Protologue - Latin original
Foliis ellipticis integerrimis vel apice parce subdentatis, margine revoluto, utrinque glaberrimis, basi attenuata;
Ramuli cylindracei, subcurvati, internodiis unciam dimidiam et paullo longioribus, cortice laeviusculo, griseo-fuscescente; parte superiore foliis circiter 8 obsita, inferiore nuda vel inflorescentiae glomerulis obsita; Gemmula terminalis lateralis, subulata, stipulacea; Folia disticha, patula, ochrea brevissimia cauli adnata, cicatrice adsecendente, petiolus breviusculus (3"' longus", lamina elliptica (poll. 4 longa 1 1/2 lata), apice paullo acuminata, integerrima v. paucidentata; costatio debilis excurrens, costae laterales 6 filiformes, secundariae tenerrimae, diffusae et subhorizontaliter simpliciter et parce furcatim anastomosantes; pagina superior et inferior glaberrima, prior lucida posterior prima tantum juventute pilis maxime tenerrimis, adpressis obsita; Inflorescentiae ex ramuli parte anni praecedentis erumpentes, numerosae, glomeratae, singulae ex octo circiter spiculis compositae; Spiculae tenerae, breviusculae, vix pollicem 1/2 longae, rhachi abscondita, vix pilosa; Flosculi 15-18, bracteis acutis, mucronatis, squamiformibus fulti; bracteolae filiformes; Sepala subulato-lanceolata flexuosa 5 - 6; Stamen lineare, cruribus distantibus; Pistillum turbinatum, stylo conspicuo, stigmatibus obtusis, conniventibus; Fructus capsularis, subgloboso-trigonus, brevissime mucronatus, glaber, sessilis; Placentatio et semen uti in reliquis generis speciebus;
Adnotatio vix a L. myricoide acute distingui potest; sepala angustiora plerumque 6, capsula globosa, sessilis, breviter mucronata, foliorum aspectus et consistentia a prior distingunt.
Leaf elliptical entire or apex moderately subdentate, margin revolute, both sides hairless, base attenuate;
Twig cylindrical, somewhat curved, internode approximately 1.5 inches and a little longer, bark moderately smooth, grey-brown; leaf veins partly superior circa 8, leaf below naked or covered over with densely clustered inflorescence; bud terminal lateral, subulate, stipulate; Leaf distichous, outspread, sheathed by stipules extremely short stem adnate, scars ascending, petiole short (1/3 inch long), lamina elliptical (4 inches long 1.5 inches wide), apex a little acuminate, entire to few toothed; midrib extending a little beyond the apex, vein laterals 6 thread like, secondary veins very thin diffuse and subhorizontal only and moderately forked anastomosing; surface above and below hairless, young leaves covered with very thin adpressed hairs,
later shiny; Inflorescence breaking partly out of the twig the preceding year, numerous, densely clustered, composed of circa 1 to 8 spikes; Spike very thin, short, barely 0.5 inch long, rhachis hidden, barely pilose; Flower 15-18, bract acute, supported by scale mucronate shaped; bracteolate very thin; Sepal subulate-lanceolate zigzagged 5-6; Stamen linear, far removed from cross shape; Pistil turbinate, style conspicuous, covered over with converging stigma; Fruit capsule, subglobose-trigonal, short mucronate, hairless, sessile; Placentation and seed as other genus species;
Annotation: barely different from L. myricoide with keen eyesight it is possible to distinguish apart; sepal narrow very frequently 6, capsule globose, sessile, short mucronate, leaf appearance and texture from the first discernible.
