Flores monoici; @ in ramo brevi longioreve terminales, innovatione 
simplice suffulti. Bracteze foliis sublongiores, ad ? bifida, compli- 
cate, acute, subserrulate v. grosse serrate, raro fere integerrime, 
lobis obovato-lanceolatis, inferiore breviore angustioreque ; bracteola 
lanceolata ad 4 bifida, segmentis acutis, integerrima. 
Perianthia vix emersa pyriformia subcompressa, marginibus acute 
carinatis, postice ventricosa obscure bicarinulata, apice in 3 v. 4 
umbones cornuaye brevissima erecta obtusa producta, demum 
3—4-fida. Capsula spheerica. 
Andreecia pro more longispica, ramum totum—raro ejus apicem solum— 
tenentia, julacea ; bracteze 4-10-jugze sat magne imbricatee. 
Prope Mandos fluminis Negro, in arboribus humilibus planitiei arenosi 
“Umirisil” dicti, advenit forma pulchella dense ceespitoso-stratificata, 
foliolis late ovalibus apicibus acuminatis. 
The ocellus near the base of each leaf consists normally of 2 (rarely 
more) enlarged cells, covered on their under surface with a grumous 
greenish waxy mass, which is easily removable and finally falls away, 
leaving the cells scariose, pellucid and nearly empty. It therefore pro- 
bably exudes from the cells, but whether it is a fungous growth, ora 
morbid state of the chlorophyl I am unable to say.

Pro L. Cubensis var. habenda; differt autem caule longiori, szepe pollicari, 
in planum fere ramoso; foliis planioribus rotundatis obtusatisve 
raro subacutis, fere constanter mtegerrimis, lobulo 4-plo breviore 
haud raro obsoleto; foliolis foliis 4-plo minoribus; ramis ? seepe 
iteratim innovatis; bracteis integerrimis raro serrulatis ; perianthii 
cornibus perbrevibus quidem paulo distinctioribus quam in typo.
