8 ANGIOSPERMAE— DICOTYLEDON ES 



doptera. Rhopalocera : 4. Vanessa urticae L., skg. E. Thysanoptera. 5. 

 Thrips, freq., skg. Scott-Elliott (Dumfriesshire), 2 humble-bees, a short-tongued bee, 

 3 Muscids, several Dolichopodids, a Lepidopterid, and the beetle Meligethes (' Flora 

 of Dumfriesshire,' p. no). Lindman (Dovrefjeld), on the var. arctica (with a corolla- 

 tube up to 30 mm. long), a humble-bee, a beetle, a micro-Lepidopterid, and several 

 flies. 



1695. C. groenlandica Berl. — Kolderup and Rosenvinge consider that this 

 reputed species is a variety of C. rotundifolia, belonging to the same series as arclica 

 (Abromeit, ' Bot. Ergeb. von Drygalski's Gronlandsexped.,' pp. 62-3). 



1696. C. caespitosa Scop. (Kirchner, Jahreshefte Ver. Natk., liii, 1897, 

 p. 210.) — The flowers of this species are arranged in racemes or panicles. The 

 corolla is bell-shaped and elongated (14-16 mm. long), broadest in the middle, and 

 somewhat contracted under the lobes. It is bright-violet in colour with a reddish 

 tinge, and marked internally with a distinct network of veins. 



1697. C. pulla L. (Kirchner, op. cit.) — The large terminal flowers of this 

 species are pendulous on short peduncles. The tube of the dark-blue bell-shaped 

 corolla is 16 mm. long, while the lobes are 6 mm. in length, spreading, and tolerably 

 straight. The entrance of the flower is 12 mm. broad. The style is 12 mm. long, 

 and its branches do not recurve to form more than a semicircle, so that they do not 

 reach the region to which pollen adheres. 



1698. C. excisa Schleich. (Kirchner, op. cit.) — In this species the stem is 

 erect, and the nodding flowers project horizontally from its end. The corolla is much 

 smaller than that of C. pulla, and the curved shape of its incisions is characteristic. 



1699. C. cenisia L. (Kirchner, op. cit., p. 201.) — Kirchner gives the following 

 description of the flower mechanism of this species from the high Alps. — The flowers 

 are solitary at the ends of short procumbent branches, and are directed vertically or 

 obliquely upwards. The bright-blue corolla has a funnel-shaped tube 4 mm. long, 

 and spreading apically reflexed lobes 10 mm. in length. The diameter of the flower 

 above is 15-20 mm. The bright-blue style (10 mm. long) stands vertically in the 

 middle of the flower, and projects somewhat beyond its entrance. At a later stage 

 of anthesis its end divides into three (sometimes four) bright-yellow branches. The 

 little drops of nectar secreted on the top of the ovary are completely covered by the 

 broadened bluish-white bases of the filaments, which are fringed with woolly hairs. 

 Automatic self-pollination does not take place, for though the stylar branches curve 

 away from one another they do not become reflexed. 



1700. C. pyramidalis L. — Kerner states that in the final stage of anthesis 

 the stylar branches of this species curl back i-ii turns, so as to render automatic 

 self-pollination possible. 



1701. C. lingulata Waldst. et Kit. ( = C. capitata Sims). (Kirchner, op. cit., 

 p. 208.) — In this species the narrow funnel-shaped corolla is 35-40 mm. long, and 

 the style does not project from it. The aid of particularly long-tongued insects 

 appears to be necessary for pollination. 



1702. C. Scheuchzeri Vill. — The corolla of this species is 25-30 mm. long. 

 Visitors. — The following were recorded by the observers, and for the localities 



stated. —
