ATTACHED LEAVES,INFLORESCENCES, AND FRUITS OF FAGOPSIS,AN EXTINCT GENUS OF FAGACEOUS AFFINITY FROM THE OLIGOCENE FLORISSANT FLORA OF COLORADO,U.S.A.

Specimens showing staminate and pistillate inflorescences attached to branches bearing Fagopsis longifolia (Lesq.) Hollick foliage, from the Oligocene Florissant flora of Colorado, permit a relatively complete characterization of the extinct Fagopsis plant. The alternately arranged simple leaves have pinnate craspedodromous venation and prominent simple teeth. Staminate inflorescences are globose on a stout peduncle and contain anthers with tricolporate pollen. Pistillate inflorescences are ovoid heads with compact, helically arranged three-flower units and are interpreted to have three styles per flower. The infructescence consists of small wedge-shaped cupules, each containing three tiny fruits, and subtended by a persistent bract. The cupules unravel from the swollen peduncle at maturity and are often dispersed as strings of adhering fruit-wedges which frequently take on a regular, more or less circular appearance. Fagopsis is unlike any living genus but has characters which support a relationship to the Fagaceae. Unlike extant members of the family, which typically have fruits adapted for animal dispersal, Fagopsis is less obviously specialized and perhaps adapted for wind dispersal. The striking differences in fruiting structures between Fagopsis and extant Fagaceae parallel the differences between the extant genera Platycarya and Juglans in the Juglandaceae, and Alnus and Corylus in the Betulaceae.     

STEROLS OF CHLORELLA. I. THE NATURALLY OCCURRING STEROLS OF CHLORELLA VULGARIS, C. ELLIPSOIDEA, AND C. SACCHAROPHILA

The characteristics of the sterols naturally occurring in threespecies of Chlorella were examined. The algae were grown heterotrophicallyon glucose. Sterols were extracted and isolated from the lipidfraction and were characterized by means of chemical and physicaltests. Chlorella vulgaris contained three sterols. Only the principalone, chondrillasterol, was identified. Chondrillasterol hasbeen isolated previously from the genus Scenedesmus. Chlorella ellipsoidea and Chlorella saccharophila were foundto contain sterols with ß-oriented alkyl groups atC-24 in contrast to the -oriented groups commonly found in higherplants. Poriferasterol was identified as the principal sterolof both algae. Clionasterol and 22-dihydrobrassicasterol wereidentified as the two secondary sterols present. None of thesesterols have previously been reported to occur in plants. Theisolation of 22-dihydrobrassicasterol has not been previouslyreported from any natural source. ¹Scientific Article A1153, Contribution No. 3623 of the Universityof Maryland Agricultural Experiment Station. ²This work has been supported in part by a grant from the NationalAeronautics and Space Administration.     

FRESHWATER DINOFLAGELLATES OF BELIZE,C.A.

Freshwater dinoflagellates have not previously been reported from Belize, although there has been extensive work with marine dinoflagellates and some work with other freshwater groups. Freshwater dinoflagellates are more frequently observed in standing water and none have been observed in the several streams and rivers sampled since 1990. The goal in 1998 was to examine water samples from small ponds within hours of collection to improve the chance of observing swimming dinoflagellates. A plankton net was used and whole water samples also were collected. A small brown water pond on a peninsula and 30m from the Caribbean yielded a bloom of Thompsodinium intermedium. Dinoflagellates, including Peridinium centenniale, Katodinium sp., and Peridinium sp. in the Umbonatum Group, were observed within “Crocodile pond” and “Lily pond” on the mainland.
