Kiangsi: Ruling, thickets, alt. 1300 m., July 31, 1907 (No. 1552, 

 type); same locality, alt. 1000-1300 m., July 1907 (Nos. 1551, I553)- 

 Western Hupeh: without locality, A. Henry (No. 6462). 



This is a vigorous growing plant distinguished from the type chiefly by its 

 glabrous achenes and larger leaflets. It is more closely allied to the variety sub- 

 sericca Rehder & Wilson which has much smaller, pinnate leaves pubescent below, 

 the inflorescence less than half the length of the leaves and without leafy bracts. 

 Henry's specimen differs in having coarsely toothed leaves sparsely pubescent 

 below and in these characters closely resembles the typical C. brevicaudaia but in 

 its glabrous achenes and other respects it agrees closely with this variety. 



Clematis brevicaudata, var. subsericea Rehder & Wilson, n. var. 



Frutex scandens, 2-4-metralis, ramulis hornotinis initio puberulis. 

 Folia pinnata, in sicco nigrescentia; foliola ovata v. ovato-elliptica, 

 inferiora 3-loba v. 3-partita, acuminata, basi rotundata v. subcordata, 

 Integra v. utrinque dentibus parvis 1-3 mucronulatis, 3-4.5 cm. longa 

 et 1.5-2.5 cm. lata, 3-loba ad 4 cm. lata, supra glabrescentia, subtus 

 breviter sericeo-pilosa; petioluli 5-10 mm. longi; petioli 2-2.5 cm. longi. 

 Inflorescentia axillaris, corymbosa, folio brevior, pluriflora, pluries tri- 

 chotoma; pedicelli 1.5-2 cm. longi, fere glabri; flores 2-2.5 cm. diam., 

 albi, fragrantes; stamina glabra, exteriora stylos superantia, interiora 

 aequantia, filamentis complanatis, antheris ovoideis. Achaenia glabra. 



Western Szech'uan: Yachou Fu, roadsides, alt. 300-600 m., 

 September 1908 (No. 2479). 



The larger, more fleshy, entire or sparsely toothed leaflets densely pubescent 

 below, larger more numerous flowers, larger anthers and glabrous achenes suffi- 

 ciently distinguish this variety from the type. 



Clematis brevicaudata, var. filipes Rehder & Wilson, n. var. 



Ramuli glabri, leviter sulcati. Folia tenuia, in sicco brunnescentia, pinnatim 

 5-7-foliolata; foliola ovata v. late ovato-lanceolata, acuminata, basi rotundata v. 

 truncata, Integra, sed segmenta inferiora interdum profunde 3-lobata, 4-6 cm. 

 longa et 2-3 cm. lata, supra ad venas sparse pubescentia, subtus glabra; petioluli 

 graciles, 1-2.5 cm. longi; petioli 4.5-7 cm. longi, glabra. Inflorescentia axillaris, 

 longe pedunculata, cymosa, 7-9-flora, folio brevior; pedicelli tenues, 2-3.5 cm. 

 longi, infra medium bracteis 2 minutis subulatis instituti; alabastra obovoidea, 

 obtusa; sepala anguste oblonga, 6-8 cm. longa; stamina stylis longiora, filamentis 

 filiformibus, antheris ovoideis vix 1 mm. longis. Achaenia villosa.
