Ternifolia Group of Macadamia — STOREY 
inches in length and 1-3 inches in width. They 
occur in whorls of three or four, with three by 
far the most common. Young seedlings and 
new shoots may have them in opposite pairs. 
The inflorescences are borne on mature branch- 
lets, usually on the growth increments produced 
in the top two or three, or more, seasons pre- 
ceding the most recently matured ones. The 
flowers are white. The racemes upon which 
they are borne vary among individuals, from 
as short as 4 inches to as long as 12 inches or 
more. The number of flowers on the racemes 
ranges from 100 to 300 (Fig. 1). The bulk of 
the crop matures from March to June in Aus- 
tralia, July to November in Hawaii, and No- 
vember to March in California. However, some 
fruit is produced almost every month in the 
year, consequently the species is sometimes 
called "everbearing.” 
Although this species was not recognized as 
new and given a specific epithet until 1897 
(Maiden and Betche, 1897:624), it was intro- 
duced into California as a potential economic 
plant, under the invalid name M. ternata , in 
1879 by the University of California College 
of Agriculture (1881:66) and planted on the 
campus at Berkeley in 1882 (Butterfield 1963: 
48). Two trees of this introduction continue 
to grow on the Berkeley campus. Almost simul- 
taneously, at a time reported to be between 
1881 and 1885 (Pope 1929:2; Thevenin 1961: 
15), W. H. Purvis of Honokaa, Hawaii, intro- 
duced the species, as M. ternifolia, which he 
planted at Kapulena. A second introduction 
into Hawaii was made in 1892 by E. W. and 
R. A. Jordan who planted the trees at the 
former’s home on Wyllie Street in Honolulu 
(Pope 1929:2). This introduction became the 
source of the principal commercial varieties 
cultivated in Hawaii today.
