Fleischmannia profusa is named as new from El Salvador based on material with deltoid leaf blades, numerous axillary fascicles of leaves on the vegetative stems and c. 60 sharply obviously acuminate involucral bracts in 4-5 strongly gradate series.

ARDIYANI, M., ARDI, W. H., HUTABARAT, P. K. & POULSEN, A. D. 2021. Etlingera comosa, a new species (Zingiberaceae: Alpinioidea) from Central Sulawesi. Reinwardtia 20(2): 63−68. — comosa Ardiyani Ardi, and unusual Tentena, Sulawesi exhibiting terrestrial as well epiphytic habit is described here. It compared to the morphologically closest sublimata A.D.Poulsen, but differs in having tufted s...

Two new species of Curcuma, C. sattayasaii A. Chaveerach & R. Sudmoon and C. zedoaroides A. Chaveerach & T. Tanee with rhizomes traditionally used for many decades as cobra-bite antidotes are described and illustrated. Curcuma sattayasaii is similar to C. longa L., but differs in rhizome horizontally branching on ground; coma bracts pinkish-white or pinkish-pale green; corolla pale yellow with ...

Cynara scolymus L. is a medicinal plant frequently used in traditional medicine for liver diseases. The aim of this study is to evaluate the antimicrobial activity of the different parts of Artichoke. Maximum antimicrobial activity was observed with methanolic extract of bound phenols for (bract and heart) against Gram negative bacteria. The MIC values for bound phenols from heart were (63μg/ml...

Since Lycopersicon was separated from the closely related Solanum, the species of tomatoes have been reduced by taxonomic revisions to six (MULLER 1940) or seven (LUCKWILL 1g43), all probably indigenous to the West coast of South America or the adjacent Galapagos Islands. These species are naturally divided into two sections or subgenera: I. EULYCOPERSICON, containing the two edible and widely ...

Trichogonia cinerea is endemic to Brazil and occurs in areas of cerrado and campo rupestre. In this study, we characterized the glandular and non-glandular trichomes on the aerial parts of this species, determined the principal events in the development of the former, and identified the main constituents of the volatile oil produced in its aerial organs. Fully expanded leaves, internodes, flore...

Upward physical restraint of the normally horizontal bracts of poinsettia (Euphorbia pulcherrima Willd.) resulted in increased ethylene production and epinastic curvature of the petioles after 5 days. Downward restraint caused little change in ethylene production or epinasty, indicating that the enhanced ethylene production observed in petioles bent upwards is not due to the bending stress alon...

Guzmania panamensis (Bromeliaceae), a new species so far endemic to Veraguas province, Western Panama, is described and illustrated. The new species is recognized due to its peduncle much longer than the leaves and its red floral bracts, shorter than the yellow flowers. The new species is compared to morphologically similar species, namely Guzmania monostachia, Guzmania berteroniana, Guzmania e...

A new species, Alysicarpus poklianus Gholami & Pandey from Sinhgarh, Maharashtra, India is described. It is morphologically most similar to Alysicarpus hamosus but differs in having ovate leaves, rounded-ovate bracts, larger size of calyx, pods comprising 5-7 longer than broad joints with easily separable septa. In this study, a comprehensive description, and identification key of Alysicarpus p...

Protein extracted from boll weevil larvae causes abscission of cotton flower buds and debladed petioles. Abscission of buds is preceded by a rapid and persistent flaring of bracts; cell proliferation is induced in the abscission zone of debladed petioles. A possible mode of transmission of the agent from larva to bud tissue is discussed.
