with clustered branches and dense foliage, which give it a singular 

 appearance. A good photo of its habit was taken by Dr. E. 

 Mjöberg and published by E. Gheel (K. Svenska Vet. Akad. 

 Handl., Bd. 52, No. 10, 1916, pi. I, fig. 2). 



It was common in the savannah forest at Derby and often 

 infested by the climber Tinospora smilacina. The somewhat curved 

 and flat brownish pods contain 2 — 7 seeds. The seeds are flat, 

 oblique-ovate, dull chestnut-brown, 13 — 16 mm long and 10 — 12 

 mm broad.

The well-known "Bird-flower" of the inhabitants (from the 

 likeness of the flower to a bird) was found in full flower and, on 

 the same individuals, with ripe fruits at Port Hedland(No. 1147, 

 3. Nov. 1914). It is a shrub or undershrub of medium size.

 herb or undershrub. 



I agree with Bentham (1. c.) in keeping C. trijoliastrum Willd. 

 apart from C. medicaginea Lam., with which F. v. Müller (1. c.) 

 has united it. My specimens are much like Indian C. trijoliastrum 

 and very different from Indian C. medicaginea, which is a de- 

 cumbent (prostrate) herb with smaller flowers, etc.

Broome (No. 1162, 5. Nov. 1914), in flower and with fruit; 

 an erect shrub or undershrub. 



F. v. Müller (1. c.) described this very characteristic species 

 from a single specimen without ripe fruits. As I have had good 

 material at hand and have grown the species in the Botanical 

 Garden of Copenhagen from seeds taken at Broome, I am able 

 to give an additional description of the flowers and fruits: 



Planta sufTruticosa, undique albo-tomentosa, præsertim in p<>- 

 dicellis et calycibus; floribus 3 — 6, umbellatis. Calycis lacinii in- 

 æquales, inflmo distincte longiore; corolla parva lilacina, glabra; 

 petalum supremum ovato-rotundatum, emarginatum, breviter un- 

 guiculatum, parte centrali lilacina (CC. 1 511 — 506), partibus peri- 

 phericis atque superficie tota externa pallide lilacinis (GG. 0496);
