EASTWOOD. — SOME UNDESCRIBED MEXICAN PHANEROGAMS. 605 



subter reticularis ; calyce fructifero quinquepartito, segmentis inflexis 

 obovatis vel oblongis parallele nerviis praeter basini fusco-puberulentem 

 glabris ; fructibus globosis depressis glabris nitidis 2.5 cm. diametro ; 

 pedunculis solitariis 5 mm. longis fusco-pubescentibus ; seminibus ob- 

 longis 12 mm. longis 7 mm. latis, una facie convexa, altera plana. — 

 San Luis Potosi : 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 well 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. velut/'na Hiern, it differs in the shape of leaves and ab- 

 sence of fulvous velutinous pubescence, and from D. texana 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. — Zacatecas : in arroyas, Cedros, June, 1908, J. E. 

 Kirkwood, no. 12 (type, in hb. Gray). 



Related to F. angustifolia Torr., differing chiefly in the puberulent 

 stems and leaves, the latter smaller and strongly revolute. The cylin- 

 drical falcate fruit also distinguishes it. The flowers are unknown. 



Centaurium pusillum, n. sp., nanum 4-8 cm. altum ramosissimum 

 glabrum ; ramis tenuissimis quadrangulatis ; foliis imis rosulatis, primis 

 spatulatis, ceteris oblanceolatis acutis 1 cm. longis 2 mm. latis, nerviis 

 obscuris ; foliis caulinis lanceolatis acuminatis vel apice acutis basi 

 amplexicaulibus ; floribus longe pedunculatis non-numquam sessilibus 

 tetrameris 7 mm. longis ; pedunculis inter angulos striatis ; calycis la- 

 ciniis fere liberis lanceolatis acutis carinatis, margine membranaceis 3-4 

 mm. longis, tubo brevi multo longioribus ; corollae laciniis oblongis vel 

 ellipticis obtusis 4 mm. longis 2 mm. latis contortis et supra capsulam 

 marcescentibus, tubo calycem aequanti, faucibus constrictis ; filamentis 

 in faucibus insertis capillaribus 2 mm. longis j antheris ovato-cordatis
