regulariter serrata dentibus utrinque 6-9, superiora multo minora, paucidentata- 

 subintegra, basi longe cuneata, suprema bracteiformia. Inflorescentia densa 

 vel laxa, foliosa, e dichasiis bracteolatis plerumque 3-floris composita. Flores 

 brevissime (1 mm) pedicellati, omnino laeves. Ovarium subtetragonum et sat 

 distincte 8-lineatum, 0,9—1 mm longum et fere latum, cum pedicello ± rufescens. 

 Sepala 4 late ovato-triangularia, suberecta, 0,9 mm longa. Petala 4 navicularia 

 alborosea carinata, 3 — 3,5 mm longa, manifeste unguiculata. Stamina 8 fila- 

 mentis c. 1 mm longis, antheris flavo-roseis 2 — 2,3 mm. Styli 4, 0,8 mm longi, 

 stigmata rosea papillis pauci-(i — 3)cellularibus. Fructus anguste tetragono- 

 ovoideus, in specim. num. 304 cum sepalis 4 — 4,5 mm longus et 1,7 — 1,9 mm 

 latus, non alatus sed lineis paulo elevatis 8 notatus, fusco-viridis. 



Masatierra: Not rare on the dry, rocky ridges, also on open, stony 

 ground in the forest belt. Rabanal (Johow); El Pangal, on the western slope; 

 C. Centinela (Johow); V. Colonial, C. Central (also Johow), 570 m (fl.-fr. 18 /i 17, 

 no. 304), Q. del Monte Maderugo, road-side in the macal, 240 m, and rocky 

 wall, 390 m; C. Salsipuedes, frequent, 350 — 650 m (fl. 20 /i2 16, no. 172); Porte- 

 zuelo de Villagra, not rare on both sides (fl. V12 16, no. 34 — also observed 

 by Johow); ridge between Vaqueria and Q. Juanango, 300 m; O. Juanango, 

 outer part. South side of the island, Q. Villagra, rare in the forest c. 500 m; 

 east side of B. Chupones, barren slopes. 



This differs widely from the typical scabrous H. erecta, but it is more like 

 what I have called H. Colensoi, especially the more stunted form of H. masa- 

 tierrana, growing on the sunny ridges (no. 34, 172). Of this I got no fruits. 

 JOHOW collected fruiting specimens of exactly the same habitus (no. 6). The 

 fruits of these, only 3,5 — 4 mm long (but hardly quite ripe) come very near 

 H. Colensoi, where, however, they are transversely rugose. Both have traces 

 of wings (see fig. 19 h and 17 h). Still, I believe there is only one species in 

 Masatierra and that H. Colensoi is different. 



Area of distribution: Endemic in Masatierra.

Suffrutex semimetralis patente opposite ramosus glaber laevissimus. Rami 

 cylindracei — obscure tetragoni 4-lineati. Folia subcarnosula laete viridia, inferiora 

 petiolo 8 — 10 mm longo suffulta, lamina ovato-lanceolata, basi late cuneata, 

 margine incrassata, grosse serrata dentibus utrinque 9 — 11, c. 45 mm longa et 

 20 mm lata, superiora sensim minora et brevius petiolata, suprema subrhomboidea 

 subintegra. Inflorescentia laxa foliosa, e dichasiis bracteolatis 1 — 3 (rarius ad 5)- 

 floris composita. Flores brevissime (V2 — I mm) pedicellati, omnino laeves. 

 Ovarium ovoideum 1,5 mm longum et 1,2 latum. Sepala 4 triangulata margine 

 integro, 1 — 1,2 mm longa. Petala 4 viridia fusconotata, navicularia, carinata, 

 manifeste unguiculata, 2,5 — 3 mm longa. Stamina 8 filamentis ad 1,5 mm longis, 

 antheris ad 1,6 mm. Styli sepalis aequilongi, stigmata alba, papillis longis sed 

 paucicellularibus. Fructus pyriformis quam in ceteris major, cum sepalis 4,2 — 4,6 

 mm longus, basi 3—3,2 mm latus, fere semper alis omnino destitutus, maturus 

 ± violascens, in sicco obscure 4-sulcatus. Adsunt specimina fructibus tubercu- 

 latis nee non alia fructibus irreoulariter alulatis.
