This hybrid resembles in its habit and in the axillary inflorescences M. 

 pinnata Fedde, but the leaflets are thinner and slightly lustrous and the 

 petioles are slenderer, often attaining 3 cm. in length, while on other parts 

 of the same plant they may be scarcely 5 mm. long; the usually 9 or 11 

 leaflets are mostly ovate-lanceolate and sinuately dentate with 4 or 5 spiny 

 teeth on each side. Mahonia Wagneri is about as hardy as M. Aquifolium, 

 but grows much taller, reaching a height of 2.5. mm. When and where it 

 originated is not known; it has been in cultivation In the Nursery of Simon- 

 Louis Freres at Plantieres near Metz since I8G3. In gardens it is some- 

 times found under the name of AI. fascicularis. 



CALYC.VNTIIACEAE 



Calycanthus fertilis var. ferax, comb. nov. — Cferax Michaux, Fl. Bor.- 

 Am. I. 305 (1803). — C laevigahis Willdcnow, Enum. Pi. Hort. Berol. 559 

 (1809). — C pennsylvanicuH Loddiges ex Loudon, Arb. Brit. ii. 937 (1838), 

 pro synon. — Butncria nana Small, Fl. S. E. U. S. 528 (1903), pro parte. 

 Butneria fertilis h. ferax Schneider, 111. Handb. i. 344 (1905). — Calycan- 

 thus fertilis var. laevigatus Bean, Trees & Shrubs, i. 283 (1914). 



This variety differs chiefly in the green under side of the leaves which is 

 glaucous in typical C. fertilis. The closely related C fertilis var. nanus 

 Schelle ((7. nanus Lois.) is likewise green on the under side of the leaves, 

 but smaller in every part. 



LAURACEAE 



Umbellularia califomica Nutt. f. pendula, nom. nov. — U. californica 



" pendulous form " Jepson, Silv. Cal. 243, t. 76 (1900). 



Near Olema, Marin Co. and northward, according to Jepson. 



A tree with wide-spreading branches forming a crown broader than high 

 and with slender pendulous branchlets. A very ornamental form to be 

 recommended for cultivation. 



Litsea sericea Hooker f., Fl. Brit. Ind. v. 156 (1886), — Gamble in Sar- 

 gent, n. Wilson. II. 75 (1914). — Tetranthera sericea WalHch, Cat. No.

 ranthera sikkimensis Meissner in De Candolle, Prodr. xv. pt. i. 181 (1864). 

 Lindera urnhellata Hemsley in Jour. Linn. Soc xxvi. 393 (1891), pro 

 parte, non Thunberg. — Gamble in Sargent, PI. Wilson, ii. 81 (1914). — 

 Lindera mevihranacea Hemsley, 1. c. 389 (1891), pro parte, non Maxi- 

 mowicz. — Gamble, 1. c. (1914). 



The Chinese specimens referred to Lindera urnhellata and L. membra- 

 nacea by Hemsley and Gamble, as far as I have seen them, belong to Litsea 

 except a specimen from Ningpo which may be true Benzoin umheUatuiUy 

 and except Wilson's No. 1634 from Kiangsi and his No. 3675 from Szechuan
