280 Mr. J. Miers on the Calyceracese/ 



manner a number of hollow tubular spaces, in three or four 

 irregularly concentric series, spread over the surface of the re- 

 ceptacle : each of the spaces thus constituted contains three or 

 four florets ; but the spaces here formed are wrongly designated 

 alveolae of the receptacle as this term is generally used by bota- 

 nists ; hence the term employed by Lessing was evidently mis- 

 understood by DeCandolle. I have drawn up the following as 

 a more correct expression of its generic features : — 



Gamocarpha, Dec. — Involucrum 5-6-phyllum ; foliola ovata, 

 crasso-carnosa, integra, margine subcartilaginea, subacuta, 

 imo in tubum brevissimum margini receptaculi coalitum 

 accreta. Receptaculum convexiusculum, carnosuni; palecs 

 magnse, foliacese, inter flores onustse, nonnullse liberse, spathu- 

 latse, plerseque ovatse, carnosulse, involucro sequilonga?, imo 

 latse, marginibus usque ad medium mutuo concretis in verti- 

 cilla 3-4 subconcentrica coalitae, istis e septis plurimis inter- 

 jectis in nidulos multos tubseformes 3-4-seriales constitutis : 

 hoc modo transmutatse, per totum receptaculum sparsse, et 

 imo eo arete accretse ; flores in singulo nidulo 3-4 imo insiti, 

 plerique fertiles, 5-meri, rarius abortu 4-meri. Calycis tubus, 

 ovario adnatus, margine discreto 5-dentato, dentibus sequali- 

 bus, ellipticis, acutis, erectis, carnosulis. Corolla regularis, 

 infundibuliformis, tubo gracili longo, limbo 5-lobo; lobis 

 oblongis, obtusiusculis, apice crassioribus et macula fusca 

 notatis, 3-nerviis. Stamina 5, inclusa; filamenta brevissima, 

 imo in annulum monadelphum constrictioni tubi insertum coa- 

 lita, superne libera, et introrsum arcuata : antherce inferne syn- 

 genesise, et breviter sagittata3, apice libera?, connectivo crasso 

 dorsali filamento continuo affixse. Ovarium obovatum, ultra 

 medium ad calycem accretum, apice liberum, conicum, 1-locu- 

 lare, 1-ovulatum. Stylus filiformis, longe exsertus, apice 

 incrassato-cylindraceus. Stiff ma minimum, globosum, papil- 

 loso-rugosum. Achsenium ignotum. 



Herba3 Chilenses, Andicolce, ccespitosce, acaules, rhizomate elon- 

 gatOy repente stolonifero, colles plurimos inter sistentes folii- 

 feros emittente ; folia subradicalia, congesta, lineari-spathulata, 

 intefferrima, carnosa ; scapi pauci, monocephali, folio longiores, 

 sapius nudi, rarius foliis L-2 supra medium donati, teretes, 

 carnosi; capitulum hemisphcericum, carnosum.
