The following hybrid Adiantums were raised iu the 

 Singapore Botanic Gardens. They have been named pro- 

 visionally and as they are not yet known outside of these 

 Gardens each one is roughly described: — 



1. "Beauty of Singapore." Stipe black shining 1 

 foot tall. Frond tripinnate 18" x 12" very lax, pinnae dis- 

 tant 1/V2" apart, pinnules 3"-4" long with rather long stalks 

 nearly 1". Leafits light, pale green 1" long oblique, one 

 side quite straight and usually much longer than the other 

 the two basal sides forming an obtuse angle, rest of outline 

 ovate or rounded, triangular, shortly incised on the upper 

 margin with oblong truncate rounded lobes. Lower leaf- 

 its smaller under J terminals ones J" or more both ways. 

 Sori 10-17 on each leaf it usually 2 to each lobe, all round 

 the edge except the straight bases on the extreme edge on 

 the underside. Probably terienim hybrid. 



2. "Tanglin." Stipe black shining 1 foot tall or more, 

 frond lax tripinnate 15" long 8" across, thin, about 10 pin- 

 nae, pinnules about 5" long about 6 leafits fan-shaped 

 oblique narrowed actually to the base, margin above irre- 

 gularly lobed with oblong truncate short lobes usually J," 

 long or less dull bluish-green, sori black 5-15 on and beneath 

 the upper edge often connate very irregular. Probably 

 Bausei-tenerum hybrid. 



3. " Bidadari." Stipe 10" tall ebeneous, frond lax 

 triangular in out line deep blue green tripinnate pinnae 

 arched lax rachis slender, leafits trapeziforme flabellate 

 %" x §" narrowed for the most of its length to the base, 

 terminal one broad fan-shaped, the others irregularly trun- 

 cate lobed. Sori brown 5-13, short, usually linear, several 

 run together. A very elegant dark green fern terminal 

 leafits often very deeply cut into linear and oblong lobes. 

 Probably tenermn-fragrantisswi urn hybrid. 



4. "Mrs. Napier." Stipe ebeneous 1 foot tall, frond 

 large broadly triangular 14" x 16" tripinnate bright light 

 green. Leafits obovate J" or less oblique or regular sides 

 straight apex broad mostly very shortly lobed. Sori 10-12 

 mostly separate occasionally run together. A handsome 

 fern probably a cross between tenerum and Mariesii. 



5. "Shamrock." Stipe ebeneous, frond very lax 

 branches remote and few 12" x 10" shortly trippinuate with 

 few leafits. Leafits deep green bluish eery irregular base 

 absolutely straight slightly angled or refuse, cordate |"
