 new plants and forming more or less matted patches, as in A. rhizophorum. 



Asplenium Harrisi (EuaspleniumJ, Jenm., n. sp. — Rootstcck little larger 

 ihan a piu's head, densely clothed with minute dark scales ; stipites tufted, thread- 

 ike, dark glossy brown, 1 to IJ inch long, often fiexuose, channelled ; frondu pin- 

 nate, semi-erect or prostate, 3 to 5 inches long, J to § inch wide ; rachis very 

 slender glossy, brown, channelled, sliglitly margined in the upper part, and extend- 

 ing its thread-like, naked tail 1 to 1| inch, gemmiferous, and rooting at the end, 

 pinnae bright, glossy, translucent, mpmbranous, naked, apart, spreading, both the 

 upper and lower gradually reduced, 2 to 3 lines long, rounded and crenate in the 

 upper and outer part, the base truncate, dimidiate frcm the infniior side being cut 

 away, the minute upper ones cuneate : veins fine, forke 1, flabellate, open, no mid- 

 veins, terminating within the margin : EOri medial oblique, ^ to 1 line in length, 

 occupying both the superior and infeiior veinlets ; involucres silverj, flat, eventu- 

 ally raised. Jamaica, Blue Mountain Peak, over 7,000 feet elevation, ccllected

Asplenium Fawcetti. 



This very interesting species, and beautiful addition to the Trichomanes 

 group of the genus in Jamaica, was gathered last November by Mr. Wm. 

 Harris, Superintendent of the Hill Gardens, and at bis request, is named 

 after his chief, the Director of Public Gardens and Plantations. Its dis- 

 tinguishing features are the numerous pincse (three doz. to five doz. on a 

 side), their dwindling to nearly, but not quite nothing at the apex of the 

 frond, the very fragile rachis and the markedly conspicuous, silver coloured 

 involucres. The rachis which is occasionally wavy, sometimes bears a bud 

 in the axis of a leaflet an inch or so short of the apex. The plant is widely 

 distinct from A. monanthemum, L., as well as the other species of the 

 group. 



*Asj)lenium Fawcetti, Jenm., n. sp.— Root stocks clustered, very small, fibrous 

 the centre densely clothed with fine, attenuated castaneous scales, stipites in tufts, 

 semi-erect, slender, wiry but fragile, margined, castaneous or darker, ^ — 2 inches 

 long, fronds spreading, linear, and much narrowed to the apex, but without a 

 naked tail, a span to 1 foot long, six to eight lines wide, narrowed at the base, 

 thin, dark green, naked, rachis very slender, fragile, dark, glossy, channelled with 

 scarious margins , pinnse very numerous, sessile dwindling mostly to mere pin-dots 

 in the outer part of the fronds, and reduced to auricles at the base, rhomboidal and 

 subdimidiate, the superior base wide, but hardly auricled, the inferior base absent 

 4 to 5 lines long, 2 lines wide, spreading, contiguous, but not touching, broadly 

 rounded, and conspicuously bluntly toothed along th^ upper and round the outer 

 and inferior margins to where the base is cut away ; veins pinnate at an acute angle, 

 falling short in the teeth, three to a side, all simple, but the inferior one on the 

 superior base, which is once forked from below the middle , sori on both sides of 

 the mid-vein, two or three to a side, lateral on the veins, about one line long dis- 

 tant from the margin, and usually short of the base, involucres conspicuous, 

 bright, silvery.

POLYPODIUM HaRRISII. 



This highly interesting species comes in between Polypodium trifurcatum 

 and Enterosora Campbelli, all three havinu; a very close resemblance and 

 evident connection. In all, the sori are move or less sank, but extrude 

 when mature. In this and P. trifurcatum, they are in oval or round pits,
