72 NOTES ON THE ACANTHACEAE OF JAVA
Rostdlularia magnifolia Brem. n. spec.;typus: BÜNNEMEYER 12587 L;
maxime ut R. bonthainensis Brem., sed spicis angustis laxioribus, -foliis
majoribus, bracteis bracteolisque minoribus ab ea faciliter distinguenda.
Herba ramosa robustior. Rami internodiis primum bisulcatis 4-12 cm
longis et 1-2.5 mm diam., primum densius hirsuti, deinde plus minusve
glabrescentes. Folia petiolo hirsuto 2-9 mm longo instructa; lamina lanceolato-elliptiea,
2-11 cm longa et 0.9-3.7 cm Iata, utroque extremo
acuta, margine indistincte crenata, herbacea, supra hirsuta, subtus pilis
brevioribus praesertim costa nervisque pubescens, cystolithis subtus inconspieuis,
supra irregulariter sparsis, siec. nigrescentibus, nervis utroque
latere costae 3-10, utraque facie prominuUs. Spicae pedunculo usque ad
5 cm longe instructae, rachide pubescente usque ad 8 cm longa, ex internodiis
3-7 mm longis composita; spica 7 mm diam. Bracteae calyci plerumque
subaequilongae, infimae interdum breviores, omnes ovato-lanceolatae,
4-5 mm longae et 1.2-1.7 mm latae, acutae, apieem versus contractae
et conduplicatae, margine et costa carinata pilis tenuioribus densius
ciliatae, late hyalino-marginatae. Bracteolae lanceolatae, 3-4 mm longae
et 0.8--0.9 mm latae, ceterum ut bracteae. Calyx 4-partitus; lobi in tubum
0.4 mm altum connati, aequilongi, 3.7--4.0 mm longi et 0.8-1.0 mm lati,
ceterum ut bracteae bracteolaeque. Corolla 8.5 mm longa, extus glabra,
labio inferiore tamen ad apicem hirtello, tubo faucibus 0.6 mm longis
comprehensis 3.3 mm longo, labio superiore apice latius truncato, vix emarginato,
lobis labii inferioris 0.5 mm longis, rotundatis. Stamina filamentis
3.4 longis; thecae inaequilongae, superior 0.6 mm, inferior 0.7mm longa,
inferior calcare vix 0.2 -mm longe instructa; connectivum 0.3 mm latum.
Granula pollinis 27 ft longa, 17 ft Iata, 13 ft crassa. Ovarium glabrum,
1.2 mm altum. Stylus basi hirtellus 6 mm longus. CapsuIa glabra vel apiee
pilis perpaucis instructa, 6 mm longa et 1.7 mm Iata, parte solida 2 mm
longa. Semina carunculata.
Habitat terrae Celebieae partem austro-ocddentalem.
S.W. Celebes. Ravolo, alt. 900 m, BÜNNEMEYER 12587L, typus, H. VI.
This species is easily recognizable by the comparatively large size of
the leaves and the great length of the internodes and by the long and
narrow, rather lax spikes. The shortness of the spur at the base of the
lower theca and the glabrous ovary are also noteworthy features.
64. Rungia Nees.
The taxonomie 'P0sition of the -genus Rungia Nees was discussed by me
at some length at an earlier occasion (in Boissiera VII, p. 200, 1943), and
as since then no new facts bearing on this question have come to light, I
will not revert to it. Notwithstanding the similarity in the structure of the
fruit, the genus proved to be but distantly related to Dicliptera Juss.,
whereas it shows an unmistakable affinity to Rostellularia Reiehenb.
