found in company with the pig-nut; " but that the pig-nut does not alwa\h 

 accompany the mocker-nut, which is satisfied with a much Jess substantial 

 soil." The wood of this tree is stronger and better than that of any other kind 

 of hickory ; and, on account of its extreme tenacity, it is preferred to any of the 

 other American woods for axletreesand axe-handles. For this reason, Michaux 

 recommends its introduction into the forests of Europe, where its success, he 

 says, would be certain. There are plants in the Hackney Arboretum.

longitudinal lines of white; in which it resembles a nutmeg, which is the seed of Myristica mos- 



chata ; and hence the epithet myristicaDformis. A 



native of South Carolina. (Mic/ix. N. A. S., Pursh

Description, $c. Very little is known of this tree. 

 Michaux described only from a branch and a handful 

 of nuts, which were given to him by a gardener at 

 Charleston. The leaves consist of four or six small 

 leaflets, and an odd one ; and the nuts, which are very 

 small, smooth, and brown, streaked with white, 

 strongly resemble a nutmeg ; whence the name. The 

 shell is so thick, that it constitutes two thirds of the 

 nut, which is, in consequence, very hard, and has a 

 minute kernel, which is inferior even to that of the 

 pig-nut. Michaux had no means of ascertaining the 

 value of the wood ; but he found the shoots of the 

 current year extremely tough and flexible. (Syl., i. p. 

 199.) This sort is not yet introduced. 



9. C. MICROCA'RPA A T H//. The small-fruited Carya, or Hickory. 



Identification. Nutt. Gen. N. Amer. PL, 2. p. 221. 



Spec. Char., ^c. Leaflets, in a leaf, about 5; oblong-lanceolate, conspicuously acuminate, argutely 

 serrulate, glabrous ; glandular beneath ; terminal one subpetiolate. Fruit subglobose. Husk thin. 

 Nut partly quadrangular, small ; its shell rather thin, its mucro obsolete and truncate. Indigenous 

 to the banks of the Schuylkill, in the vicinity of Philadelphia. (Nuttall.} A large tree, with even 

 bark. Fruit much like that of C. tomentdsa, and eatable ; but very small, the nut not exceeding 

 the size of a nutmeg. Catkins tritid, very long, glabrous, without involucre; scales 3-parted, their 

 lateral segments ovate, the central one linear. Anthers pilose, mostly 4, sometimes 3, sometimes 

 5. Female flowers 2 or 3 together; common peduncle bracteolate. Segments of the calyx 

 very long, and somewhat leafy. Stigma sessile, discoid, 4-lobed, somewhat rhomboidal. (Nuttatl.) 

 Not yet introduced.

A pp. i. Other Kinds of Carya. 



C. ambigua ; Juglans ambiglialfifcfce. 2V. A. %/. , 190. ; is a kind which Michaux found in the 

 gardens of the Petit Trianon, where it had heen raised from American seeds. Its bark exfoliates in 

 strips ; its leaves resemble those of C sulcata ; and its fruit that of C. alba, but is smaller. From this 

 description, it appears to belong to the shell-bark hickories. 



C. puMscens Lk. En.. Sweet's Hort. Brit, ed. 1833, is a kind of which we know nothing. 



C. rigida, J. rfgida Load. Cat., ed. 1836. The plants bearing this name in the Hackney Arboretum 

 appear to be varieties of C. alba.
