 6:618. Gn. 16:534; 29, p. 382: 45, p. 503; 50, p. 373; 

 54, p. 467: 76, p. 183; 79, p. 124. J.H. III. 32:209: 

 50:407. J.F. 1:SO. In China this species is represented 

 by forms regarded as distinct species, as in Xos. 120 

 and 121. Var. grandifldra, Pax, is a culture-form with 

 large fls. in a more open head, the fls. being very short- 

 pedicelled. B.M. 6916 B. 



120. pseudocapitata, Ward. A Chinese (Yunnan) 

 representative of P. capitata, with smaller trusses of 

 purple fis.; bracts cut. Intro. 1911. 



121. sphaerocephala, Balf. f. & Forr. Much like P. 

 capitata, with small globular heads, the fls. purplish 

 inside, not annulate, bracts fimbriate: delicately per- 

 fumed. S. W. China. This and No. 120 are distin- 

 guished from No. 119 by the much smaller corolla-limb 

 and more globular heads. 



122. Giraldiina, Pax (P. muscarioides, Hemsl.). 

 Not farinose, 8-12 in.: Ivs. flaccid, very thin-mem- 

 branaceous, glabrescent, the younger ones cobwebby- 

 pilose below, especially on the nerves, narrowly oblong, 

 acute or obtuse, lobulate-crenate^dentate, long-nar- 

 rowed to a winged petiole which is shorter than the 

 blade: scape 8-12 in. high, glabrous, bearing a many-fld., 

 globose-cylindrical head: fls. strictly sessile, reflexed, 

 blue; calyx open-campanulate, split below the middle, 

 with ovate, acute, denticulate, ciliolate lobes; corolla- 

 tube slender, the limb rather concave, about }&& 

 across, with broad-ovate, entire, very obtuse not emar- 

 ginate lobes: caps, globose, little exceeding the calyx. 

 Shensi, in Cent. China. Intro. 1908. B.M. 8168.

 shaded place.

 stout: Ivs. rosulate, rather thin, 5-11 in. long, narrowly 

 oblanceolate, obtuse or subacute at apex, tapering to 

 long winged petiole, minutely white-hairy, irregularly

 scape often 2 ft. high, much exceeding the Ivs., bearing 

 nearly globose heads about 1 in. diam. of crowded 

 sessile deflexed dark blue or rose-purple fls. with a 

 delicate blue center and which often turn whitish after 

 expansion: calyx about J4in. long, yellow-farinose, 

 unequally lobed; corolla about y$n.. long, glabrous, 

 funnel-shaped, the lobes cuneate-oblong and broadly 

 emarginate: caps, depressed-globose in form. W. 

 China, 10,000-13,000 ft. altitude. Intro. 1906. R.H.S. 

 39:153. 



124. bellidifolia, King. Puberulous: lys. thin-flaccid, 

 not farinose, oblanceolate or spatulate, irregularly sub- 

 lobately dentate, obtuse, narrowed to a petiole more or 

 less equaling the blade: scape 4-8 in. high, glabrous, 

 exceeding the Ivs., bearing a dense many-fld. head: 

 bracts small: fls. reflexed, purplish blue; calyx open- 

 campanulate, puberulent, split below the middle, with 

 ovate obtuse farinose lobes; corolla-tube slender, the 

 throat constricted, annulate, the limb about J^in. 

 across, concave, with obcordate lobes: caps, globose. 

 Sikkim. 



125. Watsonii, Dunn. Lvs. sessile and rosulate, 

 3-6 in. long, oblanceolate, obtuse, long-attenuate at 

 base, more or less lobulate-crenate, hirsute on veins 

 and not farinose: scape strict, very much exceeding the 

 Ivs. i to 1 ft. high), glabrous, farinose at apex, bearing a 

 small globose or ovate spike or head of many sessile 

 deep purple fls. which are J^-^in. long: calyx broad- 

 campanulate, the 5 broad-ovate ciliate teeth equaling 

 the tube; corolla glabrous, dark purple, the tube cylin- 

 drical, the limb cup-shaped, the lobes truncate or 

 obtuse: caps, ovoid. W. Szechuan, China. Scapes 

 powdery yellow. Intro. 1911. R.H.S. 39:157. 



cc. Corotta-lobes more than half as long as the exserted 

 part of the tube. 



126. Littoniana, Forr. Plant 2 ft. or more, with 

 spikes resembling those of kniphofia: Ivs. broadly 

 lanceolate, attenuate into petiole, rounded at apex, 

 irregularly dentate, hairy, about 8 in. long: scape 

 thick, erect, much exceeding the Ivs., farinose toward 

 the top, bearing a dense many-fld. elongated spike 

 (which is 3-5 in. long) of violet-blue, sessile or short- 

 pedicelled fragrant fls.: bracts linear, farinose: calyx 

 broadly campanulate, deeply cut or split, the scarlet 

 lobes ovate or ovate-lanceolate and acute; corolla- 

 tube exceeding calyx, the limb concave and about Vin. 

 diam., the lobes narrow-ovate and entire with rounded 

 apex: caps, small, globose, not exceeding the calyx.

 52:528. R.H.S. 39:156. "Named to commemorate 

 the late Consul Litton of Tengyveh." P. Viali, Franch., 

 is very like this species but smaller and lacking the 

 hairs; the plant described under this name in Pax's 

 monograph is said to be a chimera or confusion of P. 

 deflexa, P. gracilenta, and P. Watsonii. P. cernua (No. 

 110) is by recent authors associated with this group. 



127. gracilenta, Dunn. Perennial, not farinose: Ivs. 

 petioled, in rosettes, oblong and obtuse, narrowed 

 at base, irregularly dentate and wavy, hairy: scape 

 slender, 6-8 in., bearing a head of sessile deflexed deep 

 lilac fls., subtended by lanceolate bracts; calyx broad- 

 campanula te, the teeth ovate and more or less ciliate; 

 corolla with cylindrical tube, the lobes oblong and ter- 

 minated by short tail, giving a fringed effect to the 

 corolla. Yunnan. Intro. 1915. G.C. III. 57:207. 

 A humus-loving species.

128. algida, Adam. Farinose or not so: Ivs. glabrous,

 to a short, frequently obscure, winged petiole, minutely

 head or rarely a congested umbel: bracts lanceolate, 

 acuminate, their base subsaccate: fls. violet; calyx 

 split to the middle, the teeth lanceolate, rather obtuse 

 or rather acute, black, rarely green; corolla-limb about 

 ^m. across, with obcordate trifid lobes: caps, oblong,
