A very elegant species, belonging to the section Eupanicum 
and placed by me in the group ,Parvifolia". The species of this 
group are perennial with more or less decumbent culms, diffuse 
panicles and small glabrous spikelets, the first glume more than 
half the length of the spikelet. Wellknown species of this group 
are Panicum cyanescens, Nees and Panicum parvi- 
folium, Lam.. Our plant has a very striking character, the 
lemma being papillose hairy, under a strong lense sparely obtected 
with very short blunt hyaline hairs. This character is present in 
Panicum helobium, Mez (ap Henr. in Meded. Rijks Herbarium 
no. 40 (1921) p. 52), Panicum cyanescens, Nees and Pani- 
cum parvifolium, Lam., but also in a recently described species: 
Panicum errabundum, Hirono.. 
Panicum species with hairy lemmas occur in other groups, 
such as „Urvilleana” and „Parviglumia” but the hairs are 
Scattered, appressed and silky. They differ totally from the curious 
very short hyaline ones mentioned above. 
Panicum polycladum, Erm. supposed by Exman to belong 
to our group, is a plant not growing in swamps, with pubescent or 
| hirtellous axis and branchlets of the panicle and small spikelets, 
15 mm long. This species belongs to the group „Cordo nt 
Panicum Niederleinii, Mez given as a nomen nudum by 
Erman is probably described by Mez under another name. 
Panicum Warmingii, Mez is not a valid species but ob 
the cleistogamous form of Panicum cordovense, Fourn.. ihe
