subter reticulatis ; calyce fructifero quinquepartito, segmentis inflexis 
obovatis vel oblongis parallele nerviis praeter basim fusco-puberulentem 
glabris ; fructibus globosis depressis glabris nitidis 2.5 cm. diametro ; 
pedunculis solitariis 5 mm. longis fusco-pubescentibus ; seminibus ob-

San Luis Porost: San Dieguito, 7-10 June, 1905, Dr. Edward Palmer, 
no. 631 (type, in hb. Gray). Dr. Palmer notes this as a large shrub 
or small tree 2-4 m. high with considerable top and a profusion of dark 
green leaves, the fruit thinly scattered, having the appearance of per- 
simmons, light green but with a patch of red and brown at the exposed 
or lower end. Without the flowers its affinities are doubtful. Com- 
pared with the species listed by Hemsley (Biol. Cent.-Am. Bot. ii. 
300) it differs as follows: from D. ciliata A. DC. in having obovate 
instead of ovate leaves; from D. cuneifolia Hiern, in being glabrous 
instead of hispid or pubescent, as he as in having leaves larger, and 
fruit three times the size; from D. Ebenaster Retz. it differs in the 
shape and size of leaves, much smaller fruit, and quite entire calyx- 
lobes ; from D. velutina Hiern, it differs in the shape of leaves and ab- 
sence of fulvous velutinous pubescence, and from D. tevana Scheele it 
also differs in leaves and pubescence. 
Forestiera puberula, n. sp., divaricate ramosa; ramulis griseis 
et atro-puberulis, verrucosis cum squamulis marcescentibus alabastro- 
rum; foliis fasciculatis lineari-spatulatis apice obtusis basi breve petio- 
latis 5-10 mm. longis 1-nervatis, margine revolutis, superne ‘puberulis, 
subter glabris porulosis ; pedunculis cum foliis fasciculatis, 3-5 mm. lon- 
gis; fructibus (immaturis) cylindraceis falcatis obtusis 8 mm. longis, 
3 mm. diametro.— ZacaTEoas: in arroyas, Cedros, June, 1908, J. #. 
Kirkwood, no. 12 (type, in hb. Gray). 
Related to F. angustifolia Torr., differing chiefly in the puberulent 
stems and leaves, the latter aiallor and strongly revolute. The cylin- 
drical falcate fruit also distinguishes it. 'The flowers are unknown.
