A large number of specimens used as original material for the description of new species were destroyed in the bombing of the Berlin-Dahlem herbarium, B, in 1943. Six lectotypes are designated here for Cordia discolor Cham., Cordia multispicata Cham., Cordia tobagensis Urb. and its variety broadwayi Urb. in the Cordiaceae and for Tournefortia paniculata Cham. and Tournefortia ulei Vaupel in the...

1. Immature, male Wistar rats were allocated to one of six groups and caged individually. The first group was given a semi-synthetic diet containing 38 mg iron and 55 mg zinc/kg (basal group). The second and third groups were given a diet containing 10 mg Zn and 12 mg Fe/kg respectively (low-Zn and low-Fe groups). Groups four, five and six were given similar diets containing 20 g Gypsophila sap...

The article describes a new hybrid namely Gypsophila × moldavica Pînzaru (G. glomerata G. collina), formed under ex situ conditions, in the author's private garden. Arguments have been brought to support claim of recognizing species Adams and it is considered appropriate synonymize pallasii Ikonn.

Introduction. The root-lesion nematodes, Pratylenchus spp., have a wide host range and reduce the yield of different crops. Information on diversity species is scarce in Costa Rica. Objective. To identify associated with 12 crops based D3 region 28S rDNA gene. Materials methods. During 2013 to 2015, root samples were collected Alajuela, Cartago, Guanacaste, Heredia, San José rice (Oryza sativa)...

A novel C-28 tetraglycoside of quillaic acid (1) has been isolated from G ypsophila capil­ laris. The structure was elucidated by 1 D NM R (N O E difference, DEPT, selective 13C{1H} INEPT), 2D NMR ^ H /H and !H ,13C COSY, ‘H /H /H RELAY, ROESY and TOCSY) and other spectroscopic and chromatographic evidences. Conformational dynamics within the tetrasaccharide part were estimated from NOE respons...

Two new triterpenoid saponins (1, 2) were isolated from the roots of Gypsophila altissima L. (Caryophyllaceae), together with a known compound (3). The structures of new saponins were established as quillaic acid 3-O-beta-D-xylopyranosyl-(1-->3)-beta-D-glucuronopyranoside (1), and 3-O-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-beta-D-glucuronopyranosyl quillaic acid 28-O-(6-...
