120 WILSON EXPEDITION TO CHINA 



Abelia Engleriana Rehder, n. comb. 

 Linnaea Engleriana Graebner in Bot. Jahrb. XXIX. 132 (1900). 



Western Hupeh: Fang Hsien and Hsing-shan Hsien, thickets, 

 alt. 1200-1600 m., June and September 1907 (No. 289); Icbang, A. 

 Henry (No. 1737). Szech'uan: Taning Hsien, cliffs, alt. 600-900 m., 

 July 1910 (No. 4491); no locality, A. Henry (Nos. 5563, type!, 5573); 

 Chan-chia-shan, Nanch'uan, A. v. Rosthorn (No. 34). 



Rosthorn's No. 34 differs from the type specimen and from Wilson's specimens, 

 which have quite glabrous branchlets in its puberulous and sparingly pilose branch- 

 lets; and the inflorescence does not seem typical. Henry's No. 1737 resembles 

 in foliage somewhat A. macrotera (Graebn.) Rehder, but the flowers are those of 

 A. Engleriana, though borne at the end of short elongated branchlets. 



Abelia myrtilloides, Rehder, n. sp. 



Frutex metralis ramulis gracilibus, junioribus puberulis rubrobrun- 

 neis, annotinis fuscis peridermate decorticante. Folia ovata v. ovato- 

 oblonga v. ovato-lanceolata, acuta v. obtusiuscula et plerumque 

 mucronulata, basi late cuneata, margine revoluta et integra, 1-1.5 

 cm. longa et 4-7 mm. lata, supra obscure viridia, glabra pilis paucis 

 setosis ad marginem versus exceptis, subtus pallida v. cinereo-viridia, 

 venis inconspicuis, glabra pilis villosis ad partem inferiorem costae 

 mediae exceptis; petioli glabri, 1 mm. longi. Flores axillares in apice 

 ramulorum elongatorum, graciliter pedunculati pedunculis puberulis 

 3 mm. longis medio bracteis minutis linearibus institutis; ovarium 

 teres, adpresse pilosum, circa 5 mm. longum; sepala 2, elliptica, 

 ciliata, 7-9 mm. longa et 4-5 mm. lata; corolla campanulato-infun- 

 dibuliformis, infra medium anguste tubulosa supra sensim ampliata, 

 intus hirsuta, extus glabra, circa 3 cm. longa, roseo-purpurea, lobis 

 late ovatis 4 mm. longis; stamina glabra, longiora medium limbum 

 attingentia; stylus glaber, staminibus paullo brevior. Fructus maturi 

 desiderantur. 



Western Szech'uan: cliffs, alt. 600-700 m., June 1903, (Veitch 

 Exped. No. 3722, type); valley of Min River near Sungpan, dry 

 places, alt. 2100-2400 m., August 1910 (No. 4495). 



Abelia myrtilloides is closely related to A. parvifolia Hemsley, which is easily 

 distinguished by its densely pubescent and glandular leaves generally broader and 

 rounded at the base, the short-peduncled flowers and by its longer and narrower 

 sepals. It is also allied to A. Schumannii Rehder, which differs in its broader and 

 larger usually sparingly serrate and thinner leaves pilose on the upper surface, 

 and in its smaller flowers with the tube much shorter and borne on very short 

 peduncles.
