Belotia.* The species should now be known as H. mezicanus. 
Its synonymy and geographical distribution are as follows :— 
H. mexicanus (T'urez.) Sprague in Kew Bull. 1921, 272.—Adeno- 
discus mexicanus Turez. in Bull. Soc. Nat. Mose. 1846, ii. 504.

enéve, Xvili.xix. 122 (1914). H. americanus Hemsl. Biol.

Mexico: Vera Cruz; woods on the Cordillera, 900 m.,

In describing H. glanduliferus, Robinson cited, in addition to 
the type-material from Guatemala, specimens collected by 
EK. W. Nelson in Chiapas, and others collected by A. Tonduz in 
Costa Rica at 8. Francisco de Guadalupe, by the Rio Torres. I 
have not seen this syntype} material, but there are specimens 
in the Kew Herbarium from the same locality, named H. glandu- 
liferus. These differ from type glanduliferus in the relatively 
narrower, more lanceolate leaves, in the cymes, which are opposite 
the foliage-leaves instead of being aggregated into a leafless 
terminal inflorescence, and in the flower-buds, which are more 
swollen above and are terminated by strongly diverging curved 
horns. The characters mentioned seem to warrant the treat- 
ment of the Costa Rica plant as an independent species. 
H. costaricensis Sprague, sp. no affinis H. glandulifero 
Robins., forma foliorum et ea re necnon inflorescentia 
differt. 
Folia ovato-lanceolata vel lanceolata, longe acute acuminata, 
basi rotundata vel inconspicue anguste cordatula, 9-12 cm. 
longa, 3-6 cm. lata, supra asperule stellato-pilosa, pilis praecipue 
biradiatis vel triradiatis nonnullis simplicibus hic inde sparsis, 
radiis curvato-ascendentibus, subtus densius stellato-pilosa radiis 
pluribus; petioli 2-5-4-5 cm. longi. Cymae plerumque oppositi- 
foliae, nec inflorescentiam terminalem aphyllam efformantes. 
Alabastra in sicco circiter 5 mm. longa cornubus inclusis, inferne 
circiter 1-2 mm. diametro, deinde valde inflata, juxta medium 
ultra 2mm. diametro; cornua valde divergentia, curvata, circiter 
0°7 mm. longa. Sepala oblongo-linearia, 6°5—-7°5 mm. longa, 
1 mm. lata, cornua 0°75-1 mm. longa. Petala anguste oblanceo- 
lata, 4-4°5 mm. longa, 1 mm. lata velultra. Stamina circiter 40.

Heliocarpus reticulatus Rose and H. microcar pus Rose, which 
are united by Mr. Watson, differ notably in the fruit. In the 
former the sides of the fruit are clothed with conspicuous plumose
