cilia te; corolla deeply 5-cleft, lobes spreading from a short tube, erose; 

 stamens 10, unequal, filaments slender, densely villose at base, anthers 

 relatively large, dark purple; pistil shorter than stamens, ovary densely 

 villose, style relatively stout, curved, persistent, pilose at base, stigma 

 capitate. Fruit ovoid, 5-8 mm. long, pubescent, enclosed within the 

 colored, persistent calyx, topped with style; seeds minute, wingless. 



Habitat. Northeastern Asia, alpine regions from the Stanovoi Mountains 

 eastward; Korea, higher mountains of the north. 



This tiny alpine plant is in many ways a diminutive of its close relative, 

 R. kamtschaticum Pall. It appears to be confined to continental north- 

 eastern Asia and finds its southern limit of distribution on Paktu-san and a 

 few other of the high mountains of Korea. It was discovered early in the 

 nineteenth century on the Stanovoi Mountains by a Russian traveller, 

 Redowsky, but was confused with the European R. Chamaecistus Linn, 

 now known as Rhodothamnus Chamaecistus Reichb. I did not see it

INCUNABULA IN THE LIBRARY OF THE 



ARNOLD ARBORETUM 



Ethelyn M. Tucker 



To the bibliophile perhaps no class of books is so interesting as the 

 incunabula, important not only from the point of view of the history of 

 printing but also for their artistic and scientific value. The typo- 

 graphical interest of the 15th century books predominated for so many 

 years that their scientific interest was for a time almost lost sight of, and 

 fortunate is the scientific library which now possesses a few of these 

 treasures, bearing on its particular subject. 



In 1905 the Arnold Arboretum Library received by gift from Mrs. J. 

 Montgomery Sears its first book printed before the year 1500. It has 

 gradually acquired others, largely by gift from Mrs. Sears, and by her 

 recent gift of three important books the collection has received a notable 

 addition. These recent gifts are her copy of the Herbarium of Apuleius 

 Platonicus or Barbarus, probably the only copy in the United States, 

 and two works of Columella, of which no other copies have been reported 



in this country, namely: 



Jo. Moderati Columelle ortuli commentariu || incipit feliciter. [Romae, 



Steph Plannck.] ff. 10. Hain 5495; and 



Lucii Junii Moderati Columelle de Cultu || hortorum Liber xi. 

 Quern. Pub. Virgilius || M. I. Georgicis Posteris edendum dimissit || Ad 

 eiusde Carmen Prefatio. ff. 10. Hain 5498. 



For the following note on the Herbarium of Apuleius I have drawn 

 from Mrs. Arber's "Herbals," and Dr. Arnold C. Kleb's "Herbals of the
