type and agree perfectly well with the herbarium specimens as to the leaves. 

 They are 3 — 4 years old but have not yet flowered. 



Area of distribution: Endemic in Santa Clara and Morro Vinillo. 



137. D. pinnata (Bert, et Dene) Hook, et Am. — JoHOW, Estud. 71. 



Masatierra: On the higher ridges, at the limit of the forest, among shrubs 

 and small trees, not uncommon. — Between Q. Laura and Q. de la Piedra 

 Agujereada, c. 600 m, large trees; El Pangal, west branch, c. 400 m, and on 

 the narrow crest above Pangal, c. 800 m; north face of Co Damajuana, 500 — 

 530 m; V. Colonial, C. Central (Johow), solitary in the forest down to 350 m; 

 Portezuelo de Villagra (JOHOW), scattered on both sides, 5—600 m, one 

 specimen (no. 1235) growing on Blechnum cycadifolium; C. Salsipuedes (Johow), 

 600—750 m, scattered in the shrubberies (beg. fl. 8 /i2 16, no. 79 — one single tree, 

 all others sterile); Q. de los Helechos, on Dicksonia; between Q. Salsipuedes 

 and Pto Ingles; Pto Ingles, central ridge c. 470 m. 



var. insignis Bert. ms„ Johow. — Syn. Rea Berteriana Dene. — Masa- 

 tierra: Q. de la Piedra Agujereada, in wet forest c. 600 m; in the gap between 

 Damajuana and Yunque, c. 580 m, in the humid forest, no. 164 (BERTERO no. 

 1505! [type] labelled »E1 Yunque Majo 1830s; the Kew sheet consists of two 

 leaves and one [complete??] inflorescence, the latter very small). 



Regarding D. Berteriana (insignis), the material collected hitherto is very 

 scarce. BERTERO alone has found the flowers, and very late in the season 

 (May). The very few plants seen by us suggested a pinnata-texm. of extreme 

 shade and moisture. A seedling, quite like that of typical pinnata, was found 

 with them. The primary leaves are simple but denticulate and reniform. 



Area of distribution: Endemic in Masatierra.
