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 Vaquerfa and Q. Juanango, 300 m; Q. 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 ( 1 /g — 1 mm) pedicellati, omnino laeves. 

 Ovarium ovoideum 1,5 mm longum et i,a 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 irregulariter alulatis.
