602 WILSON EXPEDITION TO CHINA 



1908 (No. 1075; bush 2-3 m. tall, fruit blue-black); same locality, 

 side of streams, alt. 1000-1600 m., June and November 1908 (No. 1290; 

 bush 1.5-2.5 m. tall, flowers white); without precise locality, July 

 1904 (Veitch Exped. No. 4083) ; Nanch'uan, " Chao-chia-ai," Sep- 

 tember 29, 1891, A. von Rosihorn (No. 1052). 



Though in the original description of L. Delavayanum the corolla is described 

 as rotate, I find that in a specimen I collected myself in 1901 from a plant under 

 this name in Vilmorin's Fruticetum at Les Barres the corolla is infundibuliform as 

 in L. Prattii. Another specimen of L. Delavayanum sent to me recently by M. 

 Mottet from Vilmorin's nursery at Verrieres is exactly like it. As both specimens 

 agree in all other characters with the original description, I must assume that the 

 description of the corolla as rotate is not quite correct, especially as the tube is 

 described as " tubo calycem circiter duplo superante." The specimens agree well 

 with those collected by Henry and by Wilson and referred to L. Prattii except 

 that the pedicels are slightly hairy toward the base. Ligustrum Delavayanum 

 seems somewhat variable in the size and shape of the leaves. Wilson's No. 4083 

 has the leaves on vigorous shoots up to 6.5 cm. long and almost oblong-lanceolate 

 in outline, while on the flowering branchlets they are 2-3.5 cm. long and differ 

 little from those of typical L. Delavayanum. The panicles, too, are larger and 

 more pyramidal in outline and measure from 6 to 7 cm. in length; the whole 

 specimen resembles closely L. ovalifolium Hasskarl except that it has the branch- 

 lets and the axes of the inflorescence puberulous and terete and rather longer 

 petioles. In spite of these differences, however, I cannot take No. 4083 for any- 

 thing else than an extremely vigorous specimen of L. Delavayanum. A. von 

 Rosthorn's No. 1052 is somewhat intermediate. 



Ligustrum ionandrian Diels from Yunnan seems very near and is possibly only 

 a form of this species with stunted flowering branchlets and short and dense 

 panicles.
