in the forks, pedunculate, scarcely \ line long, the lobes fimbriate, the 

 glands (3 or 4) broadly stipitate, minute, rounded, entire: capsule 

 smooth, J line long: seed ovate, smooth or very obscurely indented, 

 ecarunculate. — On wet grassy borders of prairie ponds, Flor de Ma- 

 ria, State of Mexico; October, IH'JO (n. ooOo). 2s'ot nearly related 

 to any other of our species of the section. 



Phvllanthus Pkinglei. a small tree (15 feet high), with 

 smooth gray bark on the numerous branches, and the slender herba- 

 ceous branchlets sulcate-angled : leaves distichous, thin, round-ovate to 

 orbicular or round-obovate, acutish or usually obtuse or retuse at the 

 summit, as also at base, 6 to 12 lines long or le^s, on petioles about a 

 line long ; stipules short, obtuse and scarious : pistillate flowers soli- 

 tary (or only 2 or 3) in the axils, on very slender pedicels 2 to 5 lines 

 long ; calyx G-parted, the oblong segments nearly equal ; disk cupu- 

 late; styles bifid, spreading: staminate flowers and fruit unknown. — 

 On limestone ledges at Las Palmas, San Luis Potosi ; June, 1890 

 (d. 3532). The material is insuflricient for a full description, but it 

 seems quite unlike any known species that is likely to be found in 

 Mexico. 



Croton (Eucroton) calvescens. Shrubby, herbaceous above, 

 the young branches and leaves densely covered with a white or gray- 

 ish stellate tomentum, soon glabrate and more or less scabrous with a 

 rigid substellate puberulence : stipules obsolete ; leaves ovate to ovate- 

 lanceolate, acuminate, rounded and biglandular at base, serrulate, 2 or 

 3 inches long on petioles 3 to 12 lines long: racemes terminal, sessile, 

 3 to 9 lines long, dense, pistillate at base ; pedicels a line long: sta- 

 mens 9 to 12; calyx-lobes of pistillate flowers deltoid, obtuse, not be- 

 coming reflexed : ovary densely stellate-pubescent and hispid; styles 

 once divided; capsule becoming nearly glabrous, ellipsoidal: seed 

 smooth and shining, 2| lines long. — Collected by Dr. E. Palmer in 

 1886 (n. 706) near Chapala, Jalisco, and by Mr. Pringle in Novem- 

 ber, 1890, on hillsides near Patzcuaro in Michoacan (n. 3346). Near 

 forms of C. flavus. 



Croton (Eutropia) el^agnoides. A shrub or small tree, 10 

 to 15 feet high: leaves 3-5-nerved at base, eglandular, ovate to lan- 

 ceolate, acutish to acuminate, green above and roughish with a slight 

 scurfy puberulence, white beneath with a dense compact lepidote coat- 

 ing (as also the inflorescence and fruit), | to 2 inches long, short-petio- 

 late : racemes becoming 4 to G inches long, pistillate below ; staminate 

 flowers nearly 3 lines broad, with narrowl}^ lanceolate acutish pubes- 

 cent petals a;id about 15 stamens ; pistillate flowers scattered, the
