*49. Ch. Crusoeanum nov. spec. -- Fig. 6 b, 7 f — k. Plate 11. 



Frutescens, ad 50 cm vel paulo ultra altum, lignosum. Truncus in fissuris 

 rupium absconditus baud accessus, paulo supra basin ramosus, ramis crassiori- 

 bus ad 9 mm diam.; cortex griseo-viridis vel brunnescens, in ramis junioribus 

 etiam viridis, laevis. Folia versus apicem ramorum subconferta, inferiora mox 

 caduca, longe petiolata, 40 — 80 mm longa ct 20—45 mm lata, petiolo 15—30 mm 

 longo, ovato-triangularia, basi subtruncata vel late rhomboidea, apice rotundata — 

 rotundato-acuminata, sat obtusa, subintegra vel praecipue basin versus irregula- 

 riter dentata usque serrata denticulis brevibus acutis, supra viridia, subtus 

 glaucescentia pilis vesiculosis dense vestita; textura tenuis; nervi flavescentes 

 subtus prominuli. Inflorescentia gynomonoeca paniculata, in ramis terminalis, 

 aphylla, pyramidata, valde laxa ramis patentibus; flores subsolitarii; bracteae 

 minutae. Flores $ 1,5—1,7 mm diam., tepalis late ovatis 1—1,2 mm longis 

 cucullatis basi concretis, vesiculoso-pilosis, valde viridi-callosis, margine hyalino 

 sat irregulari. Stamina primo inclusa dein breviter exserta, filamentis tepalis 

 paulo longioribus vel aequilongis, thecis ovoideis 0,7 — 0,8 mm longis. Ovarium 

 ovoideo-subglobosum vel ovoideo-conicum, 0,6 mm altum, apice subiter contrac- 

 tual stylobasin formans; styli 2 liberi erecto-patentes, e basi incrassata filifor- 

 mes. Flores $ tepalis aliquantum minoribus haud I mm longis (dein auctis), 

 staminodiis 5 minutis. Fructus lenticularis, 1,5 — 1,6 mm diam., stylopodio 

 distincto stylisque erectis, pericarpio opaco punctulato. Semen fere ut in prae- 

 cedente. 



Masatierra: on a rather inaccessible mountain wall in the bottom of the 

 Pangal gorge, in fissures c. 220 m, rare (fl.-fr. 1 /i 17, no. 227). 



Differs from Ch. Sanctae Clarae in the more slender habit, the shape of 

 the leaves and fruit etc., as seen from my description and figures. 



Area of distribution: Endemic in Masatierra.

 sus, paulo supra basin ad 12 cm diam., usque ad apicem ± distinctus, tota 

 longitudine ramis vestitus, inferioribus mortuis; cortex viridis — viridi-stramineus. 

 Folia versus apicem ramorum conferta, inferiora mox caduca, triangularia, basi 

 truncata vel angustata, breviter decurrentia, ± longe et saepe permanifeste acumi- 

 nata, acuta, margine ± profunde, grosse et irregulariter dentato-serrata sed

 dum denticulis 1 — 2 instructis; lamina supra viridi-flavescens, subtus viridi- 

 glauca vesiculoso-pilosa nervis pallidis prominulis; textura sat tenuis; lamina in 

 ramis florigeris (num. 550) circ. 30 — 40 X 20 — 25 mm, petiolo 15 — 50 mm longo, 

 in innovationibus (num. 523) majuscula, ad 80 — 95 mm longa et 45—65 mm lata, 

 petiolo 34 — 45 mm longo. Panicula in ramis terminalis, pyramidata, 4 — 6 cm 

 alta, sat densa, gynomonoeca. Flores £ 1,3 — 1,5 mm diam., tepalis ovato- 

 lanceolatis obtusis valde cucullatis dorso crasse callosis margine late hyalinis ± 

 denticulato-ciliatis. Stamina perigonio paulo longiora breviter exserta. Ovarium 

 ovoideo-conicum 1,5 mm altum in rostrum longum productum; styli 2 basi sub- 

 incrassati valde patentes liberi. Flores <j> tepalis minoribus, staminodiis 5 minutis. 

 Fructus longe rostratus, 2—2,5 mrn longus, 1,5 mm diam., rostro 1—1,4 mm
