subcompressed. covered with loose white simple hairs, unilocular; 

 style erect, subangular, jiurple, nearly as long as the stamens, bifid at 

 its apex ; stigmas 2, small, 3-anglcd, green. Ovules, attached to each 

 parietal receptacle, numerous. Seeds ovate, com])ressed into a keel along 

 one side, dark brown, and covci'ed with many round depressions, placed 

 in longitudinal rows. 



Tliis prettv and perfectly hardy alpine was raised at the Botanic Garden, 

 Kdiuburgli, in \H2i>, ivom seeds collected in Captain Franklin's second 

 expedition to the arctic coasts of America, and jn-eseiited by Mr Drum- 

 mond. It tlowercd for the first time in spring 1823. This year it is 

 much stronger, and was in full flower in the open border in May.
