in ramos elongatos flaccidos basi diviso inter alia recedit. 
Planta 30-40 cm. alta. Folia ad 4o cm. longa, ad 3.3 cm. lata, 
anguste lanceolata, acuminata, in sicco tenuiter membranacea

debiles divisus; bracteae 1-2.5 cm. longae lineari-lanceolatae, 
longe acuminatae, pedicellis nunc breviores, nunc fere aequantes.

anthii albi segmenta circ. 1.3 cm. longa, anguste lanceolata, sub- 
acuta, margine late scariosa. Antherae 6 mm. longae filamenta

The above and the following two species are akin to C. undu- 
latum, Wall. showing branched racemes with scattered flowers 
or groups of flowers. In C. oreogenes the inflorescences are 
erect and somewhat rigid; in the other two species they are 
weak and flaccid. C. mekongense is distinguished by the very 
large bracts; C. flaccidum by the scape much divided from near 
the base into branches which are almost decumbent and bear 
the flowers at remote nodes. 
Chlorophytum mekongense, WW. W. Sm. Sp. nov. 
Species ex affinitate C. wndulati, Wall. a quo foltis perlatis, 
bracteis praelongis saepe 5-6 cm. superantibus, inter alia recog- 
noscitur. 
Planta robusta. Folia plerumque 8-10, 30-60 em. longa, ad 
5 em. lata, anguste oblanceolata, longe acuminata, in partem 
petiolarem longe attenuata, in sicco tenuiter membranacea. 
Scapus foliis multo brevior ad 1 5 cm. longus sed vix bene evolu- 
tus, crassiusculus, flexilis haud rigidus, mediocriter florosus. 
Bracteae permagnae saepe 5-6 cm. longae, nunc ad 8 cm., lanceo-
