Stellaria mannii Hook. View in CoL f.

( Figs 4 View FIG ; 5C View FIG ; 6 View FIG I-L)

Journal of the Linnean Society VII: 183 (1864). — Type: Cammeroon mountains, 2100 m, XII.1862, G. Mann 1940 (holo-, K not seen, photo at LP!).

Remarks

Stellaria is a cosmopolitan genus widespread in moderate climates and at low and high altitudes. Stellaria mannii grows near streams, in wet forest understory, in tropical and subtropical Africa, Madagascar, Sao Tomé, Bioko, Comores and Mascarene Islands (Fig. 1, oblique lines).

In a loan from P to LP of S. mannii , there was one specimen of this species collected by Commerson, with handwriting on the label probably also by Commerson ( Monnier et al. 1993: 16): France, Commerson P 215108, “Isle de Bourbon, Des Hauts de Bourbon, Dans les Bois, Aoust-1771”.

The date of collection of this specimen, August 1771, indicates that the expedition was at that time in “Isle de Bourbon”. Monnier et al. (1993) said that they returned to “ Isle de France ” on February 1771. There is a difference of seven months between these dates.

OBSERVATIONS

ABOUT THE LABELS AND HANDWRITING

The handwriting of “de magellan, Comon, les 2 plantes” in specimen A and “de magellan” in specimen B ( Figs 2 View FIG ; 3 View FIG ; 5A, B View FIG ) is similar to that of “Isle de Bourbon Con ” and “de magellan Comon ” in specimen C ( Figs 4 View FIG ; 5C View FIG ). This handwriting probably belongs to Lamarck (cf. Burdet 1976: 151;

Monnier et al. 1993: 28) and was done after Commerson’s death.

The handwriting of “N. 101, Type. vidr. Stellaria rotundifolia ” in specimen A ( Figs 2 View FIG ; 5A View FIG ) is different from the above mentioned, but similar to the handwriting of: “Commerson cum No. 101” in specimen B ( Figs 3 View FIG ; 5B View FIG ). Besides, “les 2 plantes” mentioned in B are specimens A and B, having both the same number, 101; although in A it says “ vidr. Stellaria rotundifolia ”.

Conclusion

Probably specimen B ( Drymaria cordata ) was collected from Tahiti to Sumatra and Java Islands, in the middle part of Commerson’s travel, while specimens A ( Cerastium lanceolatum ) and C ( Stellaria mannii ) were collected during the last part of Commerson’s travel, instead of at “de magellan”, all of which is confirmed by the specimens determinavit.

ABOUT OTHER PLANT NAMED

STELLARIA ROTUNDIFOLIA

Hariot (1900) in his Liste des phanérogames listed four Caryophyllaceae collected by Willems et Rousson in “ Terre de Feu ”. Those species are: Colobanthus quitensis (Kunth) Bartl. (P), Cerastium arvense L. (P 00199398), C. arvense var. strictum Hook. f. (P 00199400) and Stellaria rotundifolia Poir. (P 00199401). This last specimen was labelled by David Moore with the name? Stellaria media (L.) Vill. in October 1974. However, this fourth specimen does not belong to Caryophyllaceae .

This last specimen (P 00199401) has four plants, with three verticillate leaves each, without roots and flowers.Leaves are more or less membranaceous, with reticulate venation; a small papery bract (cataphyll?) is near the base of shaft. One of those plants has a small bud. Comparing the plants with descriptions and drawings in Flora Patagónica ( Correa 1969: 190, fig. 168) it was possible to arrive to Codonorchis a monotypic genus of Orchidaceae ( C. lessonii (Brongn.) Lindl. ). Afterwards, the specimen was also compared with the type specimen of Epipactis lessoni, d’Urville 410, I. Soledad, type P 00328371 (P, not seen; LP!) and directly with herbarium specimens of that species at LP. Many specimens have their leaves very well preserved as the one collected by Willems et Rousson (e.g., Argentina M. Gentili s.n. (LP), Prov. Neuquén, Parque Nacional Lanín, Pucará, 12.XII.1970). The leaves well preserved in all these specimens are very similar.

Conclusion

This specimen does not belong to Caryophyllaceae . Probably it is an Orchidaceae , but it has no flowers.
