    Hello Siggisan, I cannot guess so far which plant you are talking about. Could you provide pictures of the plant ? If so, we could follow the issue through this forum : http://www.guianasnatureforum.org/index.php?board=9.0

    Hello Friends... i'm looking for the name ,and evt.the family,of a woody bush[Arbustes],up to 2m.high,it grows in the savanne,useualy at open"spots.Of which the woody stems are very hard and twisted,the leaves also hard,the twigs are extended with leafless,twisted,long tops,with brown hair,that scratches and burn on the skin of the person that comes into contact with these hairy/brown twigtops..I have the same experience too.I guess that if this bush grows in the savahna's in Surinam,it should also occur in French Guyana;I hope you know something... Happy New Year ..... Siggisan

    Sure, what a beauty. Picture was taken on 9th September 2012, dry season in French Guiana. I have been told blooming did not occur every year, although all specimens of the species bloom together the same year.

    The most beautiful tree I ever saw,blooms before the leaves appear,after the dry season,i believe,because I see no leaves ....

    Aucune idée si cette plante est comestible ! Par contre, à ma connaissance, ce n'est pas elle qu'on appelle épinard pays...

    sugiero que se escriba sobre su habitat y lugares donde se ha informado de su existencia

    Sabicea aspera est maintenant présente sur le site. En tous cas la plante que je nomme comme ça, avec beaucoup d'incertitude. Sur le terrain, je distingue les deux espèces sur deux critères : inflorescences franchement sessiles --> S. aspera, inflorescences ramifiées, même brièvement --> S. panamensis, lobes de la corolle glabres --> S. aspera, lobes de la corolle ciliés --> S. panamensis. Je ne sais pas si ce dernier critère est pertinent d'ailleurs, en conclusion j'ai beaucoup de mal à distinguer les deux espèces...
    Je publie le message que Charlotte Taylor m'a envoyé il y a 5 ans, là aussi on lit l'incertitude:
    "Thank you very much for sending me the link to the nice photos. -- What this species is, is a good question in my opinion....

    First, I have never completely understood the separation of Sabicea aspera and Sabicea glabrescens. These have been separated by Steyermark and others by the size and shape of the stipules and the amount of pubescence. Steyermark separated Sabicea aspera by its broader stipules and denser pubescence; however plants with sparse pubescence that he identified as Sabicea glabrescens have stipules that are similar to those of Sabicea aspera. Both of these are relatively short broad stipules that are dark brown adaxially in dried specimens. There was a person who studied Sabicea several years ago, and concluded that these are varieties of the same species; however that work was never published.

    The plants you photographed have been included in Sabicea aspera in the herbarium identifications of some people -- however I think they are different. Sabicea aspera has sessile capitate inflorescences, that is, with the flowers and fruits sessile or subsessile. These plants have branched inflorescences with pedicellate flowers. For me, these either belong to or are more closely related to Sabicea panamensis (other names that have been used include Sabicea colombiana and Sabicea paraensis). This species does not get into Venezuela or Guyana, but it is found in the Amazon basin and ranges into French Guiana, where you are. We have more specimens here of your plant.

    The person who studied Sabicea included these plants with pedicellate flowers also in Sabicea aspera/glabrescens, and he may be correct but I am not convinced. Maybe you can go look at these in the field and see if you can find and separate Sabicea aspera/glabrescens with sessile glomerate inflorescences and the species in your photos; or maybe you can find variation that indicates that the person who studied Sabicea is correct and my idea is wrong. In either case, your field observations would be helpful.

    best, Charlotte"

    Finalement, maintenant que l'ai croisé, je vois mieux ce qu'est Casearia rusbyana, les feuilles sont bien plus grandes que celles de C. grandiflora.

    Begonia hirsuta Aubl. 1775!
