167 



(5 ad 16 mm), bracteis spicularum densis plus minus occulta. 

 Bracteae primariae 45 ad 25 mm longae, oblongae mucronatae 

 superiores minores acutae ad 20 mm longae apice et basi minute 

 puberulae, erectae. Florum paria 2 vel 3 bracteolis teneris 

 paucis. Fl. brevipedicellati ad 25 mm longi. Ovarium teres 

 (3 mm) appresse villosum, triloculare, triovulatum. Sepala 

 anguste lanceolata apice acuta incurva 7 mm longa. Floris 

 tubus gracilis elongatus (16 mm longus), petala lineari-oblonga 

 genitalia superantia circ. medio tubo inserta ±10 ad 12 mm 

 longa. Staminodium exterius singulum valde elongatum lineare 

 7 mm longum, 1.5 mm latum, labellum (std. callosum) elongatum 

 ellipticum apice dilatatum emarginatum valde concavum, callo 

 superne tenui glabro, lobulo basali velutino (±6 mm longum). 

 Cucullum multo brevius, appendicula haud magna, basi auri- 

 culata munitum, stamen fertile subfiliforme, loculo petaloideo 

 angusto inconspicuo 4 mm longum. Caryopsis parva (10 mm 

 longa, 5 mm lata) teres oblonga apice rotundata et calyce 

 coronata, uni latere concava, pericarpio tenui stramineo appresse 

 hirsuto, abortu nunc unilocularis indehiscens, monospermus 

 (teste Rumphius dispermus). Semen teres apice acutum, basi 

 arillo magno nigro bipartito lobis magnis attenuatis instructum. 

 Embryo leviter curvatum. 



Doctor Robinson's hypothesis that the specimen of his collec- 

 tion, cited above, represented Folium buccinatum album Rumph. 

 was a very ingenious one. Rumphius's description tallies so 

 exactly with the specimens that it would be impossible to find 

 another species that better agrees with it. It is a very fine new 

 species of Phacelophrynium, differing from the generic diagnosis 

 in its 1- or 2-celled nuts (instead of 3-celled 3-valved capsules) 

 and its long corolla-tube. There is, however, only one exterior 

 staminode, and this character together with the whole habit 

 of the species, which closely resembles Phacelophrynium inter- 

 ruptum K. Schum., induces me to place it in Phacelophrynium 

 rather than to propose for it a new generic name. The fruit 

 is rather remarkable and is to be compared only with that of 

 Halopegia K. Schumann.
