Boehmeria Jacq. 



44. B. excelsa (Bert, ex Steud.) Wedd. — Johow, Estud. 124. 



Masatierra: The characteristic tree of the river beds, in groups along 

 the streams in the valleys; forms the westernmost forest patch in the island. — 

 Pto Frances (Johow); El Rabanal; El Pangal, common near the entrance 

 (fl. n /i2 16, no. 105 £, 106 J 1 ); Q. Damajuana, c. 200 m, scattered trees (fi. 6 /i2 16, 

 no. 58 £); Plazoleta del Yunque, not uncommon (also Johow); V. Colonial, 

 slopes of C. Central, c. 400 m; Q. Seca, stray specimens, 300 m; Pto Ingles, 

 west branch, fine groups by the stream in the flat part of the valley; Q. Juanango, 

 2I 5 m > Q- Villagra, some small trees, c. 400 m; Q. de la Choza, solitary trees 

 in dense forest, c. 250 m; foot of Co Chumacera, small pure stand. 



Monoecious; generally the branchlets are either J 1 or $ ; male flowers 

 were not observed in female glomerules, but in male ones, which seem to be 

 much rarer, single female flowers occurred. 



Unfortunately, I have not found ripe fruits. Habitually, it is very like 

 B. dealbata Cheesem. from the Kermadec Islands, as well as other Pacific spe- 

 cies, to which B. excelsa probably is nearly related. It has also the appearance 

 of Pipturus albidus Gray from Hawaii, but as far as can be judged from flowers 

 only it is a true Boehmeria. 



Area of distribution: Endemic in Masatierra. 



Parietaria L. 



45. P. debilis Forst. -- Syn. P. humifusa, Rich., Johow, Estud. 124. 



Masatierra: B. del Padre, stony beach, faded ( 15 /i 17, no. 297). 



Masafuera: on the beach between Casas and Mono ( 18 /2 17, no. 1208; 

 Johow collected it near this place); Q. de las Casas, walls of the canyon, scarce 

 (fl. G /s 17, no. 368); Q. Angosta, in the gorge by a small waterfall. 



Area of distribution: Subcosmopolitan. 



Loranthaceae. 

 Phrygilanthus Eichl. 



46. P. Berteroi (Hook, et Arn.) Reiche. — Syn. Loranthus Berteroi Hook, 

 et Arn., JOHOW, Estud. 126. 



Masatierra: Bertero! Bridges! Parasitic, according to the former, on 

 Myrcengenia, the commonest forest tree. 



We greatly regret having been unable to rediscover this interesting plant. 

 It is certainly very rare. I hardly think that any of the islanders, of which many 

 spend a great deal of their time in the woods, had ever seen this, and only 

 very few had heard of its existence, while all of them were very familiar with 

 other species of the same genus, known as »quintral» on the mainland. 



Area of distribution: Endemic in Masatierra.
