ROBINSON AND BARTLETT. — PLANTS FROM GUATEMALA AND MEXICO. 55 
place.” Euphorbia ephedromorpha, a unique plant in both habital and 
technical characters, belongs to the § Alectoroctonum. The only Eu- 
phorbia of the same affinity which has been seen is in the Gray Her- 
barium from Cerro Quiengola, Oaxaca, Mexico, Caec. et Ed. Seler, no. 
1611. It represents a clearly distinct new species of very similar habit, 
but it cannot be described on account of the scantiness of the material. 
Acalypha euphrasiostachys Bartlett, n. sp., fruticosa ramosa 
1 m. altitudine; ramulis junioribus molliter pubescentibus ochraceis 
aetate glabriuscalis rubentibus ; foliorum limbis ovatis 3-8 cin. longis 
2-4.5 cm. latis- dentatis utrinque molliter pubescentibus vel supra 
solum secus nervos pilosis, apice acutis vel caudato-acutis, basi max- 
ime variabilibus acutis rotundatis vel subcordatis ; petiolis limbo ca. 
quintuplo brevioribus ; spicis masculis axillaribus ‘sessilibus ca. 1 em. 
longis nunquam ad basin bracteis femineis praeditis; spicis femineis 
axillaribus 2.5-7 em. longis 4-7- bracteatis, dispositione formaque 
tearum speciebus alpinis generis Huphrasiae persimilibus ; bracteis 
femineis 8 mm. longis 10 mm. latis unifloris 13-dentatis, dentibus 
modice longis alternis brevioribus ; calycis masculi segmentis 4 ovatis 
0.5 mm. longis, feminei segmentis 3 ovatis ca. 1 mm. longis; ovario 
dense piloso; stylis viridibus bracteo exsertis 7 mm. longis multila- 
cinuligeris. — Zacapa, Department of Zacapa, Guatemala, 24 January, 
1905, @. C. Deam, no. 190 (type, in hb. Gray). A species near Watson’s 
Acalypha multispicata, which has very similar fertile spikes. 
Clusia quadrangula Bartlett, n. sp-, arborea 5-6 m. alta ubique 
glabra; ramis modice crassis subteretibus ; foliis coriaceis ovatis 3-4 
em. latis 7-11 em. longis, apice basique acutis, petiolo quam limbo 
quintuplo brevioribus ; nervis lateralibus numerosis parallelis utrinque 
. prominulis inter se 1-2 mm. distantibus angulo ca. 45° a costa abeunti- 
bus; inflorescentia terminali quam foliis superis duplo breviore ramosa, 
ramulis angulosis plerumque in florem unum brevipedicellatum termi- 
nantibus; bracteolis infimis semi-ovatis basi connatis, sequentibus (a 
sepalis non different) sepalisque 14-16 per paria decussatis coriaceis 
semi-ovatis cordatis dorso carinatis, collective obpyramidatis quadran- 
gulis (ex quo nomen specificum) ; petalis 4 coriaceis late ovatis quam 
sepalis duplo longioribus; staminibus pernumerosis in receptaculo 
elevato valde concavo pentagono dense aggregatis ris, omnibus an- 
theriferis, filamentis perbrevibus paene nullis, antheris rimula longitu- 
dinali dehiscentibus, connectivis haud productis. Flores feminei ignoti. 
— Livingston, Department of Izabal, Guatemala, February 17, 1905, C. 
C. Deam, no. 56 (type, in hb. Gray). This Clusia has no obvious relation- 
ship with any heretofore described species. Until pistillate flowers are 
discovered it seems unwise to characterize a new section for its reception.
