(Exsice. n. 13417.) 
Though this very natural genus is always described as exstipellate, 
yet, in the present species, in the common A. precatorius, L., and in 
the North Brazilian A. tenuiflorus, Spruce,—the only ones at my dis- 
posal,—I find at the base of each short petiolule, and closely appressed 
to the raised margin of the grooved petiole, two minute, free, setaceous 
processes, which it appears to me are certainly true stipelle. 
959 5. Casearia (Iroucana) membranacea, n. sp.; undique glaberrima, 
ramulis subangulatis, foliis oblongo-lanceolatis acutis v. obtusis in pe- 
tiolum brevem euneato-attenuatis margine repandulis v. obsolete pauci- 
crenatis membranaceis creberrime pellucido-punctatis et lineolatis vix 
lucidulis valde subtiliter elevato-reticulatis 23—4 poll. longis 14-2 poll. 
latis petiolo trilineali, floribus e tuberculis axillaribus solitariis paucisve 
pedicello petiolo equilongo suffultis 5-partitis margine ciliatis, stami- 
nibus 8, staminodiis villosissimis, ovario glabro 3-placentato, stigmate 
crasso medio perforato, fructibus flavis ovoideis 8 linealibus, seminibus 
semiovoideis marmoratis,—In fruticetis prope Kiéng-chau, metro- 
polin ins. Hae-nan, d. 18 Nov. 1866, coll. T. Sampson. (Exsice. 
n. 13669.) 
This seems different in the texture of the leaves and other characters 
from any Indian or Ceylon species, and, so far as I can judge from 
descriptions, from the Archipelagic ones enumerated by Miquel. I 
have seen no Asiatic Casearia with such thin leaves. 
Y} 6. Pimpinella (Petrosciadium) Sinica, n. sp.; radice e fibris crassis 
conflata, caule circ. 4-pedali erecto striato pilis crispulis articulatis bre- 
viter tomentoso superne ramoso foliis papyraceis pubentibus radicalibus 
caulinisque inferioribus longe petiolatis exacte cordatis grosse dentatis 
petiolis basi amplexanti-vaginatis superioribus nunc cordatis petiolis 
sensim brevioribus sepius vero trifoliolatis foliolo terminali longius 
petiolulato trisectisve segmentis ovatis basi cuneatis v. truncatis, um- 
bellis 7—12-radiatis, involucri phyllis circ. 5-linearibus nune apicem 
versus 1—2 dentibus auctis radiis ipsis 4-5-plo brevioribus, involucelli 
phyllis similibus radiis dimidio trienteve brevioribus, petalis albidis 
obovato-subrotundis apice emarginatis lacinula inflexa extus pilis raris 
artieulatis obsessis, fructibus brevissime glanduloso-pilosis, stylopodio 
crasso, stylis divergentibus demum reflexis.—Inter gramina, solo are- 
noso, ad angiportum Tsing-yune, fl. North River, prov. Cantoniensis.
