4 CIXICSSA, Linn. 



Herbs. Leaves opposite, petioled, ovate, sinuate-dentate, membranous. 

 Flowers small, white, pedicelled, in terminal and lateral peduncled racemes, 

 finally lax ; pedicels spreading, with, minute subulate (or 0) bracts at their base. 

 Calyx-tube ovoid, scarcely produced above the ovary, limb bipartite. Petals 2, 

 obcordate, 2-lobed, epigynous. Stamens 2, epigynous. Ooary inferior, 1-2- 

 celled ; style filiform, stigma capitate almost 2-lobed ; ovules attached to the 

 inner angle of the cells, solitary or rarely 2 superimposed. Fruit small, pyri- 

 form, siibcoriaceOus, indehiscent, 1-2-celled. Seeds 1 in each cell, ellipsoid. — 

 DlsTRiB. Species 2 or -3, in subarctic and cool temperate regions of the northern 

 hemisphere, extending southwards to the tropics on mountains. 



1. C. lutetiana, lann. ; DC. Prodr. iii. 63; leaves ovate-lanceolate more 

 or less pubescent not pellucid, fruit 2-3eeded narrowed at the base patent-de- 

 flexed shorter than its pedicel covered with long hooked hairs. Lamk. III. t. 

 16, fig. 1; Boiss. Fl. Orient, ii. 753. 0. repens. Wall. Cat. 6341. 



Tempbeatb Himalaya from KcMAOsr to Sikkim, alt. 7000-10,000 ft. ; Wallich, 

 Major Madden, J.D. U., T. Thomson; examples few. — Disteib. The northern hemi- 

 sphere, extending south to near the tropic of Cancer. 



Stems 1-2 ft., erect or decumbent at the base only, puberulous or pubescent. 

 Leaves 2 by 1-lJ in., long-petioled, rounded or narrowed at the base. Bracts 0. 

 Fetals white or pinkish. Pruit ^ in., obovoid, the hooked hairs usually longer than 

 half the width of the fruit. — The C. repens of Wallich agrees closely with the 

 European common type ; the stem is decumbent for a short space at the base only. 



2. Ci cordata, Royle III. t. 43 ; leaves ovate-lanceolate cordate at the 

 base more or less pubescent not peUucid, fruit 2-seeded broad-eUiptic patent- 

 deflexed little longer than broad from a broad rounded unequal base covered 

 with long hooked hairs, not shorter than its pedicel. 



Western Himalaya ; Boyle ; alt. 7000-8000 ft. ; T. Thomson. Kashmir, G. B. 

 Clarice. Simla, Jacqnemont ; Dalhousie, Chumba, alt. 7000-9000 ft. plentiful, C. B. 

 Clarke. — Disteib. Mandshuria, Japan. 



Stems 1-2 ft., stouter and more hairy than of E. httetiana, erect. Leaves 3^ by 

 2 in., sometimes larger ; petiole often 1 J in. Brads 0. Petals yellow (ex Eoyle) 

 and appear so in the dried examples. Fruit scarcely ^ in., nearly or quite as much 

 broad, the two carpels at the base generally descending unequally on the pedicel. 



3. C. alpina, Linn. ; DC. Prodr. iii. 63 ; leaves ovate glabrous or slightly 

 pubescent often pellucid, fruit l-seeded narrowed at the base shorter than its 

 pedicel, glabrous or not densely hairy. Lamk. III. t. 16, fig. 2 ; Wight III. 

 1. 101* ; Boiss. Fl. Orient, ii. 753. 0. intermedia, Wall. Cat. 6342. 



Tempehatb Himalaya, from Kashmib to Sikkim, alt. 7000-11,000 ft., not rare. 

 Khasia Mts., alt. 4500-6000 ft. Nilqhieis and Pulney Mts., alt. 7000 ft.— Disteib. 

 The Temperate Northern hemisphere. 



Erect, 6-8 in., typically nearly glabrous. Leaves |- in., and about equally broad, 

 long-petioled, rounded or cordate at the base, often deeply sinuate-toothed subangu- 

 lose, glabrous or pubescent on the nerves. Bracts minute, subulate, sometimes ob- 

 scure. Petals white. Fruit less than ^ in , obovoid, sometimes nearly glabrous, 

 sometimes with many hooked hairs, but the hairs neither so many yellow nor long as 

 commonly are those of C. hiieliana. 



'Vae. himalaica; stem taller 10-18 in., leaves much larger 1^ in. more pubescent 

 not pellucid.— In the Himalaya only ; the type of Wallich's C. intermedia. This plant 

 has (inly one seed to the fruit and differs only in trivial characters from C. alpint.
