question: Which has more species Lamium or Colletia?
answer: Lamium
context: Title: Lamium maculatum
  Passage: Lamium maculatum (also known as spotted dead-nettle, spotted henbit and purple dragon) is a species of flowering plant in the family Lamiaceae, native throughout Europe and temperate Asia (Lebanon, Syria, Turkey, western China).
  Title: Plectranthus scutellarioides
  Passage: Plectranthus scutellarioides, commonly known as coleus, is a species of flowering plant in the family Lamiaceae (the mint or deadnettle family), native to southeast Asia through to Australia.  Typically growing to 60 - tall and wide, it is a bushy, woody-based evergreen perennial, widely grown for the highly decorative variegated leaves found in cultivated varieties.  Another common name is painted nettle, reflecting its relationship to deadnettles ("Lamium" species), which are in the same family.  (True nettles and their close kin are in the family Urticaceae.)  The synonyms Coleus blumei and Solenostemon scutellarioides are also widely used names for this species.
  Title: Lamium
  Passage: Lamium (dead-nettles) is a genus of about 40–50 species of flowering plants in the family Lamiaceae, of which it is the type genus.  They are all herbaceous plants native to Europe, Asia, and northern Africa, but several have become very successful weeds of crop fields and are now widely naturalised across much of the temperate world.
  Title: Laguna de los Padres
  Passage: Laguna de los Padres is a small lake located about 12 miles west of Mar del Plata, Argentina and roughly one mile east of Sierra de los Padres' hills.  The name of the lake as well as of the hills nearby has its origins in the Jesuit Fathers ("Padres") attempting to evangelize the region in the 17th century.  The lake has a length of 2,065 mt (6,884 feet) and a width of 1,701 mt (5,670 feet).  Its water is shallow and the aquatic flora, like algae, rushes and another species like the myriophyllum aquaticum, also kown in Argentina as "gambarussa," overpopulates the muddy bottom.  Woods of eucalyptus and pines surround the adjacent area, as well as some aboriginal shrub, like the colletia paradoxa, locally known as "curro".  The area also hosts the southernmost population of tala and some specimenes of sambucus.  The place had been open to the public since 1946.  Sport fishing is the main recreational activity, and there is a wharf for row boats in a small island linked to land by a causeway.  Watercraft with internal combustion power are not permitted on the lake.  Laguna de los Padres also hosted rowing events during the 1995 Pan American Games and 2006 South American Games.
  Title: Lamium orvala
  Passage: Lamium orvala, known as balm-leaved archangel, is a species of flowering plant in the family Lamiaceae, native to central eastern Europe (Austria, Italy, Hungary, Former Yugoslavia, Ukraine, Moldova).
  Title: Tritomegas bicolor
  Passage: Tritomegas bicolor, the pied shield bug, is a species of shield bug found in Europe.  The adult is black and white and 5.5 - long.  It is found across North Africa, Europe and Central Asia, although in the British Isles, it becomes rarer towards the north, and is absent from Scotland and Ireland.  "T. bicolor" lives mainly on the ground, but is also visible on its host plants — chiefly "Lamium" (dead nettles) and "Ballota nigra" (black horehound).
  Title: Colletia
  Passage: Colletia is a genus of flowering plants in the family Rhamnaceae, with 15 to 17 species of spiny shrubs. All species of this genus are native to southern South America.  They are non-legume nitrogen fixers.
  Title: Lamium amplexicaule
  Passage: Lamium amplexicaule, commonly known as henbit dead-nettle, common henbit, or greater henbit, is a species of "Lamium" native to Europe, Asia and northern Africa.
  Title: Brillantaisia
  Passage: Brillantaisia is a genus of plant in family Acanthaceae.  They are native to the African tropics and subtropics, including Madagascar.  They may grow from 20 cm to 2 m in height.  Their hirsute stems are square in cross-section and their heart-shaped leaves have an opposite arrangement.  Their purple or white pea-like flowers produce long, cigar-shaped seed pods.  They reproduce easily from seeds or vegetatively.  One species, "B. lamium", is invasive in Queensland.
